Water Analysis by Solid Phase Microextraction Based on Physical Chemical Properties of the Coating

Autor: Angela. Saraullo, Janusz Pawliszyn, Perry A. Martos

Publikováno v: Analytical Chemistry. 69:1992-1998

A novel and simple method using solid phase microextraction (SPME) with poly(dimethylsiloxane) fiber coating and linear temperature-programmed retention index (LTPRI) has been developed to quantify petroleum hydrocarbons in water. Partition coefficie

Estimation of Air/Coating Distribution Coefficients for Solid Phase Microextraction Using Retention Indexes from Linear Temperature-Programmed Capillary Gas Chromatography. Application to the Sampling and Analysis of Total Petroleum Hydrocarbons in Air

Autor: Janusz Pawliszyn, Perry A. Martos, and Angela Saraullo

Publikováno v: Analytical Chemistry. 69:402-408

The paper describes a method to quantify hydrocarbons in air exclusively on the basis of chromatographic parameters without the need for calibration. A simple technique is presented to estimate distribution coefficients (K) between air and the poly(d

Calibration of Solid Phase Microextraction for Air Analyses Based on Physical Chemical Properties of the Coating

Autor: Perry A. Martos, Janusz Pawliszyn

Publikováno v: Analytical Chemistry. 69:206-215

Solid phase microextraction (SPME) with poly(dimethylsiloxane) (PDMS) is used to sample dynamic hydrocarbon standard gas mixtures with calibration for temperature, relative humidity, gas velocities, and gas concentrations. Equilibration times were fo

Sampling and determination of formaldehyde using solid-phase microextraction with on-fiber derivatization

Autor: Janusz Pawliszyn, Perry A. Martos

Publikováno v: Analytical chemistry. 70(11)

Gaseous formaldehyde is sampled by derivatization with o-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine hydrochloride (PFBHA) adsorbed onto poly (dimethylsiloxane)/divinylbenzene solid-phase microextraction fibers. The product of the reaction is an oxime

Issues in mass spectrometry between bench chemists and regulatory laboratory managers: summary of the roundtable on mass spectrometry held at the 123rd AOAC International Annual Meeting

Autor: David N, Heller, Steven J, Lehotay, Perry A, Martos, Walter, Hammack, Amadeo R, Fernández-Alba

Publikováno v: Journal of AOAC International. 93(5)

At the 123rd AOAC International Annual Meeting in Philadelphia, PA, 45 residue chemists gathered for a roundtable discussion of mass spectrometry (MS) used for regulatory chemical residues analysis. The session was conceived to address current techni

Time-weighted average sampling with solid-phase microextraction device: implications for enhanced personal exposure monitoring to airborne pollutants

Autor: Janusz Pawliszyn, Perry A. Martos

Publikováno v: Analytical chemistry. 71(8)

The solid-phase microextraction (SPME) device is used as a time-weighted average (TWA) sampler for gas-phase analytes by retracting the coated fiber a known distance into its needle housing during the sampling period. Unlike in conventional spot samp
