The detection limit for samples is nominally 20 ppb, with modification lower limits can be achieved, please contact us to discuss your requirements. 

DetectORE™ results are reported in detectORE Units (“dU”), which is a measurement of the amount of gold extracted from a sample.  The dU is directly proportional to the amount of gold in a sample and can be converted to ug/kg (i.e. ppb or ppm).
