			Ionic Fluids for Microextraction in Forensic Toxicology In order to accurately quantify the concentration of trace analytes within a complex mixture, appropriate sample preparation is imperative. Some of the most common pretreatment methods that are used prior to analysis by high-performance liquid chromatography (HPLC) or gas chromatography with mass spectrometry (GC-MS) include liquid-liquid extraction (LLE) and solid phase extraction (SPE).

			Spatial Gradients in Cannabis and Concerns for Medical Use Researchers have uncovered how cannabinoid profiles that vary within the same Cannabis plant can elicit organ-specific effects in the plant itself. This in-planta variability means stringent standardization is required before Cannabis can be implemented as a therapeutic crop for modern medicine.

	Lifestyle Profiling as a Forensic Analysis Technique Lifestyle profiling represents a new method where the chemistries that are obtained from the personal objects of a person are used to build their lifestyle profile. This is then used to infer the person’s location and characteristics which are further applied to various forensic investigations.

	What is Shotgun Lipidomics? Lipidomics refers to the study of cellular lipidomes, meaning the network of lipid constituents that maintain cellular and bodily health. Shotgun lipidomics follows these networks of lipids within biological systems on a larger scale, allowing identification, quantification, and interaction of lipids to be studied.

	Revealing the Molecular Basis of Fragrances using Gas Chromatography Fragrances are important characteristics of food and wellness products. Understanding the science behind fragrances remains a complex challenge, as a multitude of odorant molecules act together to give a characteristic fragrance.

	Combating Counterfeit Green Tea with Metabolomic Profiling Green tea is a popular beverage that has traditionally been produced in several Asian countries. The origin of green tea is a key market factor for consumers, and this has led to a surge in counterfeit tea products. Thus, methods that can be used to authenticate green tea are in high demand.

	Authenticating Complex Herbal Products using Liquid Chromatography Many natural products contain pharmaceutically active ingredients, and the demand for healthy herbal products is high. This is related to their use as drugs in traditional medicine such as Ayurveda, an Indian branch of traditional medicine, as much as to the global demand for healthy herbal food supplements.
