Product description, technical parameters and configuration

Inductively coupled plasma mass spectrometry (ICP-MS), a new trace (10-6), trace (10-9), and ultratrace (10-12) elemental analysis developed in the 1980s technology. ICP-MS can determine most of the elements of the periodic table of elements, and has extremely low detection limits, a very wide dynamic linear range, simple spectral lines, less interference, high precision, fast analysis and other performance advantages.

The ICP-MS2000 series is an independently researched and developed product of Tianrui. Currently, there are two models of ICP-MS2000B and ICP-MS2000E. The performance of ICP-MS2000 series instruments is superior to the national standard, fully meets the needs of users in different industries, and is cost-effective. At present, the product is mainly used in the fields of environment, food, semiconductor, medicine and physiology analysis, and nuclear industry.

The ICP-MS2000 series has excellent instrument performance and efficient analysis. The daily running consumption equipment of the instrument is independently developed and cost-effective. At the same time, we provide quality after-sales service, 10 minutes response, on-site service within 48 hours, customer service center to track services at any time, to ensure the quality of service.

ICP-MS 2000B Features

Robust solid-state power supply ensures that the instrument can operate in multiple modes (eg, normal mode, cold plasma mode), and allows multiple modes to run in the same method, saving a lot of analysis time and facilitating research.

Advanced plasma shielding technology greatly improves the sensitivity of the instrument and improves the detection limit of low-quality elements. To ensure applications such as cold plasma mode, the detection limit of easily ionizable elements such as K, Na, Ca, Mg, and Fe can be reduced to ng.L-1 without the use of collision/reaction gas.

2. ICP-MS 2000E Features

Inverted plasma uses push-pull complementary technology to eliminate the potential difference existing in the traditional plasma, eliminates the secondary discharge phenomenon of the plasma, and produces lower and narrower ion energy diffusion, which greatly improves the sensitivity of the instrument. The robust variable-frequency power system ensures that the instrument can run multiple modes (such as normal mode, collision response mode, and cold plasma mode), and allows multiple modes to run in the same method, saving a lot of analysis time and facilitating research.

The hexapole collision reaction cell is configured to use the (H2+He) mixture to eliminate the interference of ArCl and CaCl to As in the KED mode; at the same time, Ar, ArH, ArO, etc. can be eliminated without the need to switch gas and other tedious operations. K, Ca, Fe interference.

250-bit automatic sampler is configured, Ethernet communication is imported, positioning accuracy is less than 500μm.

ICP-2000 series inductively coupled plasma mass spectrometer also has the following outstanding performance and characteristics:

Plasma position XYZ three-dimensional computer-controlled full-automatic precision adjustment, the adjustment amplitude is accurate to step 0.1mm;

The torch is a one-piece quartz concentric torch, avoiding the cumbersome operation of the disassembled rectangular tube and the damage that may result;
