Calibration Standards

Zinc Atomic Absorption Standard is a chemical element similar to magnesium and an abundant element of the Earth’s crust. The largest amounts are found in the US, Australia, and Asia. This product is used to calibrate the atomic absorption spectrometer for the determination of the concentration of a metal in a sample to be analyzed. Spectrum AA standards are traceable, precise and pure. Trust your ingredients!

Cannabigerol (CBG), 1,000 ug/mL (1,000 ppm), in Methanol. While the legalization of cannabis, for both medicinal and recreational purposes, has been gaining speed, legislation and regulation has not necessarily kept pace. Even so, 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 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 offerings. Designed for methods: State specific pesticide regulations: OAR 333-008-11 HB 3460 AOAC 2007.01 EN 15662 SPEX CertiPrep is registered by the United States Department of Justice Drug Enforcement Administration as a manufacturer of Controlled Substances/Regulated Chemicals under Registration #RS0489737.
