Testing Facility


Liquid chromatography- tandem mass spectrometry (LC-MS/MS) has become the method of choice for many analytical applications due to its high selectivity and sensitivity as well as its suitability for a wide range of compounds in various sample matrices. With the legalization of cannabis for medical and recreational applications in Canada and in many States in the US, LC-MS/MS method has been applied for the analyses of pesticides and other toxic chemicals such as mycotoxins to control the quality of the cannabis products and to evaluate the risk of human exposure.
In LC-MS/MS, target analytes in a sample were first separated from each other and from potential interfering components by liquid chromatography (LC) and then identified and quantified by tandem mass spectrometry (MS/MS) as compared with reference standards.

Brookfield Viscometer with Helipath small sample adapter :

A viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluid. For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used.
There are several models of viscometer available from Brookfield but the majority operate in the same manner: the viscometer motor rotates the spindle at a defined speed (measured in rpm) or shear rate and the viscometer measures the resistance to rotation and reports a viscosity value.

Dissolution Tester :

In the pharmaceutical industry, drug dissolution testing is routinely used to provide critical in vitro drug release information for both quality control purposes, i.e., to assess batch-to-batch consistency of solid oral dosage forms such as tablets, and drug development, i.e., to predict in vivo drug release profiles.
The main objective of developing and evaluating an IVIVC is to establish the dissolution test as a surrogate for human studies, as stated by the Food and Drug Administration (FDA). Analytical data from drug dissolution testing are sufficient in many cases to establish safety and efficacy of a drug product without in vivo tests. Thus, the dissolution testing which is conducted in dissolution apparatus must be able to provide accurate and reproducible results.
