ADDING MULTIMEDIA Bruker Daltonics Introduces Sensitive, Five Minute Melamine Food Safety Testing Solution Based on Robust & ...

Bruker Daltonics today has released a robust, fast and highly
sensitive high-capacity ion trap HCT� solution for the detection
and quantification of melamine and cyanuric acid (CA) by food
safety laboratories. Since September 2008, thousands of infants and
young children in China have been hospitalized to treat the
symptoms caused by the ingestion of melamine and CA contaminated
infant formula and related dairy products. Previously in 2007, pet
food, animal feed wheat gluten and other protein-based foods were
found to contain residues of melamine and CA. A five minute,
accurate LC-MS/MS analysis method has been developed by Bruker
Daltonics� food safety development laboratory in Australia. This
robust, easy-to-use and cost-effective method for the extraction,
detection and quantification of melamine and CA uses the speed,
sensitivity and excellent quantitative capabilities of the
high-capacity ion-trap mass spectrometer HCTultraTM, hyphenated
with a Dionex UltiMateTM 3000 LC system and AcclaimTM Mixed-Mode
WAX-1 column. The method is capable of detecting melamine in
various matrixes well below the concentrations required by various
food safety and other regulatory authorities around the world, such
as the limits set by the U.S. Food and Drug Administration (FDA) of
1 ppm for melamine and cyanuric acid in infant formula, and 2.5 ppm
for other foods. Dr. Matthias Pelzing, Asia-Pacific Applications
Manager for Bruker Daltonics, explained: �We recommend LC-MS/MS
methods due to their straight-forward sample preparation, compared
to GC-MS methods which often require sample derivatisation. With
our new routine analysis method we have demonstrated that melamine
can be detected down to trace levels of 0.05 ppb, and that it is
possible to quantify melamine at concentrations relevant to various
international food authorities in 5 minutes.� Mr. Clive Seymour,
Executive Vice President of Bruker Daltonics, commented: �Due to
its robustness, ease of use, small footprint and lower cost, our
HCT ion trap-based solution offers significant practical and
operational advantages over traditional triple-quad MRM approaches.
In addition, the superior full scan sensitivity of our unique HCT
ion trap technology offers not only outstanding detection limits
for melamine and CA, but also the option of full-scan
identification of other unknown, new or modified food contaminants
with superior sensitivity.� The new Bruker Application Note #
LCMS-49 on melamine and CA analysis is available in English,
Chinese, Korean, Thai and Japanese, and can be down-loaded at
