AN666: Routine analysis of polar pesticides in water at low ng/L levels by ion chromatography coupled to a triple quadrupole mass spectrometerInstrument Type: ICMS
We present an IC-MS/MS based method for high-throughput screening and quantitation of polar pesticide residues and their metabolites in water matrices below the current legislative requirements. Direct injection eliminates long and laborious sample preparation and makes the method more sensitive and faster than traditionally used LC-MS/MS methods, which utilize FMOC derivatization. This method can increase cost savings, provide more reliable results, and increase sample throughput.
LC-MS/MS analysis of polar pesticides in honey with QuPPe extractionInstrument Type: LCMSMS
We present a sensitive, robust, fast method to determine and quantify residues of polar pesticides in food samples in complex matrices at required regulatory levels. The Thermo Scientific UltiMate 3400 RSLC system is used in combination with a Thermo Scientific TSQ Quantiva triple quadrupole mass spectrometer to analyze QuPPe method extracts. The robustness of the system allows uninterrupted analysis of up to 500 honey samples and easy cleaning of the ion introduction system.
High-Throughput, Cost-Efficient LC-MS/MS Forensic Method for Measuring Buprenorphine and Norbuprenorphine in UrineInstrument Type: LCMSMS
Due to its increased abuse, forensic and testing labs test routinely for the presence of buprenorphine and its metabolite norbuprenorphine. To reduce their case backlog, these labs need cost-efficient analytical tests on hundreds of samples. We developed a high-throughput screening and quantitation LC-MS/MS method in which urine samples are quickly prepared and analyzed by a short chromatographic method implemented on a four-channel LC-MS system for improved productivity. For forensic use only.
