F
fast gas chromatography (FGC) Uses very short capillary
columns (£10m) that are encased in a stainless steel mesh housing
that fits snuggly around the column. The housing is ballistically heated
(up to 20°C/s), thereby cutting run times by up to 80%. Temperature
re-equilibration is also decreased (there is not a large oven volume
from which to dissipate heat).
A capillary GC column is housed within the braided metal sheath. Because heat is
transferred extremely quickly to the column in this configuration very steep tem-
perature gradients are attainable.
fast liquid chromatography (FLC) Uses short (£5cm) and
narrow (£3mm) columns containing 3 to 5-mm particles to produce
separations that range from seconds to a few minutes.
fast protein liquid chromatography (FPLC) A low-pressure
technique used to separate proteins.
