Application Note: Signaling Substances Used in Plant Defense: HPLC-MS/MS Analysis of Jasmonates

Plants must be capable of responding to climatic fluctuations, diurnal rhythms, available supplies of water and nutrients, and insect attacks and infestations. To ensure such responses, plants need a network of regulating substances called phytohormones. In this article you can read a discussion of a highly sensitive analytical method for quantitative determination of phytohormones.

Keep in mind: Water is used heavily for rinsing and dilution of samples to be tested. Furthermore, it is used for the preparation of certified reference materials within the calibration and testing of the instrumentation (GS-MS, HPLC) to evaluate the samples for contamination in the Cannabis testing process.
