AN316: Extraction of PCBs from Environmental Samples Using Accelerated Solvent Extraction

Instrument Type: Automated Sample Prep

Accelerated solvent extraction is an extraction method that significantly streamlines sample preparation. PCBs are found in many solid waste materials. This AN describes the application of accelerated solvent extraction to the extraction of PCBs from sewage sludge, river sediments, marine sediments, and oyster tissue. The procedures described in this AN meet the requirements for sample extraction of solid samples as determined by U.S. EPA Method 3545.

LC-MS/MS Analysis of Anti-Infectives In Raw and Treated Sewage

Instrument Type: LCMSMS

“Anti-infectives” is a general term that refers to several classes of biologically active compounds used to treat or prevent infections. Therapeutic agents such as anti - microbials (synthetic) and antibiotics (natural or semi-natural) are examples of anti-infectives. We describe a sensitive and robust method for the determination of some of the most prescribed anti-infectives in trace amounts (lower nanogram-per-liter range) in raw and treated wastewaters.
