Officials from the Environmental Protection Agency presented a $167,874 check to the LSU AgCenter on Jan. 8 as part of an integrated pest management program.

New challenges are what make working at this lab fun

This Application Note will demonstrate the extraction of 1,4-Dioxane from an aqueous matrix using Option 1 of EPA Method 522 for 500 mL initial volume sample. It will make use of the SmartPrep Cartridge Extraction System to produce a valid Initial Demonstration of Precision (IDP) and Initial Demonstration of Accuracy (IDA).

Dionex Application Notes 817 and 818 describe using automated solid-phase extraction (SPE) versus liquid-liquid extraction (LLE) for the determination of oil and grease from liquid (typically water) samples to meet the requirements of EPA Method 1664.

Laboratories frequently accumulate bottles of old chemicals, often toxic or hazardous, that are no longer used. Laboratory managers can use several strategies to properly reuse or dispose of these chemicals.
