A new method was developed and validated using automated on-line solid-phase extraction (SPE) with tandem mass spectrometry (MS). Urine samples were enzyme-hydrolyzed and diluted before detection. The validated method was applied to positive authentic urine samples to evaluate concordance with high performance liquid chromatography (HPLC)–MS-MS results.

An important attribute of a novel ionization process for use in mass spectrometry (MS) is its simplicity and flexibility to be hyphenated to conventional liquid-based separation methods.

The main objective of this study was to evaluate the capabilities of gas chromatography (GC) with time-of-flight mass spectrometry (MS) for screening pesticides in fruits and vegetables using a purpose-built accurate-mass database.

Digital waveform technology is emerging as a powerful tool in mass spectrometry (MS). Digital quadrupoles rely on precise control of frequency rather than voltage, which allows these devices to access a greatly extended mass range

Bryan Vining from SGS Environmental Service in Wilmington, North Carolina, reveals some of the cutting-edge research his team has performed involving dioxin analysis, and proposes some future possibilities for the direction of this field.
