GC/MS CI , CI/NCI and SMCI Measurement
CI is a softer ionization method than EI, fragmentation is less likely to occur, so molecular weight information is more readily obtained. Negative chemical ionization (NCI) or negative ion chemical ionization (NICI) enables selectively measuring, with ultra high sensitivity, chemical substances with an electron affinity, such as chlorine-based compounds.

Solutions for Analysis of Ethylene Oxide and 2-Chloroethanol in Food
Even though Ethylene oxide (EtO / EO) is well-known to be a toxic compound with carcinogenic and mutagenic concerns, it has been widely used for fumigation in the food industry because it effectively reduces or eliminates microbiological contamination with bacteria/fungi. The recent recall of food products exported to the EU due to non-compliance with EU regulations has highlighted the importance of quantitation of EtO and 2-CE residues in food.
