Rapid static headspace sampler for automated odour analysis

Abstract

This paper describes the design and performance of an automated rapid static headspace sampler and a new axisymmetric temperature- controlled sensor chamber. The system is controlled via a virtual instrument embedded within a microcomputer and is capable of taking several hundred measurements per day. The headspace sampler has a repeatability of better than 1% with a dead-volume of only 3.1 ml and lag time of about 470 ms. The new sensor chamber operated at a constant temperature to better than ± 0.1° and gave a marked improvement in both sensor stability and response time, This new design of analytical instrument should provide for the superior analysis of odorant materials.
