Guidelines for Successful SFC/MS n the early days of on-line LC/MS, Arpino likened the union of these two instruments to the unlikely marriage of a bird and a fish: "Many believe this coupling is even more difficult to achieve than the love-match ... between two creatures that are at ease in their own environments but are not at home in both" (1). At first consideration, this combination of high-pressure and vacuum techniques does seem preposterous. Removing a molecule from its high-pressure solvent, transporting it preferentially over vaporized solvent to a partial vacuum, and imparting a charge on the analyte does seem a challenging feat. However, great progress was made and LC/MS applications have become routine.But what if the analyte were dissolved in a fluid that, at high pressure, solvated like a traditional liquid but transformed to an easily removed gas when the pressure dropped, leaving the analyte free to "fly like a bird"? This was the promise offered by supercritical fluid chromatography (SFC)/MS when research in the area began in the late 1960s (2-5). Admittedly, the analogy should not be carried too far. Nevertheless, the commonly used mobile phases in SFC/MS, such as C02, are much more easily pumped from a high to moderate vacuum system than are

“…Packed column supercritical fluid, subcritical fluid, and enhanced fluidity liquid chromatographies have been used to separate low-MW polymeric and oligomeric mixtures in the past [5][6][7][8]. While these three techniques are different, they are closely related and require the same instrumentation.…”

The utility of low viscosity mobile phases and long chromatographic columns for complex polymer analysis is demonstrated. We use long column supercritical fluid chromatography/ mass spectrometry (SFC/MS) with electrospray ionization (ESI) to characterize a variety of complex, low molecular weight polymers. When quantitative analysis is desired, the resulting three-dimensional (time, intensity, and mass-to-charge ratio [m/z]) data are converted to images. Custom image analysis software is used to detect and integrate peaks in arbitrarily defined regions of the time-m/z map. These integrated peak volumes can be used to quantitate distinct component classes of the polymer mixtures. (J Am Soc Mass Spectrom 2002, 13, 1195-1208
