This research aimed at developing an analysis method, which was optimized and validated to determine the content of mercury in skin lightening cream discovered in the market in Bandar Lampung, Indonesia, through the use of microwave plasma atomic emission spectroscopy (MP-AES). The optimization on the analysis method was conducted on pump rate, viewing position, and reductant concentration in order to obtain the highest mercury emission intensity, while the solution stability was optimized to know the stability of mercury in the solution. The result showed that the method developed had precision with a relative standard deviation of 2.67%, recovery value of 92.78%, and linearity with an r value of 0.993, respectively. The sensitivity of the instrument detection had a limit of analysis method detection and quantification of 0.59 and 1.98 µg/L, respectively. The results of the test of the lightening cream (8 of 16 samples) positively contained mercury in the range of 422.61–44,960.79 ng/g. Therefore the method of analysis developed may be used for routine analysis of chemicals in any cosmetics products.

Inductively coupled plasma-atomic emission spectroscopy (ICP-AES) is applied in the determination of 21 elements in primary, refined, and alloy aluminum. Rapid and reliable sample preparation procedures are developed. Spectral lines are selected after examination of experimental wavelength scans at each analyte wavelength. The limits of detection, background equivalent concentration, and analytical figures of merit are determined. For high silicon-containing aluminum, HF solutions were analyzed by employing an inert nebulizer utilizing polytetrafluoroethylene (PTFE) capillary tubes, a PTFE spray chamber, and an ICP torch with a graphite injector tube.
