Crude assay is essentially the evaluation of a crude by physical and chemical testing. We can assay the crude to evaluate the boiling range distribution of the cut points or complete a comprehensive characterisation that includes full chemical testing of the various boiling range fractions produced from the distillation.

Detection of trace and ultra trace concentrations of total mercury including crude hydrocarbons, condensates, LPG and gas streams.  IPL utilises two methods of quantification to determine mercury to a limit of quantification of 0.2 ppb ug/kg. 

IPL is the first laboratory in NZ with the capability to perform the required weathering and dispersant testing for oil discharge management plans as regulated by Maritime NZ.
