Mass spectrometer with QAS100 mobile system to detect gas field


For people to walk the pipeline construction and installation, about 200 meters of pipe buried in the 40 - meter deep underground. Suddenly the front of the workers in the pipeline choking sense of thistle. Whether an engineer brigade, or the industrial engineer glanced Review Committee, or the amount of domestic chemical experiments in the field who can give it the gas composition and changes with time information quickly and reliably, and in such conditions they can not be used under the experimental car. In this case, the most rapid and simple method is: 200 meters through the thistle tube to QAS100 handling front end. Measuring head on the ground 2 meters away from the place, in different ventilation conditions were measured. Changes in the composition of these gases is very fast, so long as there is a short interruption of ventilation, can lead to death of workers in the region (Figure 5) In addition to 0z, Nz, CO: and methane, can be detected in the concentration range Granting that the presence of other harmful gases. Figure 5, the change of gas concentration with time (references omitted) Note l Leybold company recently developed a mobile quadrupole mass spectrometer system,[link widoczny dla zalogowanych], including the four-pole system, vacuum system, sampling devices and intelligent data system, including touch ~ the analysis system weighs just 50 kilograms, can be placed in the car trunk of a real scene. The instrument's mass range i ~ 99am \amplifier, the minimum detectable concentration of 10ppm, with a DC amplifier to lppm, thanks to 501 / s of small molecular pump, mooring just five minutes and then start the qualitative analysis, 2 elbow after small quantitative analysis, direct When the injection pressure should be less than 2xi0 a mbar, capillary injection system through the injection pressure range of 10 ~ - 1000mbar, the total power of 32O-watt power supply, standby power can drive. QAS100 system can be traced back home the following: 1. gas concentration quantitative analysis: can volume percentage. This gas mixture is given directly in the form, such as CH., N / cO, NO., O, and Af and other concentrations. This model applies special shot: * for the control of soil pollution and Garbage piled up. to gas analysis, the internal combustion engine exhaust gas analysis J * biotechnology fermentation process control. 2. vacuum system self-test: a typical residual gas can collect {agriculture; the relative content and the total pressure data book, Lei system which can assess the state of the vacuum, to ensure that users can get an accurate quantitative analysis of Bute. 3. leak detection: the use of sniffer leak detection,[link widoczny dla zalogowanych], can be recorded, such as SF, r, or transient changes in Freon, solid and able to detect The pressurized system components leak location. 4. Direct Mode: enables users to directly use mass spectrometry for each function. This instrument has been used in chemical plant on-site leak detection; laboratory, workshop monitoring of harmful gases wine, and directly identify the source of harmful gases,[link widoczny dla zalogowanych], the earth pollution, toxic and hazardous explosive landfill gas monitoring, vehicle exhaust monitoring guillotine, stack gas monitoring, and a variety of environmental applications, is a broad prospect Attention quadrupole mass spectrometry instrument site. In order to further understand the effect of its application,[link widoczny dla zalogowanych], I get a company through the application of Leybold report,[link widoczny dla zalogowanych], now translated for the parties of its reference. # Health beam re-argue the letter translated from Leybold Company Doctor \VAKUUMTECHNIK \photosynthesis. fruit yeast photosynthesis of its leaves can be outside, it has another system, using this system for the intake of heavy j-off of fixed carbon from the mitochondrial respiratory COz. phosphoenolpyruvate carboxyl group in enzyme (PEPC) under the ship, a process that produces malate, and performance-based play by the cell fluid HCO. / co: and to regulate the concentration of malate. malate to malic acid stored in liquid form cell, the formation of a major carbon pool and the potential for respiratory substrate. PEPC in Apple proved to be a low Michaelis constant of the enzyme with an effective form, that is five I = O.I} 9mol ・ m'PEP and O .2 tool ・ m one.
