SPE-DEX® 3000XL Automated Extractor System
The SPE-DEX® 3000XL Oil and Grease Machine
has undoubtedly increased the capacity of the
lab, and therefore improved the profitability
of this analysis.
With its easy-to-use automated programs, the amount
of labor needed for each sample is greatly reduced,
and since the extraction steps are automated,
batch consistency is easily maintained between
analysts since the SPE-DEX® 3000XL has excellent
accuracy and precision.
Recently, we also purchased a new controller for
the SPE-DEX® 3000XL which helped us meet new
EPA guidelines and with Horizon Technology's technical
assistance we were able to successfully update
the system to incorporate these changes to be
compliant with the intent of the EPA methodology.
The on-site service the technical team provided
was outstanding, and critical in overcoming ambient
conditions, that had a negative impact on the
results generated from the system.
The SPE-DEX® 3000XL ease-of-use, reproducibility,
and reliability, coupled with Horizon Technology's
technical support and expertise, make this system
the ideal choice for this application.
I look forward to new products as they emerge
from Horizon Technology.

Method 1664A: Recently, the EPA mandated changes
in the automated process for reporting results
in order to be in compliance. We received our
new Horizon Technology SPE-DEX® 3000XL Controller
- installing it was a breeze!
In accordance with the reproduction in the new
methodology created by Horizon Technology, we
used their 47mm disc holder and Pacific Premium
SPE disks. We have had great success with our
returns, receiving an average of 95% recoveries.
The SPE-DEX® 3000XL Automated Extraction System
is a very dependable instrument, and we were extremely
pleased with the quality of the new Pacific Premium
SPE disks.

 We
used to perform rainwater outfalls (EPA 1664 Oil
& Grease) by
hand at about 4 - 6 samples a day. Now not
only do we do that - and the matrix blanks - in
half that time, but the recoveries are better
too.

 The
transition from the SPE-DEX® 4750 to the 3000XL
made it easier for me to analyze both clean and
dirty samples. I have been able to analyze samples
with much more expedience and confidence in the
results.
As expansion is predicted in the future, I would
surely invest in another 3000XL.

 After
reviewing the data, the results were excellent.
There were
five method blanks that were analyzed, and four
of the results were less
than 1 mg/L and one was 1.6 mg/L. These values
are well less than the laboratory reporting limit
of 5 mg/L.
There were also five laboratory control samples
that were spiked at 40 mg/L. The results ranged
from
86-98%; the method acceptance limit is 78-114%
- again, the results were excellent.
