Headspace Liquid-Phase Microextraction Solvent Vapor Pressure
A research group from Yanbian University and the Key Laboratory of Organism Functional Factors of the Changbai Mountain (both Yanji City, Jilin Province, China) examined the effect of the vapor pressure of the extracting solvent on the enrichment factor in headspace liquid-phase microextraction.
A research group from Yanbian University and the Key Laboratory of Organism Functional Factors of the Changbai Mountain (both Yanji City, Jilin Province, China) examined the effect of the vapor pressure of the extracting solvent on the enrichment factor in headspace liquid-phase microextraction. They tested seven extracting solvents with different vapor pressures, and found that the extracting solvent’s vapor pressure dramatically affects the enrichment factor. The factor was found to increase with a decrease in the solvent’s vapor pressure. They validated the result for volatile organic compounds such as polynuclear aromatic hydrocarbons, organochlorine pesticides, and polychlorinated biphenyls.
Gulf Coast Conference: Increasing Density and Viscosity Throughput with Difficult Samples
October 19th 2023Daniel Wolbrecht, senior technical sales consultant at Anton Paar, held a workshop at the Gulf Coast Conference in Galveston, Texas, focusing on how heated autosampler units can help analyze difficult samples.
