Users of liquid chromatography often face difficulties regarding irreproducibility of retention and selectivity in reversed phase HPLC. Very often, the problem lies in poor equilibration of the HPLC column between injection, which in gradient HPLC can affect the separation selectivity as well as analyte retention. Read more

Many drugs of abuse (DOA) — whether natural or synthetic — are rapidly excreted from the human body. However, some can persist for extended periods. Screening for traces of DOAs has become commonplace by analyzing human urine with liquid chromatography–mass spectrometry (LC–MS) or gas chromatography–mass spectrometry (GC–MS) through derivitization of the parent compounds. SPE provides an ideal extraction media for DOA compounds.  Download the app note.
