WebFor WFI, the USP guidelines require a conductivity limit of 0.6–4.7 µS/cm, a TOC limit of 500 ppb (µg/L), an endotoxin limit of 0.25 endotoxin units/mL and a bacteria-count limit of 10 cfu/100 mL. The main difference between PW and WFI is the amount of bacterial contamination allowed, measured by colony count and by endotoxin level.
