National Pollution Inventory NPI (1999 - 2009)

Dioxin and Furan emissions have been measured from several industrial sites in South Australia using USEPA Method 23 and 23A. Results generally conform with the European standard of 0.1 ng/Nm3.
Samples are analysed by the Australian Government Dioxin Laboratory in Sydney or by Assure Quality in New Zealand.

Zinc smelter Gas Train Surveys (1998-9)

A gas sampling system was set-up to cope with high dust loadings at temperatures up to 1100°C and velocities to 30m/s. Gas analyses were made by both IR and EC instruments, with data acquired from up to 5 sites spread over 80 metres of ductwork simultaneously.

Large-scale seabed search (1994-5)

 A large-scale search was carried out in Gulf St Vincent, South Australia to locate a submerged vessel. The initial search area exceeded 500km2 with water depths ranging to 40 metres. Sidescan sonar coupled with magnetometer was used on a grid search, with a line spacing of 700metres and DGPS navigation to 4metres. A target was located after 120 hours of survey and identified for the client by detailed sonargram. Total survey cost was <$50,000.

Continuous Emission Monitoring Systems (CEMS) 2012

A third portable CEMS unit was brought on-line in 2008. The Horiba PG-250 unit measures NOx, SO2, CO, CO2 and O2 using chemiluminescence and non-dispersive infra-red. It meets all USEPA requirements for backup CEMS. NATA calibration gas standards ensure accuracy and dilution probes cope with wet (>20% moisture) and high (>1%) SO2, high (>20%) CO2 gas streams. Logging is via RS-232C interface to user specification.

A Thermo 60i CEMS unit was commissioned to complement the Horiba units. Data logging is to client specification.
