This method is based on the decomposition reaction of trichloroacetic acid under high\u2010temperature conditions. The carbon dioxide and chloroform formed from the decomposition reaction can be respectively detected by the thermal conductivity detection HS\u2010GC and flame ionization detection HS\u2010GC. The reaction can be completed in 60\u2009min at 90\u00b0C. This method was used to quantify 25 different human urine samples, which had a range of trichloroacetic acid from 0.52 to 3.47\u2009mg\/L. It also utilized two different detectors, the thermal conductivity detector and the flame ionization detector. The present reaction HS\u2010GC method is accurate, reliable and well suitable for batch detection of trichloroacetic acid in human urine.<\/jats:p>","DOI":"10.1002\/bmc.4288","type":"journal-article","created":{"date-parts":[[2018,5,16]],"date-time":"2018-05-16T15:10:09Z","timestamp":1526483409000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Utilizing
