Atlantic® SPE Disks

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.

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.

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.
