Applications
Harmon reviewed the many different types of gels that are
available to the chromatographer, and reported that the relative-
ly soft gels, such as the lower Bio-Beads (particularly S-X1 )
products swell appreciably in many solvents.

Remarkable sep-
arations can therefore be achieved at low flow rates.
Many different types of compounds have been separated on
Bio-Beads S-X beads. The beads have been used for analysis
and quantification of pesticides
2-5
and rodenticides.

Bio-
Beads S-X beads are the basis of the official EPA procedure for
the measurement of organic priority pollutants in sludge.

The
beads are useful for separation of polycyclic aromatic com-
pounds,
9-11
assessment of tissue reaction to biomaterial,
12, 13
and
fractionation of halogenated environmental contaminants.
14-17
Other applications include separation of tall oil components,
18
lipids,
19, 20
alkalines,
21
fatty acids,
22
a variety of hydrocarbons,
23
and polystyrenes.
24
These beads can also be used to determine
polymer molecular weights and molecular weight distribu-
tions.
24-28
They have been used for the separation of low molec-
ular weight trimethylsilylated silicic acid,
29
and for the isolation
of low molecular weight polar organics in fatty tissues for sub-
sequent GLC-MA analysis.
