13 Steroids – 2 panels – 1 analytical column
With 96 SPE Well Plate

* Required Fields


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 sample clean up procedure in 96 SPE well plates. 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


  • Equilibrate Steroid 96 SPE plate with 0.8 ml
  • Equilibration Reagent 1 into each well.
  • Centrifuge 1 min at 200 x g.
  • Repeat with 0.8 ml Equilibration Reagent 2.


SPE clean up procedure

  • Pipette 500 μl research sample/calibrator/MassCheck® control, 50 μl Internal Standard Mix and 450 μl Extraction Buffer into each well of the Steroid 96 SPE plate.
  • Vortex for 2 min at 600 rpm.
  • Add 1 ml Wash Buffer into each well, centrifuge for 1 min at 200 x g and repeat.
  • Centrifuge for 2 min at 3000 x g to dryness, discard effluent.
  • Place plate onto the steroid collection plate.
  • Add 500 μl Elution Buffer and centrifuge for 1 min at 200 x g.


Clean-up and injection

  • Place steroid collection plate under nitrogen at 45°C and evaporate the eluates.
  • Add 100 μl Reconstitution Buffer into each well.
  • Shake collection plate for 2 min at 900 rpm.
  • Centrifuge 5 min at 3000 x g.
  • Seal collection plate with adhesive seal, transfer to autosampler.
  • Inject 10–40 μl eluate into the LC-MS/MS system.
