FAQ

The working principle of flue gas analyzer, with the brand

The electrochemical principle is the instrument is used in electrochemical sensor, the sensor has some chemical substances, these substances and specific gases (such as chemical sensors on the CO met CO, a chemical reaction will occur, to determine the concentration of CO according to the size of the reaction) reaction. The sensor is characterized by fast response and short life (usually 2-4 years)

What does "ABC classification" mean for test equipment? Need to be specific

The instrument belongs to the equipment, and the equipment can be classified into class a key equipment, B class general equipment and C class equipment according to the importance, the advanced technology and the value

What are the specific methods of chemical instrument analysis?

A chemical analysis is a method of determining the composition and content of a substance to be measured by using a chemical reaction and its measurement relationship.

What is the basis for building an analytical instrument?

There are different effects in different parts, and then the signal conversion system, the atomic absorption of light, we detect the intensity of light is not absorbed, the detector for photomultiplier tube, through signal amplification, digital analog conversion to obtain the transmittance or absorbance, directly on the instrument display can be read. In fact, this part contains the amplified recording and readout device. Different instruments are similar. A well please correct me.

Main features of instrumental analysis

1. High sensitivity: most instrumental analysis is suitable for trace and trace analysis. For example, the absolute sensitivity of some elements to 10^-14g can be determined by atomic absorption spectrometry. The electronic spectra of even up to 10^-18g, the relative sensitivity of the?? - 1 - 1, ng and even smaller?.2, sampling amount is few: chemical analysis uses 10^-1 ~ 10^-4g; instrument analysis sample is often in 10^-2 ~ 10^-8g.3, the analysis accuracy at low concentration is high: the content of impurities in the range of 10-5% ~ 10-9% range, the relative error is as low as 1% ~ 10%.

What are the optical communication inspection instruments?

And the optical integrated index test system, which can test the insertion loss, return loss, polarization loss, RIPPLE, bandwidth, crosstalk and so on of the optical communication module.

Apparatus for measuring formaldehyde

It is best to add anti interference agents, because there are many impurities in the air, these impurities will interfere with the results of the test, resulting in the result is not allowed. The role of the anti interference agent is to eliminate the interference of these impurities. Therefore, it is necessary to select an anti interference detection kit.

How about doing sales of analytical instruments?

Sales analysis instrument is different from other popular products, it needs a rather professional product knowledge, so do the analysis premise equipment sales is a certain professional background, analytical instrument industry recruitment sales staff generally require professional background in science and engineering, chemical engineering or automation, bachelor degree or above, and not a professional marketing professional background. Therefore, good sales of analytical instruments, the first step is to have a very hard, very hard professional knowledge, a clear understanding of the performance and characteristics of their products, to understand the product can specifically solve what kind of problem.
