Development of Needle Trap Technology for On-Site Determinations: Active and Passive Sampling

Asl-Hariri, Saba; Gómez-Ríos, Germán Augusto; Gionfriddo, Emanuela; Dawes, Peter; Pawliszyn, Janusz (ACS, 2014)

This study presents a thorough evaluation of new prototypes of extended tip needle trap devices (NT), as well as their application to in situ sampling of biological emissions and active/passive on-site sampling of indoor ...
New Calibration Approaches in Solid Phase Microextraction for On-Site Analysis

Chen, Yong (University of Waterloo, 2004)

Calibration methods for quantitative on-site sampling using solid phase microextraction (SPME) were developed based on diffusion mass transfer theory. This was investigated using adsorptive polydimethylsiloxane/divinylbenzene ...
