Four points to note about multi-parameter water quality analyzers

Four points to note about multi-parameter water quality analyzers Moisture analyzers are widely used in industry, agriculture, scientific research institutions and other industries
.

It can carry out content test and data printing of free moisture contained in samples of tobacco, paper, food, tea, feed, grain, chemical raw materials, textile raw materials,
etc.

So, what should be paid attention to when using it? Let’s find out with me below
.

Note on the use of multi-parameter water quality analyzer: 1.
The system is completely closed
.

The connections of the Karl Fischer reagent liquid circuit should be fastened, from the reagent bottle to the metering pump to the reaction tank, otherwise the reagent leakage will directly affect the test result
.

Another problem with its non-airtightness is that the Karl Fischer reagent absorbs air moisture during the test, which will cause the titration end point to be delayed
.

2.
Accurate sampling of water quality analyzers
.

When calibrating Karl Fischer reagent, 10 mg of water should be used, and a 10ul sampler should be used as much as possible, which is not only accurate and fast, but also prevents water droplets from sticking
.

Similarly, there are similar problems when taking methanol reagent and ethyl ester.
After taking and placing, attention should be paid to shorten the opening time of the reaction tank as much as possible
.

 　　3.
Adjust the magnetic stirring speed of the water quality analyzer
.

In the reaction tank, since the titration reagent is added locally and not in the same place with the electrode, the stirring speed should be as fast as possible so as not to form turbulent flow, so that the end point can be reached
.

 　　4.
The titration speed setting of the water quality analyzer should be fast first and then slow
.

Titrate quickly at first to minimize test time, and be slow as you approach the end point, which improves dosing
.

 　　The above is the relevant introduction to the key points of the multi-parameter water quality analyzer.
I believe that everyone has a corresponding understanding of this after reading, and I hope it will be helpful to everyone
