VSMOW2、SLAP2、GRESP、GRESP-4x4ml、IAEA-CH-7、NBS22 Reference Materials Characterized for Stable Isotope Ratios 

List of Reference Materials Characterized for 2H

BS 22 is aimed at δ13C and δ2H calibrations by TC/EA techniques.

NBS 22 mineral oil was prepared by S. Silverman, Chevron Oil Company, La Habra, California [1]. 

NBS-22 has served for several decades as reference material for organic carbon and hydrogen bearing substances. The carbon isotopic composition of this material was re-assessed in δ13C value [2,3].
