High Throughput Analysis for On-site Sampling
Gomez-Rios, German Augusto (University of Waterloo, 2012-12-12)Until recently, multiple SPME fibres could not be automatically evaluated in a single sequence without manual intervention. This drawback had been a critical issue until recently, particularly during the analysis of numerous ... -
Open Port Probe Sampling Interface for the Direct Coupling of Biocompatible Solid-Phase Microextraction to Atmospheric Pressure Ionization Mass Spectrometry
Gomez-Rios, German Augusto; Liu, Chang; Tascon, Marcos; Reyes-Garcés, Nathaly; Arnold, Don W.; Covey, Thomas R.; Pawliszyn, Janusz (American Chemical Society, 2017-04-04)In recent years, the direct coupling of solid phase microextraction (SPME) and mass spectrometry (MS) has shown its great potential to improve limits of quantitation, accelerate analysis throughput, and diminish potential ... -
Solid Phase Microextraction On-Fiber Derivatization Using a Stable, Portable, and Reusable Pentafluorophenyl Hydrazine Standard Gas Generating Vial
Poole, Justen J.; Grandy, Jonathan J.; Gomez-Rios, German Augusto; Gionfriddo, Emanuela; Pawliszyn, Janusz (American Chemical Society, 2017-07-05)Solid phase microextraction (SPME) on-fiber derivatization methods have facilitated the achievement of lower detection limits and targeted analysis of various substances that exhibit poor chromatographic behavior, thermal ... -
Strategies for the Direct Coupling of Solid Phase Microextraction to Mass Spectrometry
Gomez-Rios, German Augusto (University of Waterloo, 2017-09-27)In recent years, advances in direct sample to mass spectrometry (MS) techniques have allowed for the application of these methods towards quantitative analysis in complex matrices such as biofluids and tissue. However, the ...
