Horizon Technology (a part of Biotage) is the leader in disk SPE technology. Atlantic® SPE Disks are the only Certified for Automation disks available on the market today.
Semivolatile organic compounds (SVOC) have a variety of chemical properties that have been found to cause harmful effects to both humans and the environment. Accurate measurements are challenging to obtain because SVOCs readily adsorb onto surfaces, and are found in common household items such as cleaning agents, personal care products, electrical components, pesticides, water and food.

The US EPA monitors a variety of chemicals in water that may cause harm to humans or wildlife in order to minimize exposure. Method 625 was developed by the Office of Science and Technology in the Clean Water program to monitor a large suite of semivolatile chemicals in wastewater for compliance with the National Pollution Discharge Elimination System (NPDES). NPDES is a system of permitting that regulates the characteristics of water that is released into a waterway, defined by industrial category. The permitting levels are set depending on the waterway’s use.

Environmental methods for water analysis often specify sampling 1 L of water to provide the sensitivity needed for determination of contaminants at low concentrations for health monitoring. In the past decade sensitivity of the analytical technique (GC/MS) has improved and with split/splitless introduction and large volume injection options a wide range of concentrations can be effectively measured.

Polycyclic aromatic hydrocarbons (PAHs) can be found in a number of water types, such as drinking water, surface water, ground water and wastewater. There are serval types of extraction techniques that can be implemented to remove them from water for measurement including liquid-liquid extraction (LLE), continuous liquid-liquid extraction (CLLE) and solid phase extraction (SPE). With LLE and CLLE there is little selectivity within the methods for difficult matrices or other compound interferences.

Dioxins are of great environmental concern due to their teratogenic, mutagenic, and carcinogenic impact. These lipophilic compounds bioaccumulate in humans and wildlife and can have half lives of up to 132 years, making them persistent organic pollutants (POPs). Traditional SPE requires a filtration step to remove particulates when using SPE cartridges, because of clogging issues.

Drinking water is a critical resource important for human health. As water becomes more scarce, quality will become increasingly important and monitoring will be required more frequently and at lower concentration levels. The number of compounds and lower concentrations for monitoring will make extraction and analysis even more challenging.

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental contaminants, naturally occurring in coal, crude oil, gasoline, and their byproducts (e.g. coal tar or creosote). In addition, PAHs are formed in the incomplete combustion processes of all organic materials, such as wood or fossil fuels. Consequently, the EU water framework directive (WFD) lists in its annex X the whole group of PAHs as priority hazardous substances.

EPA Method 506 is used to determine Phthalate and Adipate Esters in drinking water. The analytes are extracted from water using a Horizon Technology 47 mm Atlantic C18 disk. The disk is extracted with Acetonitrile and Methylene Chloride. The extract is then dried and concentrated to a final volume of 1.0 mL using the Horizon Technology DryVap® with DryDisk® technology. Final analysis is by GC/PID.

Product Notes
US EPA method 625 is used to determine acidic, basic, and neutral semi-volatile organic compounds (SVOC) in municipal and industrial wastewater. Revision A of this method is applied to a total possible list of 364 compounds that include; polynuclear aromatic hydrocarbons, chlorinated hydrocarbons, pesticides, phthalate esters, organophosphate esters, nitrosamines, haloethers, aldehydes, ethers, ketones, anilines, pyridines, quinolones, aromatic nitro compounds, and phenols.

Product Notes
One of the recent introductions is a system to extract a full range of acid/base neutral compounds from various types of water samples using a One-Pass system. In this case, rather than extract water at pH 2, adjust the pH of the water to 12 and re-extract, the water is passed once through a multi-media SPE disk and then a carbon cartridge before being delivered to waste. The elegance of this approach is the elimination of the basification step, which requires additional labor adjusting the pH and time passing the sample through the disk a second time after the first elution of acids and neutrals. The additional benefit of omitting the basification step eliminates the formation of insoluble metal hydroxides that can restrict the flow of sample through the disk or add significant time if a liquid-liquid extraction is used.

Within each disk holder there is a support screen. The disk holders that we will cover are used with a broad range of Horizon products. The placement and condition of the support screen is critical to the functioning of these products.

Horizon Technology “Certified for Automation”, Atlantic® SPE Disks are QC-tested in our lab to guarantee that you receive the highest quality results when used in conjunction with the Biotage® Horizon 5000 system. See the SPE Disk Guide for a more detailed description matching disk-types and the compounds for which they may be used.
The Atlantic High Capacity C18 SPE Disk provides added retention per disk for improved recovery of compounds that have weaker interactions with C18 media. Much like the original Atlantic C18 disk, the new Atlantic High Capacity uses end-capped C18 to eliminate unpredictable secondary interactions with unreacted silanols. The disk can be used for drinking water applications such as EPA Method 525.2
Users have experienced higher recoveries for compounds such as dimethoate, 2,6-DNT, and 2,4-DNT. In the specific case of caffeine, a compound used as a drinking water tracer, recoveries more than doubled over standard C18 disks.
This disk contains media with 3 analyte retention mechanisms that significantly simplify the extraction process with the benefit of reduced labor, faster extraction times and elimination of high pH precipitates. This new multi-mode disk chemistry enables the retention of over 100 target semi-volatile compounds with a sample pH of 2. Now acidic, neutral and basic analytes can be retained in a single water extraction step using this 47 mm disk. For extremely hydrophilic compounds, the optional Horizon Carbon Cartridge is placed after the One Pass disk to scavenge the sample effluent for light-end semi-volatile organics (LSVO). In this configuration all classes of compounds from EPA Method 8270/625 are automatically captured, eluted off the media and ready for drying and concentration.
This silica based C18 is end-capped to eliminate unpredictable secondary interactions with unreacted silanols. This reversed-phase media can be used for EPA Method 525.2 along with other drinking and wastewater methods.
The DVB (divinylbenzene) polymer is a pH independent reversed-phase media that is listed for use in the EPA drinking water method for a full suite of analytes, EPA Method 525.3.
The polymeric HLB (hydrophilic/Lipophilic Balanced) media in this disk comes in low, medium and high capacity formulations. These disks can be used for drinking and wastewater applications. Common applications include semi-volatile organic analysis and EPA Method 1694 (pharmaceuticals and personal care products), endocrine disruptors, and other emerging contaminants in wastewater and drinking water.
For use with the Atlantic SPE Disk, the Atlantic Prefilter increases sample flow rate without compromising recoveries. Perfect for dirty samples with lots of particulates, the Atlantic prefilter will accelerate sample throughput, and enables reproducible recoveries. These prefilters are “Certified for Automation” designed specifically for use with the Biotage® Horizon 5000 system.
These prefilters have proven to be effective in handling highly particulate laden aqueous samples. They are specifically designed and certified for use with the EZ Flow Disk Holder on the Biotage® Horizon 5000 system and are available in a 1 micron and 5 micron size.
