The measurement of phenol coefficients by flow microcalorimetry

Authors:

Abstract
Microcalorimetric bioassay procedures have been applied to the determination of phenol coefficients and dilution coefficients. The derived values are compared with those from a standard AOAC test procedure. The microcalorimetric results indicate close agreement with AOAC values, good reproducibility (±2%), rapidity (30 min per test), potential for automation and the determination of in-use dilutions of disinfectants.
