High-Throughput Analysis of MOSH / MOAH and Benzene in Consumer Packaging


Mineral oil hydrocarbons (MOH) are widely used as lubricants and may contain carcinogenic and mutagenic impurities. Hence food safety authorities require that ingredients, finished products, and packaging materials be tested. Comprehensive analysis of MOH utilizes a combined liquid and gas chromatography procedure, which is very challenging and time consuming. This article demonstrates that automated headspace-SIFT-MS analysis has potential to screen larger numbers of packaging samples – over 220 per day – for the volatile MOH fraction, providing a rapid indication of packaging material contamination. Moreover, SIFT-MS can simultaneously quantifies benzene contamination – addressing this recently identified need for personal care products (PCPs).
