Extracting Oil and Grease from Aqueous Samples
H
orizon Technology’s SPE-DEX®
3000XL extractor provides an
alternative to expensive, labour-intensive liquid-liquid extraction (LLE)
methods for extracting oil and grease
from aqueous samples. Using a combination of advanced liquid handling and
‘Certified for Automation’ Pacific O&G
SPE disks, the SPE-DEX 3000XL
delivers the accuracy and consistency data
laboratories need to comply with Method
1664A and 1664B QC specifications.
The SPE-DEX 3000XL extractor is

a three-station system,
and is automated
allowing unattended operation. It processes
samples directly
from the original
sample bottle.
It automatically
delivers all solvents, regulates
sample processing and disk drying
times, rinses the sample bottle
and collects the extract. The
3000XL extractor is capable
of handling any combination
of 47, 50 and 100mm disks.
The sample inlet valve allows
for the most challenging
samples to be processed.
The extractor can be used
with the Solvent Trap™
Recovery system, which
captures up to 70% of the
n-hexane solvent
vapour from EPA Method 1664A oil and
grease extractions. It can also be used
with the Speed-Vap™ III Solvent Evaporation system, which provides safe and
fast evaporation of n-hexane solvent. ⚛
