Abstract
It is demonstrated that chlorophyll can in principle be used as a modi fier of acetonitrile-water (1 : 1) and hexane-n-butanol (96 : 4) mobil e phases for the indirect photometric detection of phenol; o-, m-, and p-nitrophenols; and alcohols in the visible spectral region (404 and 660 nm) in reversed-phase and normal-phase high-performance liquid chr omatography. It is confirmed that indirect detection in chromatographi c systems is possible when an injection of a sample disturbs the equil ibrium distribution of at least one component of the mobile phase to t he point where it can be detected.
