How to quickly complete the Karl Fischer moisture test when the ambient humidity exceeds 60%
Date: 2021-9-6

As the carrier gas, air plays a very important role in the traditional automatic Karl Fischer moisture analyzer. Generally, the air needs to be dried, but the degree of drying is restricted by the humidity of the air, that is, the greater the humidity of the air, the greater the water content after drying. Therefore, when using an automatic moisture analyzer tester, it is necessary to first detect the moisture content of the carrier gas after drying in order to deduct the influence of the moisture content of the carrier gas in subsequent measurement calculations. The humidity of the air changes all the time, but the moisture content of the carrier gas cannot be updated in real time during the test. Therefore, the moisture analyzer that uses air as the carrier gas faces challenges in terms of repeatability and re-producibility.

In terms of cost control, the use of air as a carrier gas will also bring a lot of cost consumption issues. Firstly, the expenditure for the air drying device and filtering device is also included. Secondly, usage of Karl Fischer reagent increases when caused by insufficient dry air entering the titration cell within the sample. Thirdly, the cost of labor and time increases when air is used as the carrier gas mode. The time it takes to detect the moisture content in the air and the sample will be greatly lengthened as the humidity increases.

How to eliminate or reduce the influence of moisture in the air? To tackle these challenges is to improve the process of the carrier gas entering Karl Fischer, which reduces the water content of the carrier gas or completely eliminate the influence of the external carrier gas. ECH, a company based in Germany, has developed a non-external carrier gas trace moisture tester to address these efficiency issues.

The biggest advantage of ECH automatic non-external carrier gas trace moisture tester is that no air carrier gas is needed, which eliminates the influence of air humidity. Thereby saving more cost and time.

ECH automatic non-external carrier gas trace moisture tester, equipped with a variety of specifications of the sample tray and adjustable-size heating furnace, can easily increase the detection volume by increasing the size of the sample tray when the detection volume increases.

Currently, the ECH automatic non-external carrier gas trace moisture tester has a very good reputation during customer trials as the customers very much recognize that the ECH automatic non-external carrier gas trace moisture tester is faster, better, and stronger in use.
