|Particle Size:||2.7 µm|
|Pore Size:||90 Å|
|Guard Column:||UltraShield UHPLC precolumn filter, 0.2 µm frit (cat.# 25809)|
|Diluent:||0.1% Formic acid in water|
|Conc.:||A 500 ng/mL standard was prepared in urine. 50 µL of the standard was diluted with 950 µL of a working internal standard (25 ng/mL EtS-d5/100 ng/mL EtG-d5 in 0.1% formic acid in water). The sample was vortexed at 3,500 rpm for 10 seconds to mix. The sample was then centrifuged at 3,000 rpm for 5 minutes at 10 °C. The autosampler needle was adjusted to inject from the supernatant.|
