Standards

Meeting regulations in any industry, standards are essential for periodically checking the accuracy of equipment pieces. By comparing against the known values, output readings detect errors present and inform personnel adjustments are required. Once the settings of the manual or automatic instruments have returned to zero, the reestablished conditions will yield optimal working performance. Calibrating with concentrated standards eliminates the possibility that environmental changes will induce instrumental miscalculation when accuracy matters most.

Organochlorine Pesticides Mix A, SPEX CertiPrep

Supplier: SPEX CERTIPREP LLC

Analytical Standards for Medicinal and Recreational Cannabis Testing
Pesticide Residues

While the legalization of cannabis for both medicinal and recreational purposes has been gaining speed, legislation and regulation has not necessarily kept pace. Out of a drive for self-regulation and significant consumer safety concerns, many producers and manufacturers are turning to testing labs in order to ensure that their products are of high quality and free of chemical contaminants.

SPEX CertiPrep offers ISO/IEC 17025 and ISO 17034 Certified Reference Materials (CRMs) for all of the common contaminants such as pesticide residues, residual solvents and heavy metals, as well as qualitative analysis CRMs, such as terpenes. As the
industry demands change and regulations are put into place, we continually update our product offering.

Designed for Methods: State specific pesticide regulations:
• OAR 333-008-11
• HB 3460
• AOAC 2007-01
• EN 15662
