Application Note: Direct Hg analysis in cosmetics sample in compliance with ISO 23674 using Milestone DMA-80 evo
28 February 2024

The International Organisation for Standardisation (ISO) has developed a method for detecting trace amounts of mercury in cosmetics which involves the direct analysis of cosmetic samples without the need for sample preparation. It allows the direct quantification of the total amount of mercury in both solid and liquid cosmetic samples. This has led to the introduction of ISO 23674, which focuses on direct mercury analysis techniques. In this application note, discover the Milestone DMA-80 evo, a mercury analyzer of solid, liquid and gas samples. Analysis takes five minutes and no sample preparation is required. The DMA-80 evo provides direct temperature control of the sample, and temperature is monitored at a rate of 20 times per second and a PID control adjusts the temperature according to set parameters resulting in control of exothermic reactions.
