Abstract

Polyethylene film has been used recently for preparing cells for infrared analysis <i>(1, 2)</i>. We have successfully adapted this technique for samples as small as three μl for liquids and three mg for solids. Also, we have found that compensation of spectral bands for the polyethylene may be achieved by use of an appropriately made blank, thus increasing the spectral usefulness of the technique.
