Separation Science, in collaboration with Agilent, offers a selection of application notes relevant for forensic analysis using GC or GC/MS. Learn how to perfect your screening techniques for drugs of abuse and speed up your analyses for various forensic samples. Also, in more general terms, learn about the impact of temperature on high-temperature GC columns and adopt some successful strategies for working with high temperature GC applications by simply clicking the buttons below.


Analysis of Drugs of Abuse by GC/MS Using Ultra Inert Universal Sintered Frit Liners
Gas chromatography/mass spectrometry (GC/MS) is a common screening technique for controlled substance analyses.This application note demonstrates how a sintered frit liner offers the same protection from complex nonvolatile matrices as glass wool liners, while avoiding wool breakage that may cause loss of peak response.




Maximizing Efficiency of the Agilent QuickProbe GC/MS System
This application note introduces the Agilent QuickProbe GC/MS system — a novel system for quick analysis of various forensic samples including liquids, powders, tablets, plant materials, and plastics. When used efficiently, the QuickProbe system and its consumables can quickly screen samples such as white powders or other suspected drugs of abuse, possibly reduce backlogs, and allow users to select which samples require confirmation.




Impact of Temperature on the Efficiency of High-Temperature GC Columns
The best practices for performing GC at temperatures above 360 °C are disputed. High-temperature gas chromatography applications using fused silica columns can be problematic for applications that run above 400 °C. This technical overview examines the effects of temperatures above 400 °C on the integrity of the Agilent J&W DB-5ht column phase and brittleness of the column over extended periods of time.



Successful High-Temperature GC with Agilent J&W Deactivated Stainless Steel GC Columns
This technical overview examines successful strategies for working with high temperature GC applications and the implementation of metal GC columns. Agilent UltiMetal and ProSteel GC columns use the same phase as their fused silica counterparts, with the advantage of being able to operate at temperatures up to 430 °C for extended periods
of time.


Analysis of E-Cigarette Liquid by 7890 GC and Intuvo 9000 Using an Agilent J&W DB-HeavyWAX GC Column
This application note demonstrates the use of the Agilent J&W DB-HeavyWAX GC column for the analysis of e-cigarette liquid using an Agilent 7890 and Agilent Intuvo 9000 gas chromatograph. This column has a maximum isothermal temperature of 280 °C and programmed temperature of 290 °C, with increased thermal stability, allowing for the efficient analysis of later eluting and higher boiling compounds.
