How to weigh the advantage of features

It is quite a complicated task to arrive at conclusion when you come across different models with several features and specifications, each company stirring at their own U.S.P. sometimes they are totally irrelevant & at times they are not truly significant to your work – even if taking futuristic requirements in mind.  If they are given to you without any extra cost it is not a problem but if some cost is attached to it, then definitely a due though required.

Actually, there is a very simple technique which can be used effectively.  Any feature for that matter, just ask one question to yourself “So What? What is in it of me”? If the feature is having certain advantage look for the real benefit you are getting out of it.

When a designer develops a certain product he goes by various ways.  Although human brains work differently, the basic requirements are same – they have to be there.  But the intention of these entirely depend upon the imagination and understanding of the users requirement in depth.  And then come the sales gimmicks!

Further it also depends upon what technology he is using.  And that’s why & where users get confused.  Users many times are unable to identify the inside story. They may get carried away by many unwanted specifications.  With PC or microcontroller it is easy to give wide range of measurement irrespective of basic limitations.  For example pH range will be shown as 0-20 pH or temperature will be shown as ambient to 999°C. Such specifications are generally kept to eliminate certain unfortunate manufactures.  Now let us see some of the features and also see their advantages and benefits.

On Line Curve : By this feature the operator is able to see how the titration is progressing.  This will also give derivate curve simultaneously, indicates where are the significant peaks.

Just ask yourself what benefit you are getting out of this feature. Well, YES it is very useful to have advance intimation before you actually get the result.  If this benefit appeals to you, you can certainly increase your budget.

Automatic Burette Recognition :

By this feature you can ensure which titrant you are using.  This has a definite advantage as you can know the contents like name & normality of the titrant well before you start the titration.  The benefit you get is avoiding wastage of time & chemicals.  But still you can ask yourself – does this feature is beneficial to you.  If yes surely you can go for the model which will   give this facility to you.

However, if you are having just one or two types of titrations, there is not much substance for this feature.  At the same time, where you are having wide range of titrants, it is of advantage to have more numbers of burette available with you to use the above feature effectively.  Sometimes people go for the model with such facility but they tend to be compromising on number of such extra interchangeable burette assemblies.  This is not a wise choice.  This way the very purpose of having automatic burette recognition facility is lost.

“Stand alone” model or “PC through operation”:

This is another feature where you stand at the dilemma.  Actually having a standalone model where data can be transferred to PC is also a good feature as you do not have to make provision in your budget for PC, added requirement of table space to keep PC.  However you have to ensure that it has a facility to print using the printer available in the market.  Also make sure that it has a facility to take the data on pen drive so that you can take to nearby PC where you can transfer the data.

You have advantage & limitations on both the types but you have to decide for your best   It is also advisable to check if the stand alone  model can be further upgraded in future for PC through operation.

Now a days some manufacturers give facility of “on line “support. This is very useful feature because you can get instant support.  The supplier’s service engineer cannot be present at each and every location.  You have to give some consideration to this reality.  Although there may not be a fault with the instrument, but there may be a problem with the operator.  He might change the job and someone else might have joined, he may not be trained or anything for that matter. The “On Line “support will considerably keep the down time under control unless of course there is some hardware / mechanical problem, but 90 % of the problems are associated with things which are “Outside” of the instrument. If your lab is in remote location, you have to give considerable weight age for such facility.

Moisture Estimation using Karl Fischer Titrator:

Quite often this facility is given as an option.  Whether to go for this add on or procure a separate titrator for moisture estimation is creating dilemma.  Simple thumb rule is to check the proportion of work and how frequently you are required to carry out it. And decide.  However if the titrator is already to be used for variety of titrants adding KF facility also makes the things bit complicated.  The titration using the Karl Fischer titrator is somewhat different than other potentiometric titrations, in the sense that it requires neutralization.  Hence every time you switch over, there is wastage of time & chemicals like Methanol & KF reagent.  Although initial cost of two separate Karl Fischer titrators may make you inclined towards less costly option it will have above draw backs.  In all practical purpose two separate instruments is a better choice.

pH stat titrations :

Unless otherwise specifically do not go for this as an attachment.  Keeping the titrator decided to this work is a better option. pH Stat requires long duration work and if the titrator is all the time engaged for pH Stat, other samples will wait.  Further pH Stat is temperature controlled titration.  Ensure that a heating / cooling system is available for maintaining desired temperature with accuracy.  It should be compact so that it will not look clumsy, at the same time achieving the desired temperature quickly enough.  Large size water baths will not work as they take long time.  A solid state cooling / heating bath will be quite useful as it occupies less bench space.

Method Development:

Method development is bit tedious and yet important aspects of titration.  It is dependent on various factors and the instrument adopted for the same should satisfy certain requirements such as dose steps, variable endpoint sensitivity, ml Vs mv report, variable endpoint criteria, dead stop criteria, start criteria for more than one step, Endpoint anticipation for unknown sample and last but not the least a user defined formula apart from the standard formulas.

The repost generated from the instrument also plays a vital role in method development and validation.  The report generated from the equipment should be such that even a lay man can understand the details and proceed accordingly.

Its Kjeldahl Protein Analyzer is a special instrument that can automatize the Kjeldahl method and make protein analysis easier and speedier.

