1 - This does not include the volume necessary to perform MS/MSD analyses. Include additional sample (normally 3 times the quoted volume or mass) for each sample requiring an MS/MSD. This extra sample volume should always be included for at least one sample in sample sets of 5 or greater. Contact the laboratory for more information.
