Hi Jim,

Thank you for the response.

Somewhat related, has anyone come across any literature showing when peroxide concentration starts to affect organism growth? I know this is probably too general but I wouldn't imagine something like 5 ppm showing much inhibition.

Hi Nick,

I have used EMD Millipore MQuant H2O2 test strips over the years for a semi-quantitative (0.5-25 ppm) assay of WFI in a variety of containers.
There are a variety of quantitative assays available that can accurately detect concentrations in the ppb range. The VHP Validation Manual from STERIS describes a Xylenol Orange Spectrophotometric assay that is accurate down to the 100 ppb range.

Subject: [PMFLIST] VHP concentration testing in liquid

Hello,

I was curious what others are using to test VHP concentration in liquids when performing VHP penetration testing. We are currently using test strips from Water Works, though I am not sure how accurate these are. I could also foresee issues with dark colored liquids as well since you are using a color change scale similar to pH test strips.

Thank you,
