Determination of benzene series in drinking water and water source by TP6000 all-around headspace sampler-capillary column gas chromatography
Determination of benzene, toluene, o-xylene, m-xylene, p-xylene and benzene in domestic drinking water and its water sources according to the headspace-capillary column gas chromatography specified in the national standard "Sanitary Standards for Drinking Water" (GB5749-2006) The method of ethylene and cumene, through the use of Beijing North
The TP-6000 all-around headspace sampler developed and produced by Fentianpu Instrument Technology Co., Ltd. conducted experiments on these regulations. The experimental results show that: 8 components are measured within 11 minutes and have a good separation effect; different components are in ( 1 ~ 100） Comparable in ug / L concentration range
Good linear relationship, the correlation coefficient (r) is 0.99 ~ 0.999; the minimum detection limits are: benzene 0.7ug / L; toluene 1ug / L; ethylbenzene 2ug / L; m- and p-xylene 1ug / L; styrene 2ug / L; o-xylene 3ug / L; cumene 3ug / L. Conclusion: TP-6000 all-around headspace
The sampler is heated than the conventional water bath and then sampled and analyzed: the operation has a high degree of automation, simple and convenient, good reproducibility, improved sensitivity, and is suitable for detecting the content of benzene series in water.
