Usage:
The ICP Emission Spectrometer is an automated analytical instrument for analyzing microelements and trace elements. It has a wide range of applications, and can be used in the fields of environmental monitoring, chemicals, geology, agriculture, pharmaceuticals, biology, foodstuffs, metallurgy and many others.
Features:
- High sensitivity, low detection limit of 10-8~10-10 g/ml.
- High precision with RSD less than 1.5%.
- Minimal matrix effect.
- Wide analyzable concentration range of 4~5 orders of magnitude.
- Simultaneous analysis of multi-elements
- Dynamic background correction to eliminate spectral interference.
- Integrated data collection control board is located inside the computer, ensuring strong resistance to interference.
