13 Steroids – 2 panels – 1 analytical column
With Sample Clean Up Columns


The MassChrom® Steroid reagent kit allows the quantitative determination of 13 steroid hormones in serum/plasma by LC-MS/MS. Sample preparation is the same for both steroid panels using an optimised and efficient SPE procedure with sample clean up columns. The use of stable isotope-labelled internal standards for every single analyte ensures reproducible and reliable quantitation of the steroids. The 6PLUS1® multilevel calibrators offer additional precision, and the method also does not require a high-end LC-MS/MS system to be carried out.

Sample Preparation


  • Put Sample Clean Up Columns into tubes for sample preparation.
  • Pipette 0.8 ml Equilibration Reagent 1 into each Sample Clean Up Column.
  • Centrifuge 1 min at 200 x g, check for complete run through, discard effluent.
  • Repeat with 0.8 ml Equilibration Reagent 2.

Sample preparation with Sample Clean Up Columns

  • Pipette 500 μl of the well homogenised research sample/calibrator/MassCheck® control into each Sample Clean Up Column.
  • Add 50 μl Internal Standard Mix and 450 μl Extraction Buffer and homogenise (vortex slightly for 15 seconds).
  • Centrifuge 1 min at 200 x g, check for complete run through, discard effluent.
  • Add 2 x 1 ml Wash Buffer and centrifuge 1 min at 200 x g respectively.
  • Centrifuge 2 min at 3000 x g to dryness, discard effluent.
  • Put labelled autosampler vials with conical bottom into tubes for sample preparation, then put Sample Clean Up Columns on top.
  • Add 500 μl Elution Buffer and centrifuge 1 min at 200 x g.

Concentration and injection

  • Evaporate eluates in the labelled autosampler vials under nitrogen or compressed air at 45°C to dryness.
  • Reconstitute with 100 μl Reconstitution Buffer in the labelled autosampler vials, then close using crimping pliers and vortex for 15 sec.
  • Centrifuge 5 min at 15000 x g.
  • Transfer to autosampler.
  • Inject 10–40 μl of eluate into the LC-MS/MS system.
