Briefly describe the maintenance method of laser scattering particle size distributor

The size of the particles is called the particle size or particle diameter, and the distribution of the content of the particle population at different particle sizes is called the particle size
.

The laser scattering particle size distributor adopts imported He-Ne laser light source, the laser power is more stable, and the warm-up time is further shortened
.

Combined with its modern intelligent measurement control analysis software and automatic injection measurement hardware system, the use experience has been improved, the particle size test process is more concise and efficient, the test results are more stable and reliable, and the interpretation and comparison of particle size test reports is more intuitive and simple
.

The particle size differential distribution curve can intuitively obtain the particle size information of the particle size concentration area and the discrete region, and it can be easily seen that the main particles of the current curve corresponding to the sample are concentrated in about 10um (intermediate particle size), a small amount of large particles is close to 100um, and the size of a small number of small particles is about 1um (boundary particle size).

Sometimes we also use differential curves to look at particle sizes
with high particle distribution abundance.

What Xiaobian wants to share with you today is the maintenance method of laser scattering particle size distributor: 1.
Clean maintenance
.

After each experiment, it must be cleaned in time to avoid contaminating the internal system of the experiment and affecting the test results
.

After a period of use, the sample window
should also be cleaned regularly.

2.
Whether the instrument hardware is normal, whether it can be connected to the computer normally, and whether it can make a benchmark as normal; Whether the ultrasonic stirring circulation system can work
properly.

The circulation is mainly driven by the water pump in the instrument, and it is normal
for water to flow out of the circular hole above the sample cell and no obvious bubbles.

3.
Whether the optical path is normal
.

First of all, the laser tube is not able to work normally and can produce light; Secondly, whether the optical path is polarized or not, it can be obscured in front of the sample window, and after the approximate circle is normal, the light can not come out from the green detector on the right hand side of the frontal instrument, and the light is almost circular as normal
.

4.
Judgment
of benchmarks.

Most of the problems of the instrument is not normal can be judged by the benchmark, and how to make the benchmark is particularly important
.

Add water to the sample cell (taking water as an example), drain button, there is water discharge closed, open the circulation button, the sample cell hole has water out of the subject as the standard
.

Then operate the software as a benchmark, and a series of small blue columns come out as a reference chart
.
