AN328: Extraction of Explosives from Soils by Accelerated Solvent Extraction (ASE)

Instrument Type: Automated Sample Prep

Compounds used in high explosives may be toxic, carcinogenic, and are found on the Resource Conservation and Recovery Act (RCRA) list. These compounds and their metabolites are monitored in soils and ground waters to ensure compliance with U.S. EPA regulations. This application note reports on the use of ASE for the extraction of explosive compounds such as HMX, RDX, 2,4,6-trinitrotoluene (TNT), and some of their known metabolites from soils.

AN322: Selective Extraction of PCBs from Fish Tissue Using Accelerated Solvent Extraction

Instrument Type: Automated Sample Prep

The analysis of extracts containing polychlorinated biphenyl (PCB) contaminants from fish tissue and fish homogenates can be hindered by the presence of coextracted fatty materials. Here demonstrates that selective extractions can be performed using accelerated solvent extraction with the proper choice of solvent and sorbent in the extraction cell. Results are given for the recovery of PCBs from contaminated fish tissue showing that extracts do not require further cleanup prior to analysis by gas chromatography when using accelerated solvent extraction.

AN354: Accelerated Solvent Extraction of Extractables from Polymeric Components Used in Precision Drug Delivery Devices

Instrument Type: GCMS

Many regulatory authorities require the routine monitoring of extractables from polymeric drug delivery device components. This Application Note outlines the use of accelerated solvent extraction in the routine extractables analysis of a typical elastomeric device component.
