132 MONOLITHIC SUPPORT

monolithic support Monolithic supports are based on the pro-
duction of a unitary porous structure formed in situ and thereby
exactly conforming to the column housing.
monomeric bonded phase A monomeric bonded phase has
individual moieties chemically attached to one binding site on the
support surface. These supports are commonly prepared from
monochloro- or monoalkylsilanes and are also referred to as brush
phases. These supports are typically very reproducible from batch to
batch and have good mass transfer characteristics. See polymeric
bonded phase.

multidimensional chromatography Refers to either (1) two or
more columns used in series to produce a separation (e.g., LC and
GC) or (2) a separation that is run in two directions (e.g., TLC).
