This test is used to
determine the presence of gasoline ethers, such as octane
boosters or gasoline oxygenates, that are present in a
sample. Oxygenates typically added to gasoline are MTBE,
ETBE, TAME and DIPE. When released into the environment,
these oxygenates are relatively long-lived. The presence
and relative ratios of these oxygenates can provide
information about the time and origin of manufacture of the
gasoline. In order to make this possible, product
specifications must be obtained from manufacturers of
gasoline supplying the impacted area.
In addition, the leaded
gasoline additives ethylene dibromide and ethylene
dichloride can also be measured. The presence of these
compounds indicates impact from leaded gasoline. The
results for this analysis are reported as a list of the
numerical concentration of these particular analytes.
