Elemental Microanalysis News

Elemental Microanalysis has added a new gelatin IRMS standard, B2215, to the range of IRMS reference materials available. The new standard is certified for ¹³C, ¹⁵N, ¹⁸O and ³⁴S.

This isotope standard may be particularly useful for those undertaking collagen studies.  A lot of collagen advertised on the web is fully hydrolysed, so it is nothing more than a mixture of amino acids, and in our view unsuitable as a reference material.  Our gelatin reference material is only partially hydrolysed, so retains much of the collagen structure – physically and chemically. Hence it is much more closely matrix-matched to pure collagen.

Our full range of certified IRMS reference materials, all of which are traceable to a primary reference (NIST, IAEA), is shown in the PDF available for download below, as well as our ‘working’ standards, intended as an ‘in-run’ reference.
