various column eluates, with or without dilution in carbon dlsulflde,
are then analyzed by GC or GC/MS techniques. Aqueous samples need to
be liquid-liquid extracted with an appropriate solvent (i.e.,
trlchlorotrlfluoroethane) prior to analysis: solid samples would be
extracted with trlchlorotrlfluoroethane using soxhlet extraction or
sonlcation methods (Standard Methods). An allquot of the sample
extract, wlth or without concentration, is then analyzed by CC or
GC/MS . (Sampling and Analysis Considerations for some specific
components in JP-4, i.e., benzene, toluene, xylenes, ethyl benzene and
naphthalene, have been addressed in Volume 1.)
Alternatively, the "oil and grease" content can be measured. This
determination would not be the measurement of an absolute quantity of a
specific component, but rather the quantitative determination of groups
of components with slmilar physical characteristics (i.e., common
solubllity in trlchlorotricluoroethane). The "oil and grease" content
1s defined as any material recovered from extraction With
trlchlorotrlfluoroethane and measured gravimetrically; extraction
methods are those described above for aqueous and soil samples.
A detection limit for JP-4 was not determined; the detection limit
for specific components is expected to be in the range of /rg/L for
aqueous samples and &g for non-aqueous samples.
