Peak Performance in Chromatography

摘要

Feeling inundated with the alphabet soup of today's chromatography methods? Join the crowd. Gas chromatography (GC) and liquid chromatography (LC) are still the meat-and-potatoes basis for separating mixtures and purifying compounds, but the techniques rarely exist in a pure state. Instead, variations on the GC and LC themes dominate the field: high-performance LC (HPLC), fast GC, and reversed-phase LC (RPLC) are common. Hyphenated techniques that combine a chromatographic method with a different analytical technique such as mass spectroscopy (MS) abound: GC-MS, GC coupled to ion-trap MS (GC-ITMS), and HPLC-MS pepper the analytical chemistry landscape.
