Pesticide Testing

Pesticide analysis is accomplished through the use of a Liquid Chromatography Triple Quadrupole Mass Spectrometry (LC-MS/MS) instrument here at MRX Labs. The analytical sensitivity of this instrument is very useful to ensure we can detect and accurately quantify all state required pesticide analytes at their action limit and below.

The analytical process of the instrument has a similar sampling process as a High Pressure Liquid Chromatography instrument that involves a mobile phase composed of multiple solvents, adsorbent column and pump system. The significant difference is the use of an EI spray to disperse the sample through the first MS. The first MS allows the precursor ions of interest into the collision cell, where they are collided with a neutral gas, argon gas, to create product ions that are fragments of the precursor ions. In both the first and third quadrupole, the system “scans” for both precursor and product ions that are quantified. Each analyte has unique precursors and product ions, giving us the ability to identify specific analytes easily. The use of two mass analyzers allows us to identify and quantify trace amounts of an analyte by drastically reducing the amount of non-target analytes in the measurement portion of the system.

We are accredited through the state of Oregon and ORELAP to test products for the detection of pesticides in accordance will all testing regulations. We offer research and development tests to processors working on new products; while not sufficient for market sales it allows us to estimate concentrations to a finer degree and does not mandate fail reporting to the state. Please inquire about this process directly with the lab.
