Comparison of SPE vs. SLE for the Quantitative Analysis of Anabolic Steroids in Serum Using LC-MS/MS
Author(s)Danielle Mackowsky
UCT’s approach for the analysis of anabolic steroids from serum utilizes a traditional reversed phase interaction, but also features the addition of strong-anion exchange functionality (QAX) within the sorbent. This added functionality aids in the removal of unwanted matrix components commonly found in serum such as amino acids and inorganic ions. To prove the effectiveness of this approach, a comparison study was conducted using UCT’s recommended sorbent for steroid analysis (C8 + QAX) versus a traditional SLE, diatomaceous earth sorbent.
