Ninhydrin Formulation for Ion Exchange Chromatography Systems Improves Amino Acid Analysis

Biochrom has launched its EZ Nin Reagent, a ready-to-use ninhydrin formulation for use in ion exchange chromatography systems with post-column derivatisation for improved amino acid analysis.

The newly launched and patent protected EZ Nin Reagent has been developed to save laboratory time and waste; it requires no mixing or nitrogen and does not degrade with time or exposure to oxygen, providing reliable analysis over time without loss of sensitivity. Challenges encountered with standard ninhydrin include the long preparation process, instability of the reagent, degradation and waste and batch-to-batch variability. Each batch of EZ Nin Reagent is identically prepared, enabling the reagent to be topped up on the instrument, eliminating waste or the risk of running out during a series of analyses. EZ Nin Reagent is methanol and hydrindantin free.

Tristana von Will, Product Marketing Manager at Biochrom, commented: “Biochrom’s formulation combines ease of use with unprecedented chemical stability, providing laboratories with the confidence they require when evaluating concentrations of amino acids for diagnosis and monitoring of inborn errors of metabolism.”
