“…Liew reported a fully automated sampling-sample preparationanalysis platform using a modified vial, peristaltic pump, mini-scale liquid−liquid extraction, evaporation, and GC−MS to measure six UV filters. 200 LODs ranged from 0.6 to 9.7 ng/ L, recoveries ranged from 62 to 80.7%, and good linearity was observed for benzhydrol, 2-ethylhexyl salicylate, homosalate, 2hydroxy-methoxybenzophenone, 3-(4′-methylbenzylidene)camphor, and benzophenone. This new method was subsequently demonstrated on swimming pool water, where recoveries ranged from 85.4 to 118.2%, and it was recommended for onsite water analysis.…”
