说明

一般描述

乙苯是无色液体,具有芳香气味。广泛用于生产苯乙烯,也经常作为溶剂。它不溶于水。
 

应用

乙苯可作为分析标准品,通过各种色谱技术测定油漆、机油、生物样品、水和空气样品中的分析物。[1][2][3][4][5]可作为标准品加入泵油,形成优良的固相微萃取 (SPME) 标准发生器。[6]
The analytical standard can also be used in the following:
  • Construction of a multi-bed needle-trap device for sample treatment of volatile organic compounds in indoor air samples collected from an office, corridor, and a laboratory, for their analysis by gas chromatography-flame ionization detector (GC-FID)
  • Development of a Carbotrap B sorbent-packed needle-trap device for the sampling of benzene, toluene, ethylbenzene, and xylene isomers from air samples for their analysis by gas chromatography-mass spectrometry (GC-MS)
  • Simultaneous detection and quantification of 14 volatile organic compounds (VOCs) from 283 flavored refill liquids, 21 nicotine refill liquids, and 12 cartridges of electronic cigarettes by headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS)
  • GC-MS detection of 11 VOCs following their extraction using a dynamic headspace needle-trap device (D-HS-NTD) having ZIF-8-derived nanoporous carbon (ZIF-8-NPC) as an adsorbent, from 20 pen ink samples
  • Determination of seven volatile organic compounds in the surgically resected colonic tissue samples of colorectal cancer patients by gas chromatography-mass spectrometry (GC-MS) following their extraction by headspace- and direct injection- based solid phase microextraction (SPME)
