AN1081: Automated Solid-Phase Extraction of Triclosan in Tap Water Using Hydrophilic Reversed-Phase Cartridges and HPLC with UV Detection

Instrument Type: HPLC

In this application note, triclosan-contaminated samples of tap water were simulated by adding known amounts of triclosan-containing liquid hand soap to Sunnyvale tap water. The Dionex AutoTrace 280 instrument along with the high-surface-area, hydrophilic, reversed-phase cartridges were used to concentrate triclosan. The contents of the cartridge eluent were then separated on a reversed phase column using HPLC with UV detection.

AN1086: Automated Solid Phase Extraction of 14 Explosives in Tap Water Based on U.S. EPA Method 8330 Using Hydrophilic Reversed-Phase Cartridge

Instrument Type: HPLC

The U.S. EPA Method 8330, first introduced in November 1990, is the most common method for the analysis of explosives. Analytes can be detected down to 2.5 ppb in water, soil, or sediment. Used here are the Thermo Scientific Dionex AutoTrace 280 Solid-Phase Extraction (SPE) instrument and the Thermo Scientific Dionex SolEx SPE HRPHS cartridge to concentrate the explosive residues, followed by HPLC.

TN148: Automated Extraction and Determination of Human Hormones in Drinking Water Using Solid-Phase Extraction and HPLC with UV Detection

Instrument Type: HPLC

This Technical Note describes the use of high-surface-area solid phase extraction (SPE) to extract seven human hormones from drinking water using the Dionex AutoTrace 280 SPE instrument. Extracts were subsequently quantified using high-performance liquid chromatography (HPLC) to determine the recovery.
