ICP-MS 2000 is the first industrialized inductively coupled plasma mass spectrometer in China with its performance reaching China national standard.
Configurations:
Inlet:Open modular sample introduction system with externally mounted atomizer is able to locate automatically
Torch Alignment:X,Y and Z axes are accurately PC-controlled,with all the adjusted parameters saved in analysis methods
Advanced plasma shielding:greatly improving sensitivity and limits of detection of light elements(ppm level)
Valve gate:PC-controlled valve to retain vacuum,facilitate assembly,disassembly and cleaning of the sampling and skimmer cones when vacuum system is on
Ion lens: Hexapole ion guide can transmit ions in full mass range efficiently with automatic ion focusing and tuning
Detector:ETP dual-mode detector,discrete dynode electron multiplier
Vacuum chamber: wireless connection
Power-off protection:automatically shut down to protect the system in case of unexpected power failure
Software:automatic control of instrument and accessories,( Windows 2000/XP/vista/window7,both 32 and 64 bit are ok), professional system
