Cross-calibration of dual-stage detector is a very important procedure that enables extension of a dynamic range of an inductively coupled plasma mass spectrometer. A calibration procedure based on the measurements of the intensities of argon plasma ions and matrix ions protects the spectrometer against contaminations; however, it can lead to the misinterpretation of the measured data, especially...
The aim of this study was to develop a simple and effective multi-residue screening method for determination of pesticides residues in cereal products. Ion trap-based mass spectrometer was used as a detector in a high-resolution chromatographic system. The method involved sample extraction with acetonitrile and cleanup of the extract on disposable SPE cartridges. Method performance was evaluated using...
