ICP-OES Spectrometer - PLASMA 2000

The echelle grating and crossed prism dispersion structure in combination with large-area CCDs for simultaneous display of all spectral lines of single exposure and “full-spectrum transient direct reading”.

The programmable output power program has an automatic real-time tuning function for continuous 1W adjustment within 800-1600W, with a stability of above 0.1%.

Application engineers jointed in the software design team to provide tailored operational software for users.

The Principle of Instrument

Operating Principle

The test sample is first changed into aerosol in a nebulizer and then enters the central plasma passage of the quartz torch, etc. The light excited by heating from the light source is split by a prism and echelle grating to form characteristic spectral lines of elements on the CCD detector. A spectrogram is generated after processed in the circuit. The element concentrations are determined by means of computer data processing.

Light source

The efficient solid-state RF generator is compact in size and has high efficiency.

Oscillation frequency: 27.12MHz;Output power: 800-1600W (with real-time tuning capable of continuous adjustment by 1W,

with stability better than 0.1%).

The torch position can be adjusted electrically, and the software has the automatic torch position optimization function.

The electrical control system is modularized and can provide high-performance CAN industrial field interfaces to ensure efficient and reliable communication.

The system operating parameters are monitored in real time; and the system is provided with built-in protection logic for interlocking protection of gas, water, temperature, and door switch, etc.
