Confidence Analytics, Washington state licensed and accredited cannabis testing laboratory
Tania A. Sasaki, PhD – Chief Science Officer
There are several methods for cannabis testing and many sample matrices. The plant itself is complex and variable and then there are different products such as concentrates, oils, lotions edibles, etc. This diversity can make sample preparation complex and/or difficult, possibly requiring methods for extraction and/or cleanup to be adapted to each type of product. Cannabis products are quite different from each other and from the original plant, so extraction efficiencies, potential matrix effects, and interferences can be unpredictable. Laboratories have limited time and budgets, so cannabis sample preparation products need to be easy to use, affordable, and effective.
Prior to DPX, Confidence Analytics used several different filtration techniques depending on the cannabis product/matrix and downstream analysis they needed to perform. They were using spin filter vials, filter plates and syringe filters.
Cannabis matrices are homogenized and analytes(s) of interest are extracted with the appropriate solvent. DPX Dual Phase Filtration tips are used to filter aliquots of the solvent extract to remove particulates prior to downstream analysis. Confidence Analytics replaced all other filtration products with DPX Filtration tips and had a cost savings of up to 44%. “The tips were much easier to use compared to other products and had fewer steps. As a result, we improved the efficiency of our workflow and reduced the potential for error or contamination. We also decreased the number of products we had to stock, which simplified our inventory.” – Tania A. Sasaki
