AQR Color-Tec® results consistently indicate a relative correlation to split sample laboratory GC/MS (EPA 8260B) comparison data.

This graph shows the relative correlation by plotting AQR Color-Tec readings with the split sample GC/MS concentrations of total CVOHs detected in 61 groundwater samples from a chlorinated solvent site.

AQR Color-Tec® Conversion TableAQR Color-Tec® Conversion Table

Converts AQR Color-Tec® tube readings to µg/L or µg/kg

Based on comparison of Color-Tec data to GC/MS data using over 5000 water samples collected from 152 chlorinated solvent sites.

A “Median” estimated value for each Color-Tec reading was obtained using statistical comparison of Color-Tec data and GC/MS (EPA Method 8260B) data.

The “Range” value reflects the potential deviation from the Median value based on the Color-Tec and EPA Method 8260B comparison results.

The low per-sample cost of AQR Color-Tec® allows for more samples, resulting in increased coverage and reduced uncertainty.

The AQR Color-Tec® data is used to focus definitive analysis sampling onto critical areas.

Combining AQR Color-Tec® with laboratory sampling increases overall data quality at a lower cost by providing improved sampling coverage with high analytical accuracy.
