摘要：

In arsenic speciation with the use of coupled techniques (separation-atomic spectroscopic detection) the generation of arsines improves sensitivity. This article focuses on the incorporation of on-line UV photolysis to transform arsenobetaine and arsenocholine into simpler species which are able to generate arsines. The couplings of LC-UV-HG-ICP-OES (liquid chromatography-photolysis-hydride generation-inductively coupled plasma optical emission spectroscopy) or LC-UV-HG-QCAAS (liquid chromatography-photolysis-hydride generation-quartz cuvette atomic absorption spectroscopy) are proposed and were used to analyze Dorm-1 dogfish muscle Certified Reference Material with total arsenic certified. The results are compared with those reported in the literature by using LC-ICP-MS (liquid chromatography-inductively coupled plasma mass spectrometry).
