Automated preparation of matrix matched pesticide calibration standards in QuEChERS food extracts combined with filtration and LC/MS analysis.
Using liquid chromatography, NIST researchers have doubled their database of oligosaccharides in milk, which they say could help infant formula manufacturers to develop optimised products.
Application Note: Determination of thirteen beta agonists in pork using ultra high-performance liquid chromatography – Tandem Mass Spectrometry
PerkinElmer evaluate the administration of beta-agonists as growth-promoting agents in food-producing animals.
Application Note: Determination of stevioside and rebaudioside A in stevia leaves, beverages and food additives using HPTLC-MS
High Performance Thin Layer Chromatography coupled with Mass Spectrometry (HPTLC–MS) is a very useful analytical technique where samples can often be analysed with a minimum of sample preparation.
Researchers have developed a method to determine the chemical 'fingerprint' of chocolate, in order to accurately track its origin and detect fraudulent activity across its supply chain.
Application Note: Using the MALDI Biotyper® for microbial identification at the China Center of Industrial Culture Collection (CICC)
Matrix assisted laser desorption/ ionization time-of-flight mass spectrometry (MALDI-TOF MS) with the MALDI Biotyper® (MBT) is used at the China Center of Industrial Culture Collection (CICC) to identify strains.
To help meet the increased demand in testing of anionic polar pesticides, this webinar will provide essential insight into conquering this analysis on a routine UPLC-MS/MS platform.
QuEChERS has become the most important analytical method in routine pesticide labs for food and feed samples. In particular, nearly all types of fruits and vegetables are analysed with this methodology worldwide for several hundred pesticides applied in agriculture.
The business of contract testing labs in terms of feed and food contaminants is driven by five main topics which at the end contribute to a real positive growth of this niche market. These topics are: 1) Of course regulations oblige goods producers to deliver safe products to the market…
In 2004 the US Food and Drug Administration (FDA) passed a law that describes the requirements for allergen labelling and customer protection (Public law 108 – 282 Title II).
