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:

Analysis of complex samples can be difficult due to spectral overlap of different luminescent compounds.
Limited field applications.

ASTM Standards/EPA Methods:

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