This application note demonstrates the use of automated solid phase extraction for a variety of pharmaceutical compounds in drinking water,
wastewater and surface water. The criteria specified in US EPA Method 1694 was met, even at very low concentrations. For lower concentrations a larger sample of water may be processed.

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.

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.

Method 508.1 is used to determine twenty-nine chlorinated
pesticides, three herbicides, and four organohalides in
ground water, drinking water, and water in any treatment
stage. The analytes are extracted from the water using a 47
mm C18 disk. The disk is extracted on the Horizon
Technology SPE-DEX® 4790 Automated Extraction
System using Ethyl Acetate and Methylene Chloride
(DCM). The extract is then dried and concentrated using
the Horizon Technology DryVap® with DryDisk®
technology. Final analysis is by GC/ECD.

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.

EPA Method 8141B describes the performance based procedure to determine low ppb levels of organophosphorous pesticides in ground water.
The OP pesticides are extracted using solid phase extraction (SPE) based on the procedure outlined in Method 3535A for OP pesticides by Method 8141. The analysis is performed with capillary GC using a FPD
(flame photometric detector). This initial demonstration of capability was conducted using the Biotage® Horizon 4790 Automated Extractor System.

The chemical 1,4-dioxane is primarily used as an industrial solvent or solvent stabilizer. Its carcinogenic classification by US EPA in Group B2 and by the state of California in Proposition 65 (safe harbor limit of 30 μg/day) along with its more recent detection in multiple groundwater supplies across the US have led to its placement on the UCMR 3 list to evaluate its occurrence in
drinking water supplies. This has increased demand for testing.
