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.

New Oregon Cannabis Pesticide Standards—Injecting Confidence in Your Analysis

Restek is pleased to announce the launch of new pesticide residue standards to meet the specific cannabis analysis needs of Oregon—and states with similar pesticide residue regulations/programs. Dissolved in acetonitrile and formulated for stability, the 59 compounds are separated into 6 x 1 mL solutions with individual analyte concentrations of 600 μg/mL—resulting in a convenient 100 μg/mL solution when blended immediately before use. Designed with quality and convenience in mind, this set of standards eliminates the need for in-house standards preparation. Restek’s Oregon pesticide standards are certified reference materials (CRM) manufactured and QC-tested in ISO-accredited labs.

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.

Analyze Cosmetics and Personal Care Products for Ethylene Oxide and 1,4-Dioxane With New Restek® Standards

Restek PEG StandardsEthylene oxide and 1,4-dioxane are considered probable carcinogens by the U.S. EPA and International Agency for Research on Cancer respectively. These compounds are impurities in polyethylene glycol (PEG), but because of the potential danger they pose to humans, they must be removed before PEG can be used as a thickener / softener in cosmetics and personal care products.

Restek has formulated the only off-the-shelf suite of reference standards targeted toward the analysis of PEG-based products to make it easier for labs to verify the safety of shampoos, hand creams, and more. Produced with the specific concentrations needed in the industry, these newest Restek® certified reference materials (CRMs) are quantitatively tested to confirm their composition, and detailed support documentation is provided with each purchase. Because they are manufactured and QC-tested in Restek’s ISO-accredited labs, they also help satisfy ISO requirements.

With the release of these new ready-made reference standards, contract labs and manufacturers of PEG-based cosmetics and personal care products no longer need to order custom standards or make their own mixes.
