For example, adding 0.1 mL of MOAS to 1 mL of sample would result in a dilution of 90.9% of the original concentration.[3] If a greater salinity is required, this can be accomplished by dissolving solid sodium chloride in the sample to achieve a final salinity of 2% for the protection of Allivibrio fischeri.[3] Highly turbid samples that contain particulate matter will be required to settle before the test can be conducted.[3] Particulate matter in the sample can interfere with bioluminescence by absorbing light and give misleading test results.
