What have you been smoking? Elemental Analysis in Cannabis and Cannabis Products with ICP-MS

To match the demand of the increase of food testing in various laboratories, a reliable automatic calibration and dilution sample introduction system is employed in the elemental analysis of food products by ICP-MS. The new sample introduction system combines calibration preparation, pre-dilution and reactive re-dilution of samples into one simple step during method setup. This simplifies the operation and analysis, which minimizes contamination and human error, ensures accuracy and traceability, in addition to enhancing lab personnel training. In addition, to ensure accuracy of the results, half mass correction is employed to combat the common doubly charge interference by rare earth metals. This presentation will discuss the mechanics of this sample introduction system, as well as results obtained by ICP-MS.
