China's environmental site inspection equipment inventory

In order to enhance the awareness of environmental emergency monitoring, improve environmental emergency monitoring capabilities, strengthen the environmental emergency monitoring team, strengthen the environmental monitoring departments of provinces, cities, and cities, as well as monitor emergency response, supervision, information, education, etc. The joint emergency monitoring of emergency environmental incidents and environmental emergency monitoring have also been gradually recognized by everyone.

The portable GC/MS is a precision instrument suitable for environmental emergency monitoring. It is mainly used for the qualitative and quantitative detection of volatile semi-volatile organic pollutants in the atmosphere, water, and soil. Provide reliable decision-making basis for emergency environmental accidents on site. Its greatest advantage is that it can detect and report test reports on the spot, shorten the time, reduce costs, and make quick assessments for sausage emergency selection. The following Xiaobian introduces three mainstream portable GC/MS instruments in China.

TORIONTRIDION-9 Profile:

The TRIDIONTM-9GC-TMS from Shenzhen Railay Technology Development Co., Ltd. is TORION's world's most lightweight, portable and portable capillary gas chromatography mass spectrometer. The TRIDION-9 portable gas chromatography mass spectrometer integrates fast low-thermal capillary gas chromatography and miniature circular ion trap (patented) mass spectrometry. It is fast, reliable, and easy to operate.

The TRIDION-9 uses a very small internal diameter, low thermal mass capillary GC to provide a more efficient and faster solution for the separation of chemicals.

The rapid program temperature system allows the analysis time of the compound to be less than 3 minutes.

The circular ion trap mass spectrometer can detect a wider range of mass numbers, featuring high sensitivity and selectivity.

The color touch screen and simple operation buttons make the TRIDION-9 easier to operate.

Portable can be applied to any site, 5 minutes to analyze a sample, so as to meet the emergency detection of various emergency situations at the scene.

InficonHapsiteER:

Infracore's Hapsite series of low-heat-capacity on-column heated gas chromatography-mass spectrometry systems and its data processing workstations are the earliest portable environmental analysis and emergency detection solutions for entering the Chinese market. The solution has its own laboratory. Analyze the level of on-site inspection capabilities, truly achieve qualitative and quantitative analysis at the sampling point in real time, and provide strong technical support for users to make emergency response and key decisions.

The low-heat-capacity column heating technology combined with the miniaturization design of the quadrupole mass spectrometer can effectively reduce the power consumption of the instrument while satisfying the analysis ability. NEG vacuum technology ensures the vacuum requirements of mass spectrometry in portable and emergency use.

Quadrupole mass spectrometry provides full-scan and ion-selection modes to achieve laboratory mass spectrometry sensitivity levels.

Provides two detection modes. In emergency mode, direct mass spectrometry can be performed to make emergency response to the most important pollutants at the fastest speed; in the analysis mode, volatile and semi-volatile substances can be completed within several minutes. Comprehensive analysis can reach the analysis level of laboratory temperament system.

Fully sealed design, the whole machine puts water in dust and protects the normal work in the harsh environment of the field.

Concentration Technology Mars-400 Profile:

Mars-400 combines the low-capacity gas chromatography technology with ion trap mass spectrometry to give full play to the advantages of the former in mixture separation, accurate quantification, and the latter in qualitative detection and structural analysis, and become an integral part of emergency monitoring. Analytical weapon. Compared with conventional detection instruments, this portable GC-MS analyzer features fast analysis, accurate accuracy, lightweight and portable, and high detection sensitivity.

The Mars-400 uses low heat capacity gas chromatography (TM-GC) to provide faster temperature increase/decrease rate than traditional oven heating methods, shortening the instrument's single analysis cycle to more than ten minutes, and greatly accelerating on-site emergency response. reaction speed.

With its highly integrated and modular design concept, the Mars-400's main unit is comparable to a projector and weighs only 14kg. It is a truly portable analyzer that can be carried around.

The patented pulsed internal ion source technology and dynamic adsorption-thermal analysis technology enable the instrument to handle trace analysis of ppb and even lower concentrations.

The summary of on-site emergency test equipment requirements:

1, portable. Small size and light weight. Emergency testers can quickly move the instrument to the emergency site.

2, fast. The boot should be quick, the sample must be fast, and the result should be quick. Emergency testers can get reliable in the shortest time

The data provided the basis for the emergency treatment decision-making at the site and minimized the loss and damage of the emergency.

3, accurate. The measured data is reliable and accurate. Can be used as the basis for on-site decision making, and the false alarm rate is low.

4, durable. The shockproof performance is good, can guarantee the instrument is carried to the scene and can finish testing normally.

5, easy to use. The operation is simple, preferably one-button operation.
