As laws and regulations change, cannabinoids and related compounds of interest are showing up in a wide variety of consumer products. LECO's gas chromatography mass spectrometers empower labs to simplify their workloads by screening for pesticides, terpenes, and cannabinoids in a non-targeted, more efficient way. Thermogravimetric moisture analyzers allow researchers to develop accurate methodology for determining moisture content in the organic material.

We know you have cannabis questions. We're here to help you see what you've been missing.

Editors' Series: Exploring Chemical Constituents in Cannabis Using Nontargeted GC and GCxGC with TOFMS

Cannabis is difficult to analyze due to its chemical diversity and the wide concentration ranges of its constituents. This diversity is important in determining its utility, potency and medicinal effectiveness. Julie Kowalski [JA Kowalski Science Support] discusses using GCxGC TOF-MS to determine constituents (such as cannabinoids, terpnes, flavonoids, and contaminants) in cannabis samples. On-demand webinar.
