The Biochrom 30 is a dedicated amino-acid analyser that is said to be suitable for the busy industrial QC laboratory running 24 hours a day, seven days a week.
The Ninhydrin detection/ion exchange chromatography method is compliant with European Union (EU) commission directive 98/64/EC and the AOAC method for the determination of free and total amino-acid content in food and feedstuffs.
Biochrom claims that both the instrument and the method are robust, easy to use and economical to run.
The column has a long life, is acid and base resistant and is fully compatible with possible high concentrations of salts.
It can be fully regenerated and re-optimised, enabling years of usage, controlled costs and minimising waste.
A range of sample types can be run and, thanks to the online post-column derivatisation of the amino acids with Ninhydrin, the precision on-peak area is better than 1.5 per cent RSD.
The peak separation is more than 95 per cent on a common amino-acids profile (up to 45 amino acids in a single run with lithium systems), including Taurine and Ornithine, oxidised amino acids such as Cysteic acid and Methionine Sulfone and hydroxylated amino acids such as Hydroxyproline and Hydroxylysine.
There is a choice of two buffer systems available; both are optimised for food and feedstuff analysis, including an accelerated buffer system for high-sample-throughput laboratories.
Short methods are available for specific applications such as Lysine or Taurine content and there is a range of accessories to analyse Polyamines.
Technical and scientific support is available worldwide from a dedicated amino-acid analysis support team.
