The cost-benefit analysis of performing TOC testing reveals significant benefits, including:
EPA Method 415 TOC testing involves the following steps:
1. Sample preparation: Collection, storage, and preparation of samples for analysis
2. Measurement: High-temperature oxidation and non-dispersive infrared detection (NDIR) are used to measure TOC content
3. Calibration and validation: Regular calibration and validation procedures ensure accurate results
Calibration and Validation Procedures
Accurate TOC measurements require:
Measurement Methods
Two common measurement methods are used in TOC testing:
1. High-temperature oxidation: A high-temperature oxidizer is used to convert organic carbon into CO2, which is then measured by NDIR
2. Non-dispersive infrared detection: A sensor detects the absorption of IR radiation by CO2, indicating the presence and quantity of organic carbon
Test Equipment
Accurate TOC measurements require:
Data Analysis and Reporting
Results are analyzed and reported in accordance with standard operating procedures (SOPs) and regulatory requirements.
