Yes! Reference standards manufactured within our scopes of our accreditation (i.e., CRMs) are traceable as follows:
- All analytical balances are verified at seven mass levels daily using NIST traceable weights and are also calibrated yearly by an ISO/IEC 17025–accredited provider to guarantee accurate measurement.
- Volume is assured by using Class A volumetric flasks and/or Class A pipettes.
- Raw materials are characterized to confirm identity and purity using two or more of the following techniques: GC-FID, HPLC, GC-ECD, GC-MS, LC-MS, refractive index, and melting point.
- Only the purest materials available are used; any material with purity less than 99% is weight corrected.
