Qa³ has made a significant investment in the development and validation of methodology for the determination of arsenic and phosphorus in hydrocarbon gas and gas condensates. One outcome of the research has resulted in a solid phase sorbent trap designed by Qa³ to capture arsenic and phosphorus species selectively. These traps can be supplied to clients to perform the sampling themselves and then return the traps to the Qa³ laboratories for analysis by USN-ICP-OES.
For an in-depth study, e.g. where a mass balance across a facility is required, or if the client does not have any trained sampling technicians, Qa³ personnel can be contracted to perform the on-site sampling.
If required, the methodology developed by Qa³ can achieve a detection limit of as low as 0.1 ppb in gas.
