Brilliance Yang Cleaning Verification Swab Kit Test Procedure

Confirm that the equipment is clean and the operator is dressed in work clothes suitable for testing (clean gloves, mask, gown, hairnet, clean environment).
Take a “clean” Low TOC swab in the Certified Low TOC vial.
Fill the vial with 40 ml of ultra-pure Low TOC water and seal.
Vortex the vial for 15 seconds.
Fill another certified low TOC vial with 40 mL of ultrapure, low TOC water and seal. This will be used as a “blank control”.
Run a TOC test through the “control blank” dosing vial and water level of the instrument. The unit of measurement should be μg/L.
Pass the vial with the swab inside through the TOC test device. Measurements should be in μg/L.
Subtract the “control blank” from the swab vial to get the final measurement. All measurements should be in μg/L. Our goal is less than 50 μg/L.
