New Headspace Oven Automates Water Separation from Difficult Samples Prior to Titration
Mar 25 2021
Titration is one of the oldest methods for content determination in chemistry, commonly used to ascertain an unknown component within a solution. This is achieved by monitoring the final reaction of a quantified reagent that has been introduced to the sample, using an indicator such as colour or pH.
Traditionally, titration, or volumetry as it is also known, is performed quickly and economically using basic laboratory apparatus such as a beaker, stirrer, glass burette and maybe a simple pH meter.
The actual test itself is not time consuming but when you consider the importance of measurement uncertainty and traceability and compare it to the overall time of an automated experiment, the advantages of the latest technologies on offer become obvious. Instruments, such as Xylem's TitroLine® 7800 with IDS technology, not only take away the pain and potential errors caused by human interpretation of manual titration end points and subsequent empirical calculations but can also provide data security and auditability thanks to its innovative digital signal handling and sensor recognition. It is ideal for applications requiring compliance with FDA regulation 21 CR Part 11.
Importantly, Xylem's latest TitroLine® KF solution for semi or fully automated titration of water in liquids, solids and even pastes using the new TO 7280 headspace oven not only automates the measurement process but handles sample preparation too. This provides for a faster throughput of samples, more reliable results, reduced costs and offers the benefit of a safer experiment by removing the need to handle solvents, analytes and specialty gases.
Do you want to learn more about the theory of pH measurement, titration or conductivity? If you do, please contact Xylem and ask for one of their handbooks.
