Analyst Comments
Clear, colorless aqueous solution, blue-cap multi-dose vial, received sealed. Vial is printed lot DRC-BW10-0928; reported under lot DRC-BW10-1027 as confirmed by the client. The sample was injected undiluted and diluted about 20-fold, and benzyl alcohol was not found (detection limit about 0.05% w/v). The chromatogram shows the diluted injection; the dashed trace is a benzyl alcohol reference run on the same method, marking where benzyl alcohol elutes. The only significant peak is an unidentified UV-absorbing component.
