High precision Cl, Br and I determination in mineral standards using the noble gas method

Kendrick, Mark

Description

Few techniques are available for analysis of the heavy halogens (Br and I) and characterisation of mineral standards for inter-laboratory comparison is desirable. This study illustrates the noble gas method for precise halogen measurement in neutron-activated samples by laser characterisation of four scapolite gems. The scapolites have Cl concentrations of 3.1-4.1wt.% and a range of Br/Cl and I/Cl ratios that are typical of crustal fluids. Each of the scapolites exhibits some heterogeneity...[Show more]
