Additionally, there is an Application Modification section that highlights the use of the Biotage® Horizon 4790 and Biotage® VacMaster™ Disk for this application.

In this application note, Biotage outlines an automated extraction method utilizing the Atlantic® HLB-M SPE Disk and Biotage automated and manual SPE solutions for the extraction of pharmaceuticals in water. The first section highlights the use of the Biotage® Horizon 5000 fully automated extraction system and the method used for this application. Additionally, there is an Application Modification section that highlights the use of the Biotage® Horizon 4790 (with data and discussion) and Biotage® VacMaster™ Disk for this application.

In this application note, Biotage outlines an automated extraction method utilizing the Atlantic® HLB SPE Disk and the Biotage automated and manual SPE solutions for the extraction of hormones in drinking water. The first section highlights the use of the Biotage® Horizon 5000 fully automated extraction system and the method used for this application. Additionally, there is an Application Modification section that will highlight the use of the Biotage® Horizon 4790 (with data and discussion) and Biotage® VacMaster™ Disk for this application.

In this application note, Biotage describes the use of the SPE-DEX® 5000, a system for automation of disk solid phase extraction (SPE). Three different disk media types are evaluated to better understand the performance of each for a wide range of polycyclic aromatic hydrocarbons (PAH) compounds.

For more than 25 years now, the US has been testing for organic compounds in drinking water using US EPA Method 525. The most common version of this method, Method 525, is a diverse method with more than 100 compounds listed in a wide range of chemical groups such as pesticides, polychlorinated biphenyls, and polyaromatic hydrocarbons. Method 525 offers other changes to the method that may also be of use in making the method more rugged. Additional compounds are evaluated and may be added to the method as the regulatory list is amended every few years.

This application note demonstrates the performance of automated SPE for the extraction of PAHs from surface water sampled from a nearby pond containing some particulate. An automated system with DVB disks, following the requirements of method EN 16691 was used.

This application note describes the use and performance of the Horizon Technology SPE-DEX® 4790 automated extractor system, with the Atlantic® DVB SPE disk for the extraction of water samples.

Triphenyl phosphate is used as a plasticizer and flame retardant. It is found in foam and televisions as a flame retardant, in candy wrappers, nail polish and other consumer products. It has come into more common use as a safe alternative to polydibrominated ether (PDBE) compounds which were good flame retardants, but found to be a health hazard and have been phased out in many materials. Triphenyl phosphate has become a chemical of concern in several countries. In the US there are airborne exposure limits developed by OSHA. Although triphenyl phosphate is not on the California prop list, which would require listing in public places, there is concern that human exposure may be significant. Recent studies have also indicated concern about possible endocrine disruptor capability. A recent study found that triphenyl phosphate can be absorbed into the body from nail polish. The study found that levels of a metabolite, diphenyl phosphate were elevated seven fold in urine several hours after the nail polish was applied.

This application note presents the data collected as part of the demonstration of disk solid phase extraction validation for US EPA method 625.1. Nine different wastewater matrices were evaluated and tested against the criteria listed in Table 6 of method 625.1. The analytes chosen for evaluation were from Tables 1 and 2 in method 625.1, with a few extra analytes from Table 3. The analytes from Table 3 are omitted in this note because there was no acceptance criteria for comparison.

Solid phase extraction (SPE) is a method of sample preparation that separates and concentrates analytes from solution prior to analysis. In this video find out more about how SPE works, comparing SPE to liquid liquid extraction (LLE).

This video demonstrates the 4790 extractor and how dirty samples are handled for automated sample preparation in analytical testing labs. It highlights the use of discs to remove particulates by combining 47mm, 1 micron and 90mm, 5 micron discs in a novel holder.
