Abstract
On-line coupling of capillary GC with ICP-MS using the recently commerciali
zed high-temperature interface was developed for the investigation of speci
ation of arsenic in gas condensates. Arsenic was present as a number of spe
cies, the two most abundant species being identified by retention time matc
hing with standards such as triphenylarsine (Ph3As) and triethylarsine (Et3
As). The calibration graph, obtained for Ph3As, was linear up to 100 ng mL(
-1) and the detection limit was 0.05 pg (as As). The arsenic speciation was
found to undergo a slight evolution as a function of sample storage time.
Spiking with standards was found to change the equilibrium in the system.
