EPA Method 8081B
Automated Solid Phase Extraction of Organochlorine Pesticides from Water Using Certified for Automation Atlantic SPE Disks

Solid Phase Extraction (SPE) is an increasingly popular method to analyze trace contaminants in water samples. Benefits of the technique include less solvent usage and exposure, less time, and less effort than liquid-liquid extraction.

In a recent Horizon Technology study, the effectiveness of the Atlantic SPE Disk in extracting organochlorine pesticides (EPA Method 8081B) from water samples was investigated, and an optimized method of extraction developed.

Pesticide pollution is a subject of global concern and although many countries have now banned the use of organochlorine pesticides, they linger in the environment and can contaminate water sources. Organochlorine pesticides can be toxic to animals and humans, so methods which accurately and easily quantify them are essential.

The results of the study demonstrated that the Atlantic Disk is able to quantify a wide array of organochlorine compounds in a single extraction; each at a higher recovery rate than the standard set by the EPA. The success in analyzing a range of 20 organochlorine pesticides illustrates the breadth of pesticides the Atlantic Disk is able to accurately quantify.

Did you know that Horizon Technology offers Service Agreements?

A Horizon Technology Service Agreement is the best way to protect your investment.

A great example of this is customers who take advantage of our Depot Service Agreements. With the Depot Service Agreement, loaner instruments are shipped when needed. Once the loaner is received, the instrument in need of repair or yearly preventative maintenance is shipped to headquarters.
