On-Site Low Levels TPH Screening Device in Water and Soil • Tsan-Liang Su, Ph. D. • Stevens Institute of Technology • Hoboken, New Jersey, USA • Questor Research Proposal Presentations • November 16, 2010
On-Site Low Levels TPH Screening Device in Water and Soil CHALLENGE APPROACH Sensor Probe/ Device Development Raman Spectrometry probe associated with a potable Raman Spectrometer Data Analysis Model Development Analytical methods and procedures development TPH identification and concentration calibration in soil and water • Eliminated or reduced laboratory-based TPH analysis • Turn around time • Cost too high • Current technology • Field Analytical Methods (FAMs) • Ultraviolet fluorescence spectroscopy • Infrared analysis
Business Benefits Costs Saving $2 per sample analysis vs. $30 per IR Analysis & $50 per GC Analysis On-site and Real-time Analysis Reusable sensor probes for integration with optical sensor network Better detection limit: 0.1 mg/L vs. 1 mg/L Multiple contaminated compounds identification capability
