Analysis of Aromatic Hydrocarbons in Workplace Air by Gas ChromatographyProduct Introduction:

【 Analysis Principle 】Aromatic hydrocarbon compounds such as benzene, toluene, xylene, ethylbenzene, styrene, ethylbenzene, and isopropylbenzene are commonly used organic solvents in spray painting, printing, and other work, and often coexist at the same time. Therefore, when detecting toxic substances in the workplace, the above compounds coexist on activated carbon tubes, and appropriate analysis conditions are selected for simultaneous analysis and determination. This method selected DB-VRX capillary gas chromatography for rapid determination of the above-mentioned aromatic compounds. This method has the characteristics of short analysis time and good separation effect.

【 Installation Requirements 】 Basic Operating Requirements for Instruments

1Power requirements:

Voltage:220±10%

Frequency:50±0.5Hz

Power:≥3000W

Grounding requirement resistance: ＜0.1Ω

2Gas source requirements:

Nitrogen:99.995%

Hydrogen gas:99.995%

Air: dry and oil-free

3Hydrogen flame ionization detector（FID）Basic operational requirements

Carrier gas: internet traffic50ml/min(30—80 ml/min)

Hydrogen gas: internet traffic30ml/min(25—40 ml/min)..

air internet traffic350 ml/min(250—500 ml/min).

4Thermal conductivity pool detector（TCD）Basic operational requirements

Before starting up, the carrier gas should be supplied first30min, traffic50ml/minThen turn on the machine and heat it up

Flow correction, two outlet flow deviation≤1%

According to the analysis requirements, set the size of the bridge flow value

When using nitrogen as the carrier gas, the bridge flow should be appropriately reduced compared to hydrogen as the carrier gas

5.Special reminder: First supply the carrier gas, then turn on the machine to increase the temperature!
