Analyzing Edibles? Try These QuEChERS Techniques for High Sugar and Starch Samples
The polysaccharides present in sugary and starchy samples can cause troublesome analytical interferences and even accumulate in LC and GC systems to the point that the instrument must be taken offline for maintenance. In this blog, we discuss how to avoid these problems by correctly applying QuEChERS.
Modifying QuEChERS for Complex Matrices: High Fat Samples
Samples containing high amounts of lipids or solid fats are perhaps the most challenging matrices to analyze. Here we examine a range of approaches that can be effective, including dSPE (with PSA, MgSO4, and C18-EC sorbents), cooling/freezing QuEChERS extracts, cSPE, and nonpolar solvent partitioning.
Getting Your LC Up and Running Again After Extended Downtime
Many cannabis labs that slowed down due to COVID-19 are ramping up again and bringing instruments back online. But, just like a car that isn’t used for a long time needs to have its fluids, filters, and tires checked and maintained, your LC has similar needs. Here’s how to start back up properly and prevent problems down the line.
CA Pesticides and Mycotoxins: What’s in Your Edibles?
In this video poster, we present sample prep and instrumental strategies for effective quantitation of California’s list of pesticides and mycotoxins in cannabis brownies. Using both LC-MS/MS and GC-MS/MS, good results were obtained for all target compounds in terms of linearity, accuracy, and precision.
