Certified Reference Material (CRM) is the main quality standard within a laboratory's analytical routine. With it, it is possible to verify 

Cayman's Phytocannabinoid Mixture 11 (CRM) is a certified reference material mixture for the quantitation of 11 prevalent phytocannabinoids against a calibration curve. The mixture contains Δ 9 -THC, Δ 8 -THC, THCA-A, CBD, CBDA, CBN, CBC, CBG, CBGA, CBDV, and THCV. This mixture is intended for HPLC-UV or LC- or GC-MS instrumentation.

Vanguard Solutions, Inc. and its subsidiary, www.Coalstandards.com bring over 30 years experience in the manufacturing and certification of coal and coke standards. We have a large catalog of in stock standards and the lowest prices. Samples consist of material with NIST traceability and multiple laboratory determinations. Certified reference

Certified Reference Materials (CRMs) Genetically modified crops have been commercially available since the mid-nineties. Due to opposing views on genetically modified crops, laws

The material is generally a certified reference material, analyzed by methods meeting ISO 17025 and blended by ISO 17034 guidelines and shipped blind to all participating laboratories. After the laboratories analyze the samples, the results are submitted to DCG for consolidation and analysis. DCG will issue a final report to the customer and

The IAEA Environment Laboratories produce certified reference materials for the measurement of radionuclides, trace elements and organic contaminants.

Matrix-based certified reference materials are used by clinical assay manufacturers to access the trueness of their calibrators and quality control materials.

Organic Analytical Standards:

Micromeritics Certified Reference Materials (CRM) kits are the newest validation tools from the world leader in particle characterization technology. These kits offer a convenient method for

The spectral certified reference materials have a form of discs 40 mm in diameter and 20 mm to 30 mm height as well as in form of rods 6 or 10 mm in diameter and 100 mm long. The chemical reference materials have a form of a powder of determined grainsize (ores, concentrates), of chips (metals) and rods of various dimensions.
