A UV laser photoacoustic(PA) method with high sensitivity and accuracy using a novel open-ended cell was developed. This PA cell was constructed by processing the end of a light guide as the sample chamber and by attaching an acoustic pipe bent at a right angle. The newly developed PA method is applicable to the study of percutaneous absorption.
