Determining
Diesel and Oil Range Organics In Sea Water Using Automated
SPE
Although
not frequently a problem, recent incidents at sea have led
to large amounts of crude oil being released and dispersed
throughout the Gulf of Mexico. Originally presumed to be
Louisiana Sweet Crude, sample testing later revealed a harsher
form of crude containing a high amount of asphaltenes was
actually being released. The differences are substantial,
as Louisiana Sweet degrades more readily in nature than
crude oil containing asphaltenes. While data is still mixed
as to what type of oil is being released, the need for a
fast and reliable method of testing still exists within
the environmental industry of the Gulf Coast states.
Traditional
techniques used for the extraction of 8015B samples, such
as liquid-liquid extraction (LLE), can be problematic. Errors
may occur, as the efficient and accurate use of these chemicals
is reliant on factors such as the amount of oil in the water
and droplet size, which are not always known. As an alternative
procedure, the use of automated solid phase extraction (SPE)
simplifies and reduces the amount of analyst interaction
with a given sample. Due to the nature of SPE, emulsions
cannot form and the amount of solvent needed for a given
extraction is a fraction of traditional techniques.
This
Application Note will highlight the use of the Horizon Technology
SPE-DEX® 4790 Automated Extraction Systems. This fully automated
extraction system makes use of SPE technology to reduce
costs associated with the extraction procedure and to increase
the throughput of a laboratory. It is designed to extract
a wide range of target analytes from both influent and effluent
sample matrices and can handle a high amount of suspended
solids.
The
use of the automated systems from Horizon Technology should
allow for a laboratory to realize significant decreases
in the areas of labor, time per sample, and cost of analysis
while maintaining the high levels of precision and accuracy.
These qualities are especially desired in the time of an
environmental tragedy like the one experienced in the Gulf
of Mexico.
