Development of an Improved Confirmation Separation Suitable for Use with SW846 Method 8330.

摘要

An improved RP-HPLC confirmation separation was developed that is suitable for use with EPA SW846 Method 8330. This separation provides adequate resolution of the analytes most commonly found in explosives-contaminated waters and soils. The separation is achieved on an LC-CN (cyanopropyl) column eluted with an eluent composed of water (65%), methanol (I 2%) and acetonitrile (23%) at 1.2 mL/min. Analysis of field-contaminated soil and groundwater samples indicate that this confirmation separation is an improvement over the confirmation separation currently recommended in SW846 Method 8330.
