Domestic methane non methane total hydrocarbon analyzer

Shanghai Xuansheng ScienceThe indoor air pollution detection TVOC analysis solution provided by the Institute of Instrument Application is based on the requirements of the "Code for Indoor Environmental Pollution Control of Civil Building Engineering" issued by the Ministry of Construction. It uses gas chromatography to quantitatively detect the content of indoor air pollution detection TVOC and benzene.

A hydrogen flame ionization detector is a device that uses the heat generated by a hydrogen air flame to ignite a sample and a carrier gas. The hydrogen air flame itself produces very few ions, but when organic matter burns on the hydrogen flame, more ions are produced. A collection electrode is installed near the hydrogen flame. Under the action of the polarization voltage on the collecting electrode, positively charged ions and electrons will move towards both ends to form ion streams. The size of the ion flow is proportional to the amount of burning sample in the flame, and the ion flow is converted into a digital signal by an electrostatic meter.In addition to formic acid and formaldehyde,FIDIt responds to almost all organic compounds and is the most widely used gas phase detector.

Requirements for laboratory installation conditions:

Power supply voltage: 220V~± 22V, 50Hz ± 0.5Hz

Total power of the instrument: ≤ 2000W

Environmental temperature:+ 5℃～＋35℃

Relative humidity:< 85%

Attention: There should be no corrosive gases or electric or magnetic fields that affect the normal operation of the instrument in the placement location. The instrument placement workbench should be stable and free from vibration.
