ICP-MS-2000 inductively coupled plasma mass spectrometer

Introduction
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 , very low detection limit , a very wide dynamic range , simple lines , less interference , high precision, fast speed , can provide isotopic analysis .

This product is the first domestic industrial inductively coupled plasma mass spectrometer , the instrument of the 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
Injection System: open- injection system architecture, using 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 , security itself 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 method .
