Kui üksikmeetodil ei ole piisavat spetsiifilisust, tuleb see saavutada sobivate puhastusmeetodite, kromatograafilise lahutamise ja spektromeetrilise detekteerimise kombineerimisega.
If a single technique lacks sufficient specificity, the desired specificity may be achieved by analytical procedures consisting of suitable combinations of clean-up, chromatographic separation(s) and spectrometric or immunochemical detection, e.g. GC-MS, LC-MS, IAC/GC-MS, GC-IR, LC-IR, LC/IMG.
