Abstract

Liquid cells of constant path length with high density polyethylene windows for the it region are generally difficult to obtain. Most commercially available 1 polyethylene cells are sufficient only for survey spectra and cannot be used for careful measurements during long or repeated scans since repeatability and adequate absorbance measurements 2 are difficult to obtain. Moreover, the measurement of air sensitive solutions is often unsuccessful because air leaks develop and because determining the actual cell thickness is not easy.
