USP purified water and WFI testing, run by a lab that gets back to you.

ACTA tests Purified Water, Water for Injection, Process Water, and Packaged Water to the USP compendial chapters for total organic carbon, conductivity, bacterial endotoxin, and microbial enumeration. Send us the system and the tests, and a scientist scopes the work.

What we test

USP water testing, chapter by chapter

Purified Water and Water for Injection are defined by the tests that pass. ACTA runs the full compendial panel and reports each result against the USP limit, so your quality group has release-ready data.

<643>

Total Organic Carbon

Detects trace organic compounds in the water. The bulk water limit is 0.50 mg/L (500 ppb). Run in the lab or by online limit response.

<645>

Water Conductivity

Measures dissolved ions such as sodium and chloride by how well the water conducts electricity, evaluated in the three stage USP procedure.

<85>

Bacterial Endotoxins (LAL)

Required for Water for Injection, with a limit of 0.25 EU/mL. Purified Water has no compendial endotoxin requirement.

<61><62>

Microbial Enumeration

Total aerobic microbial count by USP <61>, with tests for specified microorganisms by <62>, counted against the action levels defined in <1231>.

<788>

Particulate Matter in Injections

Subvisible particulate testing by both Method 1 (light obscuration) and Method 2 (microscopic), for injectable and sterile waters.

Reported against the USP limit

ACTA measures TOC and conductivity and evaluates each result against the USP acceptance criteria, then reports the numbers your quality group needs to release a batch or investigate a water system.

Purified Water vs Water for Injection

AttributePurified WaterWater for Injection

Water for Injection is the stricter grade. It adds bacterial endotoxin control and a far tighter microbial action level for injectable use. Sterility testing (USP <71>) is out of scope.

<1231> Water for Pharmaceutical Purposes is the informational chapter that governs the whole water program. It defines the water types and the microbial action levels above. It is the standard your system follows, not a single test.
Why ACTA

The small water job the big labs will not take

Large labs pass on small water testing projects, or take a month just to open an account. ACTA runs them. We get back to you, we follow up, and the work grows from there. You get an FDA registered, DEA licensed, cGMP lab that treats a small account like an account.
