New IRMS standards expands analytical capabilities

Expanded line offers 26 options

Elemental Microanalysis, a leading global supplier to the elemental analysis market, is pleased to announce the release of five additional IRMS standards. 

Elemental's R&D development expert in isotopic ratio mass spectrometry, David Castle, and his team, have brought five IRMS reference material standards to market: an additional caffeine, two glucose, and two gelatin IRMS. This analyser calibration offering expands Elemental’s isotope reference material range to a total of 26 products, including: wheat flour, sorghum flour, olive oil, silver phosphate, and water.

The two glucose standards are derived from differing plant types, wheat (B2217, a C3 type) and cane sugar (B2218, a C4 type), to provide different ¹³C values, offering two anchor points for simple carbon isotope analysis.

The two gelatin standards are certified for C, N, and S isotopes. One example of their use is for isotope bioarchaeologists who may want to analyse collagen in ancient bones. The two new gelatin standards, cold-water fish gelatin (B2219) and bovine gelatin (B2222), add to the existing warm-water fish gelatin standard from Elemental (B2215) offer a broad spread of isotopic values. One additional unique factor of B2222 is that the cow which provided the bovine gelatin standard was primarily fed maize (a C4 type plant) its whole life.

The IRMS product range from Elemental Microanalysis provide compatible products for analysers such as the isoEArth⁺ from Sercon; full product details are in the newly published Micro & IRMS catalogue. Request a copy today.
