6 SAMPLE ANALYSIS TOOLS for VOCs, SVOCS, and PESTICIDES

6.2 EX-SITU ANALYSIS

6.2.26 Room-Temperature Phosphorimetry


Use: Analyzing halogenated SVOCs, PAHs, pesticides and herbicides, and PCBs.

Description:

Room-temperature phosphorimetry is based on detecting the phosphorescence emitted from organic compounds absorbed on solid substrates at ambient temperatures (conventional phosphorimetry requires cryogenic (low temperature) equipment). Instrument design is similar to fluorescence techniques (see 6.2.12 and 6.2.13).

Analytes:

4. Halogenated SVOCs
5. PAHs
6. Pesticides/Herbicides
12. PCBs

Media:

Soil/Sediment Water Gas/Air
ADEQUATE BETTER ADEQUATE
Selectivity: Technique measures the specific contaminant directly.
Susceptibility to Interference: High.
Detection Limits : 100-1000 ppb (soil); 1-50 ppb (water).
Turnaround Time per Sample: Hours.
Applicable To:
Screen/Identify Characterize Concentration/Extent Cleanup Performance Long-Term Monitoring
BETTER ADEQUATE BETTER BETTER
Quantitative Data Capability: Data become quantitative with additional effort.
Technology Status: Commercially available technology with limited field experience.
Certification/Verification: Technology has not participated in CalEPA certification and/or CSCT verification program.
Relative Cost per Analysis: Mid-range expense.

Limitations:

ASTM Standards/EPA Methods:

No applicable ASTM standards or EPA methods are cited for this technology.
