Gas Chromatography Applications
The Tuesday afternoon session on gas chromatography (GC) applications includes three talks from instrument vendors.
The Tuesday afternoon session on gas chromatography (GC) applications includes three talks from instrument vendors.
The first presentation, by Ulrich Gokeler of Siemens, discusses the benefits of transferring routine GC analyses to automatic on-line measurement. Because an on-line approach enables more frequent measurements and repeatable sample conditions, it may be possible to improve process and quality control as well as to minimize safety concerns. The transfer can also lead to cost savings.
The next talk presents the work of a team of scientists from two organizations: Itsuko Iwai, Dave Randle, and Robert Freeman, all of Frontier Laboratories, and Terry Ramus of Diablo Analytical. The talk will discuss the analysis of phthalates using thermal desorption GC combined with mass spectrometry detection (TD-GC–MS). TD-GC–MS is one of the easiest and most accurate methods for phthalate analysis. The talk will focus on the quantitative analysis of regulated phthalates in a sample with high concentrations of unregulated phthalates.
The final talk of the session, by Shawn Wilson of Inficon, will cover refinery gas analysis with temperature-programmable micro GC. Micro GC instrumentation combines microelectromechanical system (MEMS) technology with a modular GC platform to perform parallel analysis on refinery gas samples, significantly reducing the analysis time from the typical 30 minutes of traditional GC to 3 minutes.
This session will be held from 1:00 to 2:20 pm.
Best of the Week: Food Analysis, Chemical Migration in Plastic Bottles, 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.
