High-throughput analysis of polymers for benzene and volatile mosh and moah residues
20 Feb 2024Mineral 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 application note from Syft Technologies 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.

Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.

Gas Generators and AnalyzersGas generators are used for supplying or monitoring a regular flow of a high purity gas such as nitrogen, hydrogen or zero air for applications such as gas chromatography. Gas analyzers can be used in supply chain processes and laboratory experiments with portable analyzers for monitoring CO<sub>2</sub> and O<sub>2</sub> levels as well as trace gases. Regular flow can be produced with gas control modules and flow meters. Find the best gas generators and analyzers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Volatile Organic Compounds (VOCs)Volatile organic compounds (VOCs) are chemicals that have a low boiling point. Some VOCs are harmful to human health, whereas others can be used to determine the shelf-life of foods samples. Benzene
