Pre Treatment Note: Sample Pretreatment Step
Enzymatic Hydrolysis: To 300 uL urine add 75 uL of 300 mM ammonium acetate (pH 4.0) and 25 uL of -Glucoronidase solution (100,000 units/mL (www.campbellscience.com, DR2100).
Mix and vortex for 30 secs. Incubate at 37- 40°C for 60 minutes. (Gentle shaking during this step is recommended). After incubation, bring samples to room temperature prior to extraction.
Extraction Procedure:
Sample Loading: Load the sample (~400 uL) from pretreatment step onto the Novum plate and apply a short and gentle pulse of vacuum (~5-10 sec and 5"or less of Hg) until the sample has completely entered in the media.
NOTE: Avoid prolonged or excessive vacuum. The sample must not leave the Novum bed.
Wait for 5-6 minutes. NOTE: Inadequate or excessive wait period will lead to variable recoveries and poor precision.
Elution: Dispense 900 uL of ethyl acetate onto the Novum plate and collect the solvent under force of gravity (approximately 5 min).
Repeat with another 900 uL addition of ethyl acetate and collect the solvent under gravity.
Apply vacuum at 5" of Hg (or lower) for 20-30 secs to complete the extraction.
NOTE: Excessive/Prolong application of the vacuum may force the elution of plasma and cause dirty extraction
Dry down: Evaporate extracted samples to complete dryness under slow stream of N2 and room temperature.
Reconstitute the dry residue in 200 uL of initial mobile phase containing internal standard |
