Semi-volatile Organic Compound (SVOC) Testing: Comprehensive Analysis with SIM Technology

Protecting Our Environment with Accurate and Reliable SVOC Analysis

Semi-volatile Organic Compounds (SVOCs) are a broad class of organic chemicals that can pose significant risks to human health and the environment. Accurate and reliable testing is crucial for identifying and quantifying these compounds in various environmental matrices, ensuring compliance with regulations and protecting our natural resources.

Teklab offers comprehensive analytical testing for SVOCs using industry-standard methods, including SW-846 8270, SW-846 8270 SIM (Selective Ion Monitoring), and EPA 625/625.1. Our experienced team and state-of-the-art instrumentation provide accurate and defensible data for a wide range of applications.

What are Semi-volatile Organic Compounds (SVOCs)?

SVOCs are organic chemicals that have a relatively low vapor pressure, meaning they tend to evaporate more slowly than volatile organic compounds (VOCs). This characteristic allows them to persist in the environment for longer periods, potentially contaminating soil, water, and air. SVOCs can originate from various sources, including industrial processes, pesticides, petroleum products, and combustion byproducts.

🧪Our semi-volatile organic testing lab routinely analyzes:

• Soils: Assessing soil contamination from industrial spills, agricultural runoff, and other sources.
• Waters: Monitoring surface water, groundwater, and wastewater for SVOC contamination.
• Special Wastes: Characterizing hazardous wastes and ensuring proper disposal.\

Whether you require analysis for single compounds or complex mixtures, Teklab has the expertise and resources to meet your needs. We are the trusted environmental laboratory that will meet and exceed your SVOC, BNA (Base/Neutral/Acid extractables), and SIMS testing expectations.

Meeting Unique Regulatory Requirements

Given the vast number of SVOCs in existence, local regulatory agencies may require testing for compounds that are not explicitly listed under EPA 625/625.1 or SW-846 8270. In such cases, Teklab performs rigorous validation studies to determine if your specific compound can be accurately extracted and analyzed using recognized reference methods. This ensures compliance with NELAC accreditation standards and provides you with defensible data.

Understanding EPA 625/625.1 and SW-846 8270

EPA 625/625.1 and SW-846 8270 are both widely used methods for analyzing organic compounds in environmental samples, but they have different scopes and applications:

EPA 625/625.1: This method is primarily used for analyzing a broad range of organic pollutants in wastewater and other aqueous samples. It covers compounds such as:

• Pesticides
• Chlorinated Hydrocarbons
• Polynuclear Aromatic Hydrocarbons (PAHs)
• Phenols
• Phthalate Esters

The method involves extracting the sample with dichloromethane and then analyzing the extract using gas chromatography-mass spectrometry (GC-MS).

SW-846 8270: Method 8270D, part of the EPA’s SW-846 series for solid waste testing, is used to analyze semi-volatile organic compounds in various matrices, including water, soil, and solid waste. Typical contaminants analyzed using this method include:

• Base/Neutral/Acid Extractables (BNAs)
• Polychlorinated Biphenyls (PCBs)
• Dioxins and Furans
• Polycyclic Aromatic Hydrocarbons (PAHs)
• Organochlorine Pesticides

👉The method uses gas chromatography-mass spectrometry (GC-MS) to determine the concentration of semi-volatile organic compounds.

The Importance of NELAC Accreditation:

Teklab is a NELAC-accredited environmental testing laboratory. This accreditation signifies that we have met rigorous quality standards and demonstrated our competence in performing environmental analyses. Choosing a NELAC-accredited lab ensures that you receive accurate, reliable, and defensible data.

Selective Ion Monitoring (SIM): Enhancing Sensitivity and Defensibility:

Many remediation projects have cleanup objectives that require the lowest possible reporting limits while maintaining the legal defensibility of mass spectrophotometer detection. This combination can be challenging because complex sample matrices can damage the mass spectrophotometer.

📌To address this challenge, Teklab utilizes Selective Ion Monitoring (SIM) techniques. SIM is a specialized GC-MS technique that enhances sensitivity and selectivity for target analytes.

Benefits of SIM:

• Lower Reporting Limits: SIM allows for the detection of SVOCs at lower concentrations compared to traditional GC-MS methods.
• Reduced Matrix Interference: SIM minimizes the impact of matrix interference, improving the accuracy and reliability of results.
• Enhanced Defensibility: SIM provides enhanced data quality and defensibility, making it ideal for regulatory compliance and legal proceedings.
• Reduced Instrument Damage: By allowing for minimal dilutions, SIM reduces the risk of damage to the mass spectrophotometer from complex sample matrices.

Since GC/MS analysis is significantly more costly, the industry has developed Selective Ion Monitoring (SIM). The SIM technique allows environmental laboratories to analyze highly complex samples with minimal dilutions which results in minimal damage to the mass spectrophotometer. That allows low reporting limits and the enhanced defensibility of mass spectrophotometer analysis.
