Total volume was brought to 40 mL with IPA and vortexed for an additional 30 seconds. The sample was then centrifuged for 5 minutes at 3000 rpm. The supernatant was diluted 10-fold in 25:75 water:methanol, vortexed briefly, and filtered using a 0.2 μm Thomson SINGLE StEP standard filter vial (cat.#: 25893) prior to analysis.