This Kjeldahl Protein Analyzer uses an array of chemical processes to transform nitrogen contained in the sample into ammonium sulfate and then quantify it by the colorimetry or titration method.

The amount of nitrogen found in the sample is believed to be directly proportional to the protein content. Hence, it is possible to determine the amount of protein measured by multiplying the nitrogen content with an amount of conversion.

How Kjeldahl Protein Analyzer Works

Protein analysis is vital across various fields like agriculture, the food industry, and biochemistry. An accurate determination of the amount of protein is essential to guarantee the products’ quality and assess the nutritional value of food items.

One method used for protein analysis includes one called the Kjeldahl method. Let us examine how the Kjeldahl protein analyzer operates, the steps involved in the process of analysis as well as the importance of digestion.

Kjeldahl method

The Kjeldahl method is a popular method to determine the protein content of an item. Its name is derived from its creator, Johan Kjeldahl, a Danish chemical engineer who devised the technique in 1883.

The procedure involves three primary stages: digestion of samples distillation, titration Kjeldahl analysis of proteins automates these processes and gives precise and accurate results.

The process of digestion of samples is the initial stage of the Kjeldahl method. This process aims to disintegrate the protein within the sample and transform it into an easily assessed form.

The sample is weighed and placed in an acid-degradation flask with concentrated sulfuric acid and a catalyst (such as copper Sulphate). It is heated inside an aluminium until the sample has been completely digested. The digestion process takes place as it is hydrolyzed to its amino acid constituents, and nitrogen is converted to ammonium ions.

After digestion, the sample is distilled to separate ammonium ions and the remainder of the matrix. The distillation process includes adding sodium hydroxide into the flask for digestion to convert ammonium ions to gas. Ammonia gas is transferred to the receiving flask, where boric acid solutions absorb it. It is prepared for the next stage, which is titration.

Titration is the last process of the Kjeldahl method. The goal of this process is to measure the sample’s nitrogen content, which is a measurement of the protein amount. Boric acid solutions containing ammonia gas can be titrated using a standard acid solution, like hydrochloric acid.

The titration’s end point occurs when all the ammonia reacts with the acid and the solution is acidic. This amount used is used to determine the nitrogen content of the sample. The Kjeldahl protein analyzer automates each of the steps to produce exact and precise outcomes.

The sample is weighed before being transferred into the digestion flask promptly. The digestion block warms the sample up to a specified temperature for a fixed duration, ensuring that the sample is completely digested. The distillation process is automated, as is the distillate stored in a flask for receiving. The titration process is performed by a titration machine that guarantees accurate and exact results.

The digestion of samples is an essential process in the Kjeldahl method. It is necessary to ensure that the sample has been fully digested to get precise results. Incomplete digestion could result in an underestimation of the protein amount.

The factors that affect digestion include:

  • The quantity of sulfuric acid used.
  • The time and temperature.

It is vital to adjust these parameters for each sample to ensure complete digestion.

Sample Preparation for Kjeldahl Protein Analyzer

The Kjeldahl method is an extensively used method to determine the amount of protein present in the sample. The preparation of samples is an essential element of Kjeldahl’s analysis. The analysis’s precision and accuracy depend on the sample preparation caliber.

Selection of Samples

The sample selection to be used in the Kjeldahl analysis is vital. The samples must be representative of the sample that will be studied. The choice of samples must be according to their importance in the research questions or purpose of the study.

In the food industry, the samples are generally taken from batches of items. It is crucial to ensure you get samples taken randomly and represent the entire batch. For instance, if the batch comprises various types of beef, samples ought to take from varied areas of each kind of meat.

Preparation of Samples

The preparation of the samples is the next crucial stage in an analysis like the Kjeldahl analysis. Samples must be carefully prepared to ensure exact results. The preparation of samples requires many steps, including grinding, homogenization, as well as drying.

Grinding the sample should be crushed to the point of being a fine powder for complete digestion. The grinding process must be performed in a manner that does not cause contamination and also ensures that the sample is homogeneous. For instance, the samples are typically ground with the food processor for food processing.


The homogenization process of samples is an important stage in the preparation of samples. The sample should be homogenized to ensure it represents the whole sample. The homogenization process should be carried out in a manner that does not cause contamination and ensures an even distribution of the specimen. For instance, samples for food processing are typically homogenized with an abrasive or homogenizer.


The sample should be dried to an even weight to guarantee accurate results. Drying should be conducted in a way that doesn’t cause contamination and maintains that the sample is homogeneous. For instance, samples in agriculture are typically dried in an oven or freeze dryer.

Importance of Homogeneity of Samples

Homogeneity in samples is a crucial element that determines the precision and accuracy that is a part of Kjeldahl’s analysis. Homogeneity guarantees that the samples are representative of the total population. An incomplete homogenization could lead to significant mistakes in the analysis since certain parts of the sample might contain higher or lower protein content than others.

The homogeneity of the samples is crucial when studying heterogeneous samples like vegetables or meat. The samples have to be homogenized to ensure that every sampled part represents the whole sample. If the sample isn’t homogenized correctly, then the analysis outcomes might not be precise or accurate.
