Laboratory equipment during the test
- Verification is a verification, and period verification is a period check. The general requirements for laboratory ability shall be subject to the period verification during the 1 test cycles, that is to say, verification must be carried out, but also to be checked during the period.s
Chemical composition analyzer
- Chemical composition analysis is relatively simple for inorganic salts, some glass instruments are almost enough, and atomic absorption spectrometers can also be used;s
What is the principle that the signal bandwidth of the instrument is much higher than the sampling rate?
- The bandwidth of the instrument reflects only the hardware characteristics of the instruments
What are the chemical analysis instruments?
- Instrumental analysis (modern analysis or physical analysis): a method of analysis based on physical or physical and chemical properties of matter. This kind of method is usually measured by light, electricity, magnetic, acoustic, thermal and other physical quantities and the results of the analysis, and the measurement of these quantities, generally use more complex or special equipment, so called "instrument analysis". In addition to qualitative and quantitative analysis, instrumental analysis can be used in the analysis of structures, valence states, state analysis, micro and thin-layer analyses, micro and ultra trace analysis, etc., and is the direction of the development of analytical chemistry.s
Which brand is good for chemical analysis instruments?
- In addition, when the glutaraldehyde storage time is too long, the pH value will be reduced, the color yellow, the fixed potency will be greatly reduced. If the glutaraldehyde pH value drops below 3.5 or contains other impurities, it must be purified before it can be used. Glutaraldehyde has a hardening effect on the skin, but it is less volatile than formaldehyde. It is best to operate in a fume hood.s
About chromatographic instruments
- When the gas sample is used, the sample is injected directly; when the liquid phase is used, the sample is hit into the gasification chamber and then flows into the chromatographic column. The two column is gas phase in the chromatographic column.s
How to choose the coal analysis instrument?
- 1., the quality of good or bad, depending on the mouth that useless, the most important thing is the experience of the results (other customers use the product evaluation), followed by manufacturers of product quality assurance system (product quality control process);2. service is good or bad, manufacturers commitment to service is very important.3., "cheap goods, good goods are not cheap" - although not very accurate, but most of the time is the truth of the truth!s
Which is more promising for the sale of medical devices and analytical instruments?
- In sales, it's difficult to sell the hospital. You can't get close to the purchasing leader of the hospital unless you have a strong hospital background. Otherwise, it will be difficult.s
