In the first analysis, 500 µL of the standard was placed in a maximum recovery pre-slit septa vial. In the second set of analyses, a 300 µL aliquot of sample was placed into five separate vials, each vial capped with non-preslit septa. This ensured that there was no evaporation of the samples over the 10 hours required for the analysis.
