Things to Know About Titrator Systems

Titration refers to quantitative chemical analysis to find the concentration of a specific analyte. It is widely used in the food industry as it allows the manufacturer to determine the reactant’s concentration in a given sample. 

A titrator is a useful device to discover the amount of salt or sugar in the product or concentration of Vitamin E or C, affecting product colour. Here we have discussed essential things you should know about titrator systems.

How Does It Work?

A titration system consists of an electric burette and a sensor attached to an amplifier. The titrator also comes with an in-built microcomputer. During titration, the system measures the signal coming from the sensor and uses it to control the titrant’s addition with an electric burette. When the procedure’s endpoint is reached, the system calculates the total amount of titrant added and converts it to value.

The market is full of a wide range of titrator systems, including standalone potentiometric titrator for general applications and advanced titrators for precise calculations.The titrator should be able to perform the following tasks effectively. 

  • Calculate endpoints accurately for different curves or shapes
  • Remove endpoints that are not needed in the final analysis

Here we have discussed important features and titrator components that you need to focus on while buying a titrator system.

Faster Processing 

The titrator system you buy should allow parallel analyses of samples that will reduce the testing time. The system should support automated sample processing reducing the probability of human interference and contamination of the samples. You need to look for patented technology that helps achieve non-contact handling of samples.

Compliance

The food processing industry is highly regulated, and compliance with the testing instruments is a crucial factor. The titrator you buy for your food processing business should be compliant with EudraLex Volume 4, Annex 11, and 21 CFR, Part 11. The compliance requirements change with applications. Hence, you need to ensure the device meets the right compliance requirements. 

Easy to Operate 

Large parts of the titration methods are generally automated. The system you purchase should be easy to use and integrate with your laboratory information management system to exchange and store data. Such features reduce the need for double data entries that increase the probability of wrong entries and affect the processes’ results.  

Types of Sensors

Sensors are essential components of the titration process. The right type of sensor for the system depends on the analysis that needs to be performed. Here we have listed the types of sensors for different applications. 

  • Ph electrode – if you are performing acid-base titrations, you need a sensor that can determine the juice’s acidity or solvent in question
  • Silver electrode – ideal for precipitation titration like determining table salt concentration in soy sauce 
  • Platinum electrode – ideal for redox titrations like determining the Vitamin C content in Orange juice
  • Ion-selective electrode – helps determine select ions like calcium in solution

Preamplifier

You need to ensure the preamplifier is compatible with the sensor. If the sensor is not fully compatible, it will lead to inaccurate readings. 

To sum up, these are some of the things you should know about the titrator. It will help you select the right system for your food business.
