Chromate
US laboratory that also runs an unannounced product-testing project. Each report can be checked at chromate.org/verify with the report number and the access code printed in the certificate footer, which returns the laboratory's own rendering. Its reports identify each compound by RP-HPLC with UV detection rather than mass spectrometry, and recent reports add sterility and endotoxin results. The laboratory gives its location only as Hudson, New Hampshire, and its reports are signed by Lucas Weber, Principal Chemist; New Hampshire's register lists Chromate Analytical Group LLC of Nashua for analytical testing services (read 22 October 2026). No accreditation is documented. Methods: HPLC.

The others are Chroma Technology Corp. and a New York company in administrative suspension.Evidence for L1 (opens in new tab)quickstart.sos.nh.govchecked |
