Do you have experience with gas chromatographs and mass spectrometers, particularly in the identification and analysis of VOCs? Are you knowledgeable in the human odour spectrum and its chemical components? Have you got a laboratory with GC–MS capability?
Do you have experience with gas chromatographs and mass spectrometers, particularly in the identification and analysis of VOCs? Are you knowledgeable in the human odour spectrum and its chemical components? Have you got a laboratory with GC–MS capability? Then the US department of homeland security (DHS) may be interested in your help catching terrorists.
According to the DHS, their science and technology directorate is seeking sources to potentially expand its set of biometric screening tools for deceptive individuals by investigating the possibility of using the human odour signature as an indicator for deception.
At this initial stage the directorate is just looking into performing a proof-of-principle study to determine if human odour signatures can identify the liars. Additionally, this study will examine the human odour samples for evidence to support the theory that their odour signature can be used identify an individual in a manner similar to fingerprinting.
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.
