Raw Materials

QCL offers routine 10-15 business day turnaround-time for raw materials testing. Rush turn-around is available upon request and with prior approval. This applies to USP, EP, JP, BP, FCC, ACS, and client-supplied methods.  There is a 5-business day turnaround-time for all compendial purified water testing. QCL has a dedicated group of experienced chemists and our sample management system assures sample traceability.  All documentation is professionally detailed and completely GMP reviewed at test completion prior to issuance of the COA. Due to the stringent checks and balances between the laboratory and the Quality Assurance group, all final results are accurate and reliable.
