GB/T 29660-2013 in English

《GB/T 29660-2013化妆品中总铬含量的测定》由TC257（全国香料香精化妆品标准化技术委员会）归口，主管部门为中国轻工业联合会。
本标准规定了用火焰原子吸收分光光度法、电感耦合等离子体质谱法测定化妆品中总铬含量的方法。
本标准适用于化妆品中总铬含量的测定。当称样量为1g时,火焰原子吸收分光光度法检出限为0.25mg/kg,定量限为0.83 mg/kg;电感耦合等离子体质谱法检出限为0.005 mg/kg,定量限为0.015mg/kg。

Scope

This standard specifies the method for the determination of total chromium content in cosmetics by flame atomic absorption spectrophotometry and inductively coupled plasma mass spectrometry. This standard applies to the determination of total chromium content in cosmetics. When the sample weight was 1 g, the detection limit of flame atomic absorption spectrophotometry was 0.25 mg/kg, and the limit of quantification was 0.83 mg/kg; the detection limit of inductively coupled plasma mass spectrometry was 0.005 mg/kg, and the limit of quantification was 0.015 mg/kg.
