Extraction of Malachite Green, Crystal Violet and their Leuco Metabolites from Salmon Using QuEChERS and EVOLUTE CX for LC-MS-MS Analysis
14 Jun 2012This application note describes the extraction of malachite green, leuco malachite green, crystal violet (gentian violet), leuco crystal violet (leuco gentian violet) and brilliant green from oily fish tissue using enhanced dispersive SPE followed by EVOLUTE CX clean up. The work focuses on ease of use when compared to other methods, and describes a QuEChERS based approach incorporating the use of aluminium oxide in enhanced dispersive SPE to reduce the levels of fat in the final extract.

Solid-Phase ExtractionSolid-phase extraction (SPE) is used for clean-up, extraction and concentration of semi-volatile or non-volatile analytes from complex mixtures including blood, urine and food samples. Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats.
