OAL Instruments and Equipment

instruments

The OAL, directed by Dr. Andrey Khlystov, is equipped with state-of-the-art instrumentation providing a full range of analytical capabilities for identifying and quantifying trace organic contaminants in environmental matrices. The organic laboratory operations, quality assurance, data management, and validation are integrated into an interactive process that occurs through the field measurement and analytical programs.

Major OAL state-of-the-art analytical equipment includes:
