- Data Defensibility with Vapor Intrusion Considerations. As the environmental industry moves to lower and lower reporting limits, data defensibility becomes a topic of utmost importance. Current methodology for GC/MS analysis of volatile organic compounds, i.e. TO-15, supports ppbv level analysis. However risk assessment requirements and recent EPA and multiple state department documents are driving reporting limits into the pptv range. This seminar will discuss the issues associated with maintaining data defensibility at these lower reporting limits, as well as, discuss several basic components of data defensibility for all environmental air samples.
- Introduction to Sample Media for Air Analysis. Review the types of media used in air sampling. Procedures for preparing media will be discussed. The multiple certifications available for media and their importance to project DQOs will be reviewed. The proper use of Summa canisters will be discussed, including how to assemble and test the sampling train when taking either a grab or integrated sample. Understanding vacuum, flow controller function, and environmental factors will be discussed. Sample manifold considerations will be highlighted. You will also learn the best way to take a sample duplicate or split, and the important parameters to monitor when collecting a vapor sample and how to trouble shoot in the field. Discussion of the differences between passive and.
- VOCs and Semi-VOCs using Thermal Desorption Tubes and TO-17. Discussion of the various applications of this approach for soil gas, indoor and ambient air samples. Comprehensive data with extremely low detection limits achievable. Excellent for fuel-impacted and chlorinated sites. Active and passive sampling trains available.
- Method-Specific Seminar Topics. Air Toxics can also customize a seminar for your office, and include discussions on any of the following specific topics:
- LEED - Green Building Certification
- Volatile Organic Compounds (VOCs) by VOST and TO-17
- High Level VOCs by TO-15
- Low Level VOC Analysis by GC/MS SIM
- Landfill Analyses: Methods TO-15, ASTM D-1945/6 and Siloxanes
- Semi-Volatile Organic Compounds (SVOCs) by TO-13 and 8270C
- Carbonyls using DNPH (multiple methods)
- Sulfur Compounds by ASTM D-5504
- Atmospheric Analyses
- TO-3 and TO-12
