An Alternate Batch CRM is available to customers who are required to purchase a second/alternate batch CRM when preparing independent calibration and control stocks while doing quantitative analysis. For example, if you wish to purchase two independent batches of THCA-A (CRM), you’d add items “THCA-A (CRM)” and “THCA-A (Alt. Batch CRM)” using their independent item numbers ISO60175 and 41194. 

Alternate Batch CRMs have been prepared, tested, and certified independently under the same processes and specifications as the primary CRM equivalent. Ordering an Alternate Batch CRM as a separate Item No. allows for simplicity and confidence in the ordering process.

How do I request an independent or alternate batch CRM?

If a CRM has an Alternate Batch available it will be mentioned in the product features, description, and “Alternative(s)” Product Relationship dropdown on the product page. Customers may add this to their order like any other product. If an Alternate Batch CRM version is not readily available, customers may continue to request an Alternate Batch on their purchase order or by contacting sales@caymanchem.com for a quote.
