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.
Modern HPLC Strategies: Improving Retention and Peak Shape for Basic Analytes
August 16th 2024In high-performance liquid chromatography (HPLC), it is common for bases and unreacted ionized silanols on silica-based columns to cause irreproducible retention, broad peaks, and peak tailing when working with basic analytes. David S. Bell, Lead Consultant at ASKkPrime LLC offers innovative HPLC strategies that can help mitigate such issues.
Characterizing Cooked Cheese Flavor with Gas Chromatography
September 19th 2024A joint study by the Department of Food and Nutritional Sciences at the University of Reading and Synergy Flavours aimed to identify volatiles that contribute to the aroma of cooked cheese, including the role of fat content in development during cooking.
