The Analysis of Chlorinated Dioxins, Difurans, and Polychlorinated Biphenyls in Edible Oils
February 1st 2016Analysis of the six matrices processed yielded acceptable recoveries for all analytes with standard deviations below 20%. Analysis of an n-hexane blank sample resulted in no detectable target analytes measured within the calibration range of each respective compound.
Analysis of Amino Acids in Oxidized and Unoxidized Feed Samples
February 1st 2016Commission Regulation (EC) No 152-2009 published in the official Journal of European Union laid down the methods of sampling and analysis for the official control of feed. The Regulation describes methods of analysis to control the composition of feed materials and compound feed products. Establishing the amino acids profile is an important way to control quality and nutritional value of feeds.
Quantification of Purine Alkaloids and Catechins in Green and Black Tea Using Comprehensive 2D-LC
December 1st 2015Comprehensive 2D-LC enables the analysis and quantification of purine alkaloids and catechins in green and black tea. As expected, green tea contained higher amounts of the catechins epigallocatechin gallate and epicatechin than black tea.
New Method for Sampling and Analysis of Electronic Cigarette Aerosols
December 1st 2015Following sampling, tubes were transferred to a Markes UNITY™ thermal desorption system paired with an Agilent 7890B GC that was coupled to an Agilent 5977A MS detector. The UNITY™ system and GC–MS parameters are presented in Table I and Table II, respectively.
Mycotoxin testing awareness has increased as countries involved in world trade of raw agriculture and processed consumer products rely on a safe global food supply
Arsenic Speciation on Hamilton PRP-X100
June 1st 2015Organic arsenic compounds added to feed stocks of chicken and poultry pose serious environmental and ecological threats. National and worldwide health organizations, such as the United States Environmental Protection Agency and the US Food and Drug Administration, have recently implemented more stringent concentration limits for arsenic species in drinking water and foodstuffs.
Automated Solid Phase Extraction for Efficient Extraction of Fluoroquinolone Antibiotics from Fish
The global demand for fish as a natural source of fresh animal protein, essential fats, minerals, and vitamins continues to rise with the human population.
Analysis of Diacetyl and Other Vicinal Diketones (VDKs) in Alcoholic Beverages
February 1st 2015Vicinal diketones (VDKs) are naturally produced compounds in the fermentation process. The monitoring of VDK levels is of great importance as the concentration of these compounds can greatly alter the flavor of a beverage.
Simultaneous Analysis of Vitamins B1, B2, B3, and B6 in Protein Powders and Supplements
February 1st 2015B vitamins are a group of water soluble vitamins that play an important role in cell metabolism. This group consists of a number of compounds including thiamine (vitamin B1), riboflavin (vitamin B2), niacin and nicotinamide (vitamin B3), and pyridoxine and pyridoxal (vitamin B6).
