AN666: Routine analysis of polar pesticides in water at low ng/L levels by ion chromatography coupled to a triple quadrupole mass spectrometer

Instrument 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.

AN661: Fast routine analysis of polar pesticides in foods by suppressed ion chromatography and mass spectrometry

Instrument Type: ICMS

We present a reliable and cost-effective IC-MS/MS multi-residue method for high-throughput screening and quantitation of polar pesticide residues and their metabolites in food matrices below the current legislative requirements. In contrast to methods described in the literature, sample preparation is simplified and the use of ion chromatography speeds up the separation.

LC-MS/MS analysis of polar pesticides in honey with QuPPe extraction

Instrument 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.
