Activated carbon for measuring xylene in ambient air and exhaust gas
Activated carbon measurement of xylene in ambient air and exhaust gas Details:

Activated carbon sampling tube:
Specifications: 6 * 80mm100 / 50mg, 6 * 120mm100 / 50mg, 6 * 150mm100 / 50mg, 6 * 180mm100 / 50mg, 1/4 * 80MM
Solvent desorption type: CS2 / carbon disulfide
Application: Ambient air and exhaust gas Determination of xylene Activated carbon adsorption / carbon disulfide analysis-gas chromatography

Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd. established capillary column gas chromatography for the determination of xylene in ambient air and exhaust gas. Xylene was detected by activated carbon adsorption / carbon disulfide desorption, HH-WAX capillary column separation, and hydrogen flame ionization detector. The results show that the correlation coefficients of the standard curves for the determination of 1,3,5-trimethylbenzene, 1,2,4-trimethylbenzene, and 1,2,3-trimethylbenzene are 0.9999; When the injection volume is 2.0 μL, the method precision is 0.24% -0.39%, the standard recovery is 96.7% -108.3%, and the detection limit of the 1,3,5-trimethylbenzene method is 8.4 × 10 ^ -4mg · m ^ -3,1,2,4-xylene method detection limit is 6.9 × 10 ^ -4mg · m ^ -3,1,2,3-xylene method detection limit is 7.5 × 10 ^ -4mg · m ^ -3. Tests show that the method can effectively remove the influence of interferences after optimizing the performance. The collected samples can be stored for 7 d in a low temperature environment of 4 ° C.
