Sequential Plasma Spectrometer
Catalog/Part Number:: ICPS-7000
Description
The ICP Emission Spectrometer having the following features is applied for a wide field of elemental analysis.
- High detecting sensitivity - ppb in detection limit
- Wide dynamic range
- Possibility of simalteneaus analysis
In the meantime, with the expansion of the application field, however, the following problems have emerged.
- A great deal of argon gas is consumed.
- A large spectrometer is required to minimize matrix effect.
- Complicacy in operation for analysis.
For the settlement of the above problems, advanced functions as mentioned below have been embodied in the compact body of the ICPS-7000/7510.
- Rapid analysis by ASD (Active Stabilized Direct Drive.)
- Reduced consumption of argon gas by half.
- An all-in-one type bench-top spectrometer.
- Easy and efficient operability under Windows(R).
The ICPS-7000/7510, which embodies a large capability in a compact body, characteristic of space saving and energy saving, is an instrument commensurate with the 21st century.
