Target Mycotoxins in Cannabis with Restek’s New Ochratoxin A & Aflatoxins Standards

Mycotoxins are toxic secondary metabolite compounds produced by mold or fungi. Due to the toxicity of certain mycotoxins that can be found on cannabis plants, there is a growing need to detect their presence in both raw plant materials and finished cannabis products.

Restek now offers two new mycotoxin certified reference materials (CRMs): Ochratoxin A (cat.# 34122) and Aflatoxins (B1, B2, G1, G2) (cat.# 34121).

These new reference standards enable labs to expand their cannabis analyses with a Restek solution when coupled with our high-throughput Raptor ARC-18 (cat.# 9314A12) LC column.

Advance Your Analysis of Cannabis With Our New Cannabidivarinic Acid (CBDVA) Standard

Cannabidivarinic Acid (CBDVA) is a non-psychoactive cannabinoid reported to have anti-inflammatory properties. While its medicinal benefits are still being researched, quantifying this compound in cannabis samples is crucial for obtaining a true measurement of potency and chemovar identification. Restek now offers a new CBDVA certified reference material (CRM) to help labs advance their analysis of cannabis.

Restek’s new CBDVA standard is ideal for creating multipoint (5-point minimum suggested) calibration curves for LC analysis. With verified composition and stability, this prepared stock product eliminates the need for in-house standards preparation for greater convenience and lower labor requirements. As it’s excluded from U.S. DEA Controlled Substances Act (CSA) regulatory controls, no customer permits or licensing required to purchase within the U.S., and because it’s manufactured and QC tested in Restek’s ISO-accredited labs, this new CBDVA standard qualifies as a certified reference material (CRM) that satisfies your ISO requirements.

Attain a More-Comprehensive Characterization of Cannabis Samples with Restek’s New Cannabicyclol (CBL) Reference Standard

Cannabicyclol (CBL) is formed through the photodegradation of cannabichromene (CBC). Levels are typically quite low, and the medicinal benefits of CBL are still being researched, but quantifying this compound in cannabis samples is crucial for obtaining a more-complete cannabinoids profile. Restek has just released a new CBL certified reference material (CRM) to further aid labs in the comprehensive characterization of cannabis: www.restek.com/catalog/view/54615

Restek’s new CBL standard is ideal for creating multipoint (5-point minimum suggested) calibration curves for LC analysis. With verified composition and stability, this prepared stock product eliminates the need for in-house standards preparation for greater convenience and lower labor requirements. As a U.S. DEA-exempted formulation, no additional customer permits or licensing are required to purchase within the U.S., and because it’s manufactured and QC tested in Restek’s ISO-accredited labs, this new CBL standard qualifies as a certified reference material (CRM) that satisfies your ISO requirements.

Cannabidivarin (CBDV) Added to Restek’s Selection of Cannabis Reference Standards

Cannabis strains with high levels of cannabidiol (CBD) typically have higher levels of cannabidivarin (CBDV) as well, but accurate quantitation of both compounds for potency and strain ID is a must, especially as interest in using CBDV as an anticonvulsant and anti-nausea treatment continues to rise. Restek now offers a stand-alone CBDV reference standard—in addition to CBD and a host of other compounds—to help labs with the comprehensive analysis of cannabis products.

Restek’s CBDV standard is ideal for creating multipoint (5-point minimum suggested) calibration curves for LC-MS/MS. With verified composition and stability, this prepared stock product eliminates the need for in-house standards preparation for greater convenience and lower labor requirements. As a U.S. DEA-exempted formulation, no additional customer permits or licensing are required to purchase within the U.S., and because it’s manufactured and QC tested in Restek’s ISO-accredited labs, this new CBDV standard qualifies as a certified reference material (CRM) that satisfies your ISO requirements.

The Industry’s Favorite Reference Standards Packaging Just Got Better—Restek Begins Transition to GHS Labeling

ampule_box_2_ph_arm_2Effective immediately, Restek will be transitioning away from NFPA* to universally recognized GHS labeling for our reference standards.

GHS, or the Globally Harmonized System of Classification and Labeling of Chemicals, is a set of provisions for hazard classification and communication developed by the United Nations. Its goal is to universally label products that can be opened, thus exposing users to the materials contained within, in a way that clearly identifies any potential safety concerns regardless of the user’s language, country, or background. Efforts to implement GHS labeling have begun around the globe; for the United States in particular, OSHA will require that products shipped after June 1, 2015, carry universally recognized GHS labeling to ensure safety regulation compliance.

In order to improve the safety communication included with Restek® reference standards and ensure that we can provide uninterrupted service to our customers, Restek has already started phasing out our use of NFPA labeling. During the transition, Restek customers may receive a mix of GHS- and NFPA-labeled reference standards, but our entire reference standard inventory will be converted to GHS labeling well in advance of the June 1, 2015 deadline. In the near future, we will also begin transitioning our wool, bulk packings for GC and LC columns, and other products to GHS labeling.

Restek has extensively studied the GHS system and OSHA’s requirements for using it to help our customers not only convert their own inventories properly, but also do so ahead of schedule. This change will not affect product composition or quality in any way; it is merely a change in labeling practices. Our goal is to make the transition to GHS labeling compliance as seamless as possible. Our new convenient GHS labels are bar coded with both catalog and lot number, and they are also removable for easy transfer of standard information into lab notebooks.

The conversion to GHS may seem like a challenge to many labs, but relying on Restek’s safety compliance experts and using our reference standards is one way to make the transition easier.

If you have any questions about GHS labeling for Restek® reference standards, contact Jason Fisher by phone at 1‐814‐353‐1300, ext. 2409, or by email.

* Hazard labeling that follows NFPA (National Fire Protection Association) 704 standards is best known for the use of 4 colored diamonds, each most often containing a numeric code.

Restek Offers the Latest USP <467> Class 2 Residual Solvents for Pharma Analysis

Restek is a long-time partner of pharmaceutical QC labs performing residual solvent analysis, and our support continues with the release of an updated Class 2 Mix A reference standard.

About USP <467> Class 2 Residual Solvents:

The United States Pharmacopeia (USP) General Chapter <467> Residual Solvents is a widely used compendial method intended for identifying and quantifying residual solvents in drug substances, drug products, and excipients. This method identifies acceptable amounts of solvent residues that can be present, and the solvents are summarized by class according to their toxicity. Class 2 compounds are nongenotoxic animal carcinogens, and concentrations of these compounds should be limited. Chromatographic analysis is needed for both the Class 1 and Class 2 residual solvents. This new standard reflects the changes made in USP <467> effective August 2013 and replaces Restek® cat.# 36271.
