LC-MS/MS Analysis of Emerging Food Contaminants Identification of Artificial Colors and Dyes in Food Samples using LC-HR-MS/MS
Analytical methods used to test for the presence of banned colors and dyes in food include TLC-UV/VIS, LC-UV/VIS, and LC-MS. Such methods have limited selectivity and sensitivity and are therefore only used for target analysis. Recent advancements in LC-HR-MS technology provide the ability to perform targeted and non-targeted screening in food samples on a routine basis. The exact mass and MS/M...
متن کاملStudies on the Metabolism and the Detectability of Camfetamine in Rat Urine Using GC-MS and LC-(HR)-MS Techniques
N-methyl-3-phenyl-norbornan-2-amine (camfetamine; CFA) is sold as a so-called "research chemical" via the internet and belongs as an amphetamine-type stimulant (ATS) to the group of new psychoactive substances (NPS). CFA is an analogue of N-ethyl-3-phenyl-norbornan-2amine (fencamfamine; FCF), which was developed in the 1960’s as an appetite suppressant and a stimulant for treating depressive da...
متن کاملIn vivo and in vitro metabolism studies of glaucine, a new herbal high by GC-MS, LC-MS, LC-HR-MS, and NMR techniques
The isoquinoline alkaloid Glaucine was described as an ingredient of legal highs and gained the interest of clinical and forensic toxicologist. So far, only few data on its pharmacokinetic properties was investigated. The aims of the present studies were to elucidate the metabolic fate of glaucine in vivo (rat) by GC-MS and LC-HR-MS techniques, to confirm the human main phase I metabolites in v...
متن کاملDetermination of trace elements in filtered suspended marine particulate material by sector field HR-ICP-MS
Quantification of particulate (w0.45 mm) and dissolved (v0.45 mm) trace elements in seawater is imperative for understanding geochemical cycling in the marine environment. Suspended particulate trace element concentrations are typically v10% of total element concentrations in seawater. To overcome analytical difficulties associated with low analyte concentrations, it is common to filter large v...
متن کاملMeibomian Gland Changes in the Rhino (hr^hr*) Mouse
The rhino mouse, a single gene recessive mutation, is characterized by abnormal epidermal differentiation and maturation leading to the loss of hair at 1 month of age as well as follicular and epidermal hyperkeratoses. We evaluated the lids and corneas of nine rhino mice and their normal litter mates at various ages from 3 months to 1 year. Tissue specimens were studied by light microscopy, sca...
