Special Issues
The sensitive, selective, and real-time analysis characteristic of the SIFT-MS technique provides simple, robust, and continuous analysis of extremely diverse odor compounds at trace levels in air. This application note illustrates instantaneous, broad spectrum odor analysis with monitoring data from a chicken meat production facility.

A rapid, accurate, and reproducible method was developed for high-throughput testing of nicotine, cotinine, trans-3’-hydroxycotinine, nornicotine, norcotinine, and anabasine in urine. Data show that a fast and highly efficient analysis of these basic compounds can be achieved with the Raptor Biphenyl column using standard reversed-phase LC–MS mobile phases that are compatible with a variety of LC–MS instrumentation.

There are nearly one thousand pesticides used in modern agricultural practice, and the residues of pesticides in the food from plant origins have been an increasing concern for consumers worldwide. Monitoring programs based analytical methodologies are established to ensure that the pesticide levels in plant foods are in compliance with national and international laws. However, the diversity of pesticides and complexity of food sample matrix present ongoing challenges for analytical chemists to meet the increasingly stringent requirements for sensitivity, precision, and throughput.

Increasing temperature can cause chemical changes, alter reaction rates, concentrate an aqueous sample, or evaporate a solvent. These transformations can be readily monitored by diamond ATR spectroscopy. This note explores the use of a diamond ATR to examine heat-induced changes in the clay.
