ICP-MS-2000 Inductively Coupled Plasma Mass Spectrometer
Inductively coupled plasma mass spectrometer ( abbreviated ICP-MS), was developed in the 1980s, a new micro ( 10-6 ), trace ( 10-9 ), and ultra-trace ( 10-12 ) elemental analysis technology. Most of the periodic table of elements can be determined, a very low detection limit, a very wide dynamic range, simple lines, less interference, high precision, and fast speed, can provide isotopic analysis.
This product is the first domestic industrial inductively coupled plasma mass spectrometer, the instrument of performance reached the national standard, to meet the needs of user applications, cost-effective; the products are mainly used in environmental, food, semiconductor, medical and physiological analysis, nuclear industrial fields.
Features of ICP-MS-2000 Inductively Coupled Plasma Mass Spectrometer
Injection System: open-injection system architecture, using a nebulizer externally mounted, self-positioning, without adjustment.
Torch position adjustment system: full control of the computer x, y, z torch accurate three-dimensional position, all adjustment parameters stored in the analysis. Plasma shielding technology: greatly improved sensitivity, improve the detection limit of the number of elements of low quality, to ppt level
Activities valves: computer control, protection equipment vacuum, easy disassembly and cleaning sampling and skimmer cones work in the vacuum system.
Ion lens system: with a high-efficiency hexapole ion guide system, ion transmission efficiency to get the best quality in the whole range of ion focusing automatic tuning process, the vacuum chamber of the lens using asymmetric installation, easy disassembly positioning.
Detector: ETP dual mode detector, without digital/analog switch.
The new vacuum chamber structure: the cavity without any wires, each component asymmetric installation, and plug-in installation.
Power protection systems: power outage occurred in the accident, and security itself was off without damaging the instrument system.
Software: Provides automatic control instruments and their accessories abilities, software encompasses a variety of analytical methods, including special isotope ratio determination and isotope dilution methods.
