Ambient TVOC and Benzene Analysis Chromatograph, Shanghai HengPing Instrument and meter Co.,Ltd. (CAT#: STEM-AI-0414-YJL)

Ambient TVOC and Benzene Analysis Chromatograph, model STEM-AI-0414-YJL is manufactured by Shanghai HengPing Instrument and meter Co.,Ltd. Shanghai Kechuang Chromatography Instrument Co., Ltd. has accumulated more than ten years of experience in ambient air analysis gas chromatograph, and has continuously improved and optimized the instrument. The adsorption tube adopts the U-shaped tube of science and technology technology, which can be directly inserted into the heating block for rapid and uniform heating, and the desorption effect is good.
Customers can choose one thermal desorption or two thermal desorption injection mode. The primary thermal desorption is the direct desorption of the sample through the adsorption tube; the secondary thermal desorption is the adsorption of the adsorption tube, the thermal desorption and injection after the secondary cold focusing, with high recovery rate, good component peak shape and high separation efficiency.
The HL-800 secondary thermal desorption instrument produced by the company can be used with various types of domestic and imported gas chromatographs or GC-MS instruments, and can also be modified to the original Kechuang gas chromatograph.

LCD screen or 5.7-inch color touch screen;
All microcomputer computer counter control system, a single computer can control less than 253 chromatographs, with 7 channels of temperature control; 8 channels of external event time programs;
The instrument has a built-in indoor environmental monitoring (TVOC) chromatographic workstation, with intelligent peak identification/automatic processing, multi-channel spectrum integration and exchange, automatic calculation of unknown peak content with toluene, and automatic conversion of sampling volume to standard state according to ambient temperature and pressure. And automatically calculate the content of each component and the whole in the unit sampling volume, and can also deduct the peak area of ​​each component in the solvent and the content of each component in the outdoor air sample to obtain the final result, etc.;
The instrument adopts RJ45 network cable interface, signal output, control and acquisition are simple and convenient, which can realize remote control of the instrument and remote data transmission processing and supervision. It can be connected to the supervisor of the unit and the superior supervisor, which is convenient for supervisors to implement supervision;
Large-capacity column oven with automatic back door, 8-step temperature programming, and control function of column oven near room temperature (5°C above room temperature);
It has the function of fault self-diagnosis, which can display the fault location and nature; it has the function of over-temperature protection, and the heating will automatically stop if the temperature of any route exceeds the set temperature.
