Inductively Coupled Plasma Optical Emission Spectrometer ICP-6800
Main features
Performance stability:The use of all-solid-state rf power supply, with small size, high
efficiency, stable output power, with a variety of protection
functions and many other advantages, the load using fully automatic
matching technology, matching speed, improve the efficiency of the
use of power supply and the stability of the instrument, and make
the whole ignition process simple and convenient. |
Injection automation:Adopting four-channel automatic design, the rotational speed can be
set up according to the test demand to adjust the flow rate,
carrier gas, plasma gas, auxiliary gas are all controlled by
advanced mass flow controller, at the same time can be equipped
with imported high salt nebulizer, imported hydrofluoric nebulizer
and so on to meet the customer's various test needs. |
Precision analysis:The middle step grating prism cross dispersion mode is adopted,
there is no moving optical element, the ultra low stray light
design is combined with the unique optical design, nitrogen
distributed blowing, imported optical elements, intelligent and
accurate automatic wavelength calibration algorithm. |
Quick test:In American thermoelectric CID detector, the 160-1000nm range is
continuously covered, and the intensity integral values of all
analytical spectral lines are read out at one exposure to speed up
the analysis |
