Environmental Analysis with GC–MS
This session will be presided over by Ibolya Molnar-Perl of L Eotvois University.
Session 1100
Room 119B
This session will be presided over by Ibolya Molnar-Perl of L Eotvois University.
Adrienne Brockman of Penn State University will kick off the session with a talk on the analysis of wastewater samples for characterization of drug usage.
Molnar-Perl, the session host, will discuss the determination of steroids in the Danube River. Joaudimir Castro Georgi will complete the first half of the session with a presentation on mercury speciation with GC-ICP-MS.
Several talks will cover the analysis of volatile organic compounds. Daniel Y. Pazo of the Centers for Disease Control and Prevention (CDC) will present an automated method for the analysis of VOCs in cigarette smoke by SPME-GC-MS. Fallon Moliere, also from the CDC, will discuss the measurement of VOCs in urine by isotope dilution internal standardization. And Ilaria Ferrante of Dani Instruments will address the use of dynamic headspace for VOCs at trace levels in environmental matrices.
Following the break, Melinda T. Pham of Penn state will present a high-throughput environmental forensic study for identifying sources of polycyclic aromatic hydrocarbons (PAHs). The session will wrap up with a presentation by Karl Organtini of Penn State of the analysis of native compounds generated during combustion and their metabolites.
Best of the Week: Food Analysis, Chemical Migration in Plastic Bottles, STEM Researcher of the Year
December 20th 2024Top articles published this week include the launch of our “From Lab to Table” content series, a Q&A interview about using liquid chromatography–high-resolution mass spectrometry (LC–HRMS) to assess chemical hazards in plastic bottles, and a piece recognizing Brett Paull for being named Tasmanian STEM Researcher of the Year.
Using LC-MS/MS to Measure Testosterone in Dried Blood Spots
December 19th 2024Testosterone measurements are typically performed using serum or plasma, but this presents several logistical challenges, especially for sample collection, storage, and transport. In a recently published article, Yehudah Gruenstein of the University of Miami explored key insights gained from dried blood spot assay validation for testosterone measurement.
Determination of Pharmaceuticals by Capillary HPLC-MS/MS (Dec 2024)
December 19th 2024This application note demonstrates the use of a compact portable capillary liquid chromatograph, the Axcend Focus LC, coupled to an Agilent Ultivo triple quadrupole mass spectrometer for quantitative analysis of pharmaceutical drugs in model aqueous samples.
