How do you decide which instrument analysis method can be used to solve an analysis problem?
- 1. Ion chromatography is suitable for quantitative analysis of anions;2. Atomic absorption spectrometry is suitable for quantitative analysis of metal ions;3. Polarographic analysis is suitable for quantitative analysis of metal ions;4. Gas chromatography is suitable for quantitative analysis of organic compounds;s
What is the difference between a vector network analyzer and a scalar network analyzer?
- In the network division, the vector has more phase angles, and has the imaginary part of the real part, but the scalar can only measure the modulus of the reflection coefficient.s
Photoelectric colorimeter - spectrophotometer - urine analyzer - Automatic Biochemistry Analyzer - same and different points of enzyme analyzer
- Different points: photoelectric colorimeter, urine analysis, enzyme labeling instrument using filters as optical elements, its wavelength selection range is limited. Spectrophotometer, automatic biochemical analyzer using a prism or grating as light splitting element, can obtain continuous and wide wavelength. Urine analyzer in urine reagent strip for monochromatic light absorption and light intensity to test the size of anti content urine components.s
What are the chemical analysis instruments?
- 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.s
Instrument features of ICP-AES analyzer
- The analysis accuracy and precision are higherICP-AES method is a small interference in various analysis methods. Under normal circumstances, its relative standard deviation is <10%. When the concentration of analyte exceeds 100 times, the relative standard deviation is <1%s
Apparatus for measuring formaldehyde
- Make sure you buy Glass bottles. Many small manufacturers use plastic bottles to test liquid, because plastic bottles are cheap. However, the long time contact between the plastic component and the detection solution will result in reaction, which will have a bad effect on the test result. The glass bottle is much better now, will not leak, is the high cost of a point.s
Could you tell me the error range of carbon and sulfur analysis?
- Measurement range of HCS-500 type infrared carbon sulfur analyzer: HCS-500 type infrared carbon sulfur analyzer is the pyroelectric sensor as the core, by high frequency induction combustion furnace and intelligent microcomputer control system composed of infrared analysis instrument. The analysis software is based on WINDOWS XP operating platform, which has standard WINDOWS, Chinese operation interface and user-friendly human-computer interaction function. Mainly used in metallurgy, machinery, commodity inspection, scientific research, chemical and other industries in the ferrous metals, non-ferrous metals, rare earth metals, minerals, minerals, ceramics and other substances in the analysis of carbon and sulfur content.s
What's the quality of the glass instruments of Shu Niu?
- Good quality, the laboratory is often used in his family's productss
