On-Line Sorption–Chromatographic Determination of Phenols with Amperometric Detection

Conditions of the preconcentration of phenol on a microcolumn filled with MN-200 hypercrosslinked polystyrene were determined using the linear sorption dynamics model. Conditions of the on-line determination of phenol and its chloro derivatives by reversed-phase high-performance liquid chromatography with amperometric detection were optimized. The detection limit of phenol and chlorophenols for preconcentration from 30 mL of a sample was 3 and 15 ng/L, respectively. The proposed procedure was used for the determination of phenols in tap and river water.

This paper reports an attempt to solve the problem of the determination of phenol by extraction and GC

Liquid Chromatographic Determination of Phenol and Cresols in Total Particulate Matter of Cigarette Smoke

The phenol and cresol contents of the total particulate matter of tobacco smoke can be conveniently determined. A simple extraction procedure using 1N base is followed by partial neutralization with glacial acetic acid and elution of hydroxybenzenes from an end-capped reverse phase liquid chromatographic column. The procedure is rapid (20 min/sample after the initial extraction), precise (+/- 10% relative standard deviation), accurate, and convenient. Normally, 12 or fewer cigarettes are needed for a single measurement.

High Pressure Liquid Chromatographic Determination of Phenol in Honey

A method is described for determining phenol in honey by using high pressure liquid chromatography (HPLC). An internal standard, 2-phenylethanol, was added to honey which was steam-distilled and chromatographed on a 25 cm x 3.2 mm id Spherisorb 5 micro m silicic acid column using water as the mobile phase. Absorbance was monitored at 195 nm. Using a mixed standard of known concentration and peak height measurements, the amount of phenol in the honey could be quantitated. Recovery of added phenol was checked at levels from 0.1 to 33 ppm.

A gas-liquid chromatographic determination of phenols on octa-2?4-xylenyl pentaerythritol tetrakis phosphate

The paper describes the use of octa-2∶4-xylenyl pentaerythritol tetrakis phosphate as a stationary phase suitable for the determination of trace quantities of phenols by gas-liquid chromatographic technique. The phase was designed with two major factors in mind: a good separation of the isomeric xylenols and cresols and high thermal stability for the stationary phase.
