For evaluating the device,
seven anabolic steroids (prasterone, 5-androstane-3, 17-diol, methandriol, 19-norandrostenediol,
androstenediol, methyltestosterone and methandienone) were used as model analytes and extraction
conditions such as type and volume of organic solvents, agitation speed, extraction time, extraction temperature
and salt addition were studied in detail
