Method Reference:
GB 5009.259-2016

Method Description:
Samples are weighed out to 10g and are then pipetted out into a dilution series according to a dilution matrix. Buffer and an inoculum are added to the tubes in the dilution series and the samples are then incubated at 36±1°C for 18 to 21 hours. Standards are also prepared alongside the samples. Once incubated the samples are pipetted into 96 well assay plates and read for absorbance on a plate reader. This result is then translated into a concentration. A standard curve is also created using the standards prepared alongside the samples.
