EPA Method 8275D GC/MS Semivolatile Organics Laboratory Testing Service: A Comprehensive Guide
The EPA Method 8275D GC/MS Semivolatile Organics testing service is governed by a suite of international and national standards that ensure the accuracy, precision, and reliability of the results. The key standards that apply to this specific laboratory test are:
1. EPA Method 8275D: This is the primary standard for the determination of semivolatile organic compounds (SVOCs) in environmental samples using gas chromatography-mass spectrometry (GC/MS).
2. ISO 17025:2017: This standard specifies the general requirements for the competence of testing and calibration laboratories.
3. ASTM D5290-19: This standard describes the test method for determining the total mass concentration of semivolatile organic compounds in water, soil, and solid waste using GC/MS.
4. EN 13965:2015: This European standard specifies the requirements for the analysis of semivolatile organic compounds in environmental samples using GC/MS.
The legal and regulatory framework surrounding this testing service is governed by various national and international regulations, including:
1. US Environmental Protection Agency (EPA) regulations: The EPA regulates the determination of SVOCs in environmental samples under the Clean Air Act, Clean Water Act, and Resource Conservation and Recovery Act.
2. European Union (EU) regulations: The EU has implemented the Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) regulation, which requires the analysis of SVOCs in environmental samples.
3. International Council on Clean Transportation (ICCT): The ICCT promotes the adoption of international standards for the analysis of SVOCs.
The standard development organizations responsible for developing and updating these standards include:
1. American Society for Testing and Materials (ASTM)
2. International Organization for Standardization (ISO)
3. European Committee for Standardization (CEN)
These standards are constantly evolving to reflect new analytical techniques, methodologies, and technologies. The update cycle typically occurs every 5-10 years.

3. Concentration: Extracted and cleaned-up compounds are concentrated to facilitate analysis.
Instrumental Analysis
The GC/MS instrument is used to separate, identify, and quantify SVOCs in environmental samples. This involves:
1. Separation: Compounds are separated based on their boiling points and affinity for the stationary phase.
2. Identification: Mass spectrometry (MS) is used to identify compounds based on their molecular weight and fragmentation patterns.
3. Quantification: Quantitative analysis is performed using internal or external calibration standards.
Reporting
The final report includes:
1. Results: Concentrations of SVOCs in the sample matrix are reported.
2. Method detection limits (MDLs): MDLs for each compound are provided to ensure transparency and accuracy.
3. Quality control data: QC data, including blanks and spiked samples, are included to demonstrate laboratory competence.
Reporting Requirements
The report must include:
1. Sample identification
2. Analysis conditions
3. Results
4. Method validation information
5. Certifications of analysis
