California and Oregon residual pesticide analysis using APCI with LC-MS/MS
9 Mar 2020With the increase in medicinal and recreational cannabis legislation throughout the United States, there is an emerging demand for pesticide testing on cannabis products. In this application note, Shimadzu demonstrates the use of atmospheric pressure chemical ionization (ACPI) and liquid chromatography-mass spectrometry (LCMS), while also exploring the utility of LCMS for the analysis of complete California and Oregon pesticide lists for cannabis.

LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis.
