title: [Determination of arsenic content in Changtong oral liquid by inductively coupled plasma- mass spectrometry].
abstract: To determine arsenic content in Changtong oral liquid, inductively coupled plasma-mass spectrometry (ICP-MS) was employed, which generated linear calibration curves in the range of 5-25 ng/ml for As (r=0.9998). The average recovery of As was 98.94% (n=5, RSD=2.58%).
