To date, sample preparation of solid materials requiring ultrasonic extraction has mostly been performed manually. This is in part due to the fact that automation of the sonication step has not previously been available; however, another reason is that the solid particulate can create a suspension in the extraction solvent, which can easily block a syringe, making automated collection of the extract and subsequent injection to the GC or LC unreliable.

Comprehensive automation of the solid phase extraction gas chromatographic mass spectrometric analysis (SPE-GC/MS) of opioids, cocaine, and metabolites from serum and other matrices

Comprehensive automation of the solid phase extraction gas chromatographic mass spectrometric analysis (SPE-GC/MS) of opioids, cocaine, and metabolites from serum and other matrices

Posted 3 years ago

The determination of opioids, cocaine, and metabolites from blood serum is a routine task in forensic laboratories. Typical methods include many manual or semi-automated steps like protein precipitation, dilution, solid phase extraction, evaporation, and derivatization preced¬ing GC/MS or LC/MS analysis.
