NEW
Atlantic™ HLB SPE Disks for EPA Method 8270 and EPA
Method 1694
The
NEW Atlantic™
HLB SPE Disk, is a solid-phase sample preparation product
for the analysis of EPA Method 8270 (semi-volatile
organics), EPA Method 1694 (pharmaceuticals and personal
care products), endocrine disruptors, and other emerging
contaminants in wastewater and drinking water.
The single-use Atlantic™ HLB SPE Disks are designed to economically
handle samples at higher rates of speed than ordinary cartridges
leading to greater laboratory productivity. The HLB sorbent
is a Hydrophilic-Lipophilic-Balanced, water-wettable, reversed-phase
sorbent. It is made from a specific ratio of two monomers,
hydrophilic N-vinylpyrrolidone and lipophilic divinylbenzene,
providing reversed-phase capacity with a neutral polar ‘hook’
for enhanced retention of polar anayltes.
Available in three capacities High (H), Medium (M), Low
(L).
The Atlantic™ HLB SPE Disk has an improved format which
enables greater efficiency, reliability, and reproducible
results.
One of the improvements of the Atlantic™ HLB SPE Disk formulation
is reduced glass fiber content, which decreases the amount
of residual water retained during extraction. The reduction
in glass fiber provides more efficient extractions when
dealing with non-polar solvents. For water miscible extractions,
the reduced glass fiber means less water in the extract
and faster evaporation times when concentrating the sample.
Atlantic™
HLB SPE Disk Features:
- Reduced
glass fiber content
- Reduced
water retention content
- Improved evaporation times for EPA Method
1694
- Improved precision of results for EPA Method
8270
- No
compromise on the disks built-in pre-filtering capability
- Available
in three capacities High (H), Medium (M), Low (L)
The
Atlantic™ HLB SPE disks are built on the Horizon Technology
Atlantic™ Disk platform, widely used by environmental laboratories
analyzing samples with gas and GC, GC-MS, LC, and LC-MS,
in compliance with approved methods of analysis. The Atlantic™
HLB SPE Disk is specifically designed and ‘Certified for
Automation’ with the SPE-DEX® 4790 Automated Extractor System
also developed by Horizon Technology.

Method
Detection Limits for EPA Method 8015 Diesel Range Organics
Using Fully Automated Extraction and Concentration Equipment
One of the most frequently desired quantities in environmental
chemistry is the amount of diesel range organics (DROs)
contained within a sample. The analysis of DROs is performed
in almost every major environmental laboratory under the
EPA Method 8015. This method is commonly used to determine
the contamination of alkanes from C10 to C28 caused by leaky
underground storage containers. In addition to testing under
Method 8015, many state-run environmental agencies have
used
Method 8015 as the foundation for their own, more in depth,
methods; for example, the Massachusetts VPH and EPH methods
and the Florida TRPH method.

Determination
of Micocystins in
Water Using Automated Solid Phase Extraction and Concentration
Techniques
At present,
pollution of freshwater algae has become a global environmental
problem. Of all the different pollution types, microcystin-LR
is the most toxic and the most acute hazard as far as is
known presently. There have been many serious accidents
that are caused by pollution of freshwater algae all over
the world. The microcystin-LR maximum contaminant level
(MCL) in drinking water recommended by the World Health
Organization (WHO) is 1.0 ug/L.

Determination
of Trace Phthalate Ester Compounds for EPA Method
8061A
The purpose of this application note is to demonstrate the
capabilities of the automated Horizon Technology solution
when used for the analysis of EPA method 8061A phthalate
ester compounds in surface and ground water. Method 8061A
states gas chromatography/mass spectrometry (GC/MS) can
be used as an
alternative for compound confirmation for
phthalate esters.

Determination
of Trace Phthalate Ester Compounds in Ground and Surface
Water for Global Applications
The purpose of this application note is to demonstrate the
capabilities of the Horizon Technology’s complete automated
solution when used for the analysis of phthalate ester compounds
in surface/ground water. Phthalate esters are mainly added
to plastics to improve characteristics such as flexibility,
durability, transparency, or longevity of life. However,
due
to the lack of a covalent bond between the phthalate esters
and the plastics they are
mixed with, the phthalate esters are easily
released. Studies have found that exposure to certain types
of these phthalates can lead to detrimental health effects
such as endocrine disruption or birth defects.

DID
YOU KNOW?
You
Should Rebuild Your Water Inlet Valves Every
Six Months
Over
time, water inlet valves on both the Horizon Technology
SPE-DEX 1000XL and 3000XL Extractors become dirty. Some
parts such as the solvent rods and O-ring can become brittle,
causing the valve to become difficult to open - putting
added stress on your extractor.
For these reasons, it is important to rebuild rebuild your
valves at least once every six months. Rebuilding the valves
is a straight forward process that can be done in about
15 minutes, with few tools and parts.
