Product Description
940b atmospheric volatile organic compounds (VOCs) preconcentrator, full touch screen operation, electric refrigeration instead of liquid nitrogen refrigeration, refrigeration temperature up to - 180 ℃, convenient maintenance, low operating cost, more easy to popularize. The preconcentrator adopts two-way sampling, two-way low-temperature water removal, double-channel ultra-low-temperature empty tube freezing to capture 102 kinds of VOCs, such as hydrocarbons, halogenated hydrocarbons, aldehydes and ketones. The pretreatment of water removal, concentration and focusing is completed at one time, and the capture efficiency / thermal desorption efficiency is higher than that of adsorption tube method. The service life of the air trap is long. 940b atmospheric volatile organic compounds (VOCs) preconcentrator can be combined with various types of GC and GC / MS analyzers.
Features

The capture efficiency and thermal desorption efficiency of air capillary column at - 150 ℃ are higher than those of adsorption tube method. Electric refrigeration can reach - 180 ℃ low temperature, instead of liquid nitrogen refrigeration, it is easy to operate, low cost and easy to be popularized. It is suitable for the concentration of various OCS, the separation of double chromatographic columns and the detection of double detectors. It has strong qualitative and quantitative functions. The concentrator has automatic back blowing purification function and strong anti-interference ability. The concentrator can be connected with sampling tank, sampling bag and other sampling equipment for off-line detection. The concentrator can be combined with various GC and GC / MS analyzers. The monitoring data will be uploaded to the database automatically. There are various forms of monitoring reports, including concentration data report, concentration time curve chart report, and various kinds of VOCs concentration percentage pie chart report.
