(a)= Estimate isotope ratios at low concentrations **= Samples with ratios of 13C/12C>0.0112372 are positive; < 0.0112372 are negative values. %oVPDB= The standard is defined as 0%o. For carbon, the international standard is Pee Dee Belemnite, a carbonate formation whose generally accepted absolute ratio of 13C/12C is 0.0112372.
