Article: 00092602

Water content analyzer / methane / for liquids / UV

Application Summary

Analyte: Trace impurities in a cleaning solvent (e.g. water, methanol)
Process Stream: Cleaning solvent

Introduction

Clean-in-Place (CIP) is a method commonly used to clean the interior surfaces of production equipment. In the process, cleaning solvents such as methanol or water are circulated to sanitize walls, pipes, tanks, etc. To satisfy regulations, the wash must effectively remove all active ingredients from previous production run.

CIP is a stage of significant downtime; production will be stalled until the process is complete. Plants that still use a set duration or depend solely on swab tests are suffering unnecessary downtime and costs. Allowing CIP to run longer than it needs to is an oversight that wastes production time and CIP solvents.

Using an OMA system, the wash cycle is validated in real time. An active ingredient (the substance which is being eradicated) will typically show distinct absorbance curves in the UV-Vis or SW-NIR ranges; the OMA monitors this absorbance to measure the current concentration of active ingredient X in the effluent celaning solvent (rinse water). When the threshold concentration is reached in the continuously drawn rinse water sample, the OMA immediately notifies the user or external system. This functionality reduces unneeded CIP downtime and removes dependency on labor-intensive swab tests.
