Cleanliness Verification

Following our philosophy that the first step in verification is the last step in cleaning, we begin the verification process with a syringe flush of purified and filtered AK-225. We continue with subsequent flushes capturing the effluent for particle counts and non-volatile residue (NVR) analysis.  The Janzen Wahl Group’s proprietary NVR analysis method:

  • Is suitable for small quantities and sizes of hardware

  • Requires less than 20 minutes to perform

  • Uses less than 1 mL of solvent

  • Allows for hundreds of tests from a single batch of verification solvent

  • Increases test fidelity by dramatically reducing sources of error.
