Release specification (every lot is tested to this)

Test	Method	Acceptance criterion
Appearance	Visual examination against the stated description	Clear, colorless solution
Water and benzyl-alcohol component identity	Qualified water-grade document review plus GC retention-time and FTIR comparison against a qualified benzyl-alcohol reference	Water grade conforms to the released specification and the preservative is identified as benzyl alcohol; component identity does not by itself establish concentration, sterility or finished-product status
Benzyl alcohol content	GC-FID with a qualified external reference and validated v/v calculation	0.9% ± 0.1% (v/v)
pH	Potentiometry (USP <791>)	5.0–7.0
Elemental impurities	ICP-MS (USP <233>), closed-vessel microwave digestion	Cd NMT 0.2; Pb 0.5; As 1.0; Hg 0.3; Co 0.5; V 1.0; Ni 2.0; Li 5.0; Sb 1.0; Cu 5.0 ppm; sum of Cd, Pb, As, Hg, Co, V and Ni <4.0 ppm
Antimicrobial effectiveness	USP <51>, Category 1 challenge with five specified organisms through 28 days	Meets USP <51> Category 1 criteria for the tested released formulation; this result does not sterilize a contaminated vial or replace aseptic controls
Fill volume	Gravimetric determination with validated density correction	5.00 mL/vial ±3.0%
Particulate matter	Light obscuration (USP <788> Method 1); visible particles per USP <790>	NMT 6000 particles ≥10 µm and NMT 600 particles ≥25 µm per container; essentially free from visible particulates
Bacterial endotoxins	Kinetic chromogenic LAL (USP <85>)	NMT 0.25 EU/mL
Sterility	USP <71>, membrane filtration with demonstrated method suitability	Sterile — no growth
