Caligreen Laboratory is dedicated to providing quick,
reliable testing through the latest technology.
We use state-of-the-art equipment, employing a full suite of analytical instrumentation suitable for the
wide range of testing necessary to meet all state regulatory requirements. This includes:
LC MS/MS (Liquid Chromatography Tandem Mass Spectrometry)
Pesticides that may be used during the cannabis growing process to control harmful insects, weeds or other organisms can be harmful to consumers. In addition, the relatively high moisture content of cannabis makes it susceptible to mold growth during storage, producing mycotoxins. LC MS/MS analysis allows detection at the ultra-low levels necessary to ensure regulatory compliance.
ICP-MS (Inductively-Coupled Plasma Mass Spectrometry)
Toxic heavy metals such as cadmium, lead, mercury, and arsenic are found in soils and fertilizers, and can be taken up by cannabis plants as they grow. ICP-MS testing can detect these metals at extremely low levels.
HPLC (High Performance Liquid Chromatography)
Producing reliable products and meeting labeling standards requires detailed knowledge of the cannabinoid content. The HPLC enables rapid detection of the levels of 11 different types of cannabinoids.
GC MS/MS (Gas Chromatography Tandem Mass Spectrometry)
Regulatory compliance testing encompasses a wide range of pesticide residues to ensure the safety of all cannabis products. Some of these pesticides are not suited for LC MS/MS analysis to obtain reliable results at ultra-low levels. In order to maintain the highest level of quality, GC MS/MS is used to detect these select pesticides.
HS-GCMS (Headspace Gas Chromatography Mass Spectrometry)
Terpenes are the compounds that give cannabis its characteristic flavor and scent, and the unique combination of cannabinoids and terpenes found in a particular strain can give it different characteristics and effects. In addition, many cannabinoid products are made by extracting cannabinoids and terpenes from cannabis using solvents. Residual solvents are the chemicals left over from this process, which are not safe for consumption. HS-GCMS analysis can identify thousands of different terpenes, as well as low levels of residual solvents.
