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 (down to ppt 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. Asymmetrical installed lens in vacuum chamber are easy to assemble and disassemble.
Detector: ETP dual-mode detector, discrete dynode electron multiplier, no need to switch on digital/analog modes.
Vacuum chamber: no wire connection. Each module adopts asymmetric and plug-in set.
Power-off protection: automatically shut down to protect the system in case of unexpected power failure.
Software: providing automatic control of instrument and accessories. Windows ***0/XP/vista/win7(*2 bit or *4 bit) professional operation system.

Application

1.Environmental protection: drinking water, seawater, water resources, food, hygiene and disease control, goods inspection, etc.
2.Semiconductor industry: high pure metals, high pure reagents, ultratrace impurities of Si chips, photoresists, etc.
3.Pharmaceutical and physiological analysis: medical research on hair, blood, serum, urine, biological tissues etc., for example, testing Pb in whole blood.
4.Nuclear industry: nuclear fuel radioisotopes, pollution of primary cooling water etc.
5.Other fields: chemical industry, petrochemical industry, geology, etc.
