Organic Testing

At Teklab, we excel in the precise analysis of a wide range of Semi-Volatile Organic Compounds (SVOCs) to meet the stringent requirements of industrial, municipal, and regulatory clients throughout the Midwest.

Comprehensive Analysis of Semi-volatile Organic Compounds

At Teklab, we specialize in the precise testing of a wide variety of Semi-volatile Organic Compounds (SVOCs) to meet the rigorous demands of industrial, municipal, and regulatory clients. Our advanced environmental laboratory routinely analyzes soils, waters, and special wastes using state-of-the-art methods, ensuring that every test we conduct is both accurate and reliable. From BNA and PAH testing to pesticides and herbicides, our comprehensive list of semi-volatile methods is designed to address your specific needs.

Understanding that many unique organic compounds exist, and local regulatory agencies may require testing beyond standard EPA or SW846 lists, Teklab performs validation studies to ensure your particular compound can be accurately extracted and analyzed. We pride ourselves on maintaining NELAP accreditation standards, providing you with trustworthy and legally defensible results. Whether your testing requirements are routine or specialized, Teklab’s commitment to quality and precision ensures that your environmental testing needs are met with the highest level of expertise.

What Are SVOCs?

Semi-Volatile Methods refer to a category of techniques or procedures used in various scientific and industrial applications, where the term semi-volatile implies that the substances involved can evaporate or vaporize under certain conditions, but not as readily as highly volatile substances.

📌The SW-846 methods, developed by the U.S. Environmental Protection Agency (EPA), are a set of standardized protocols designed for the analysis of hazardous substances in environmental samples such as soil, water, air, and waste.

  • The methods in SW-846 specifically address the identification and quantification of contaminants, including both volatile and semi-volatile organic compounds (SVOCs).

Definition of Semi-Volatile

👉Semi-volatile compounds are those that have an intermediate volatility.

They are not as easily evaporated as highly volatile substances (like alcohols or fuels), but they can still vaporize when subjected to certain environmental conditions, such as increased temperature or reduced pressure. Examples include certain pesticides, solvents, and environmental pollutants.

Application in Analytical Methods

🧪In the context of analytical chemistry, semi-volatile substances are often studied using specific techniques. These include:

Gas Chromatography
(GC):

  • Often coupled with mass spectrometry (MS), GC-MS is widely used to
    separate and identify semi-volatile organic compounds (SVOCs).

Industrial Use:

  • Semi-volatile methods are also used in industrial applications for quality control and detection of residual solvents or chemicals that are not fully volatile under typical conditions but can still affect product safety and quality.

Specialized Equipment:

To properly detect or analyze semi-volatile substances, specialized equipment and procedures are required, such as:

  • Thermal Desorption Units: To collect semi-volatile compounds from a sample by heating it.
  • Headspace Analysis: This method can analyze gases or vapors in the air above a solid or liquid sample, particularly for substances with semi-volatile properties.

Regulatory and Safety Implications:

  • Because semi-volatile compounds can have a
    significant environmental or health impact, their detection and monitoring are often subject to
    regulatory standards. For example, certain limits may be set on allowable levels of SVOCs in
    consumer products, drinking water, or air quality.

Example Use Cases For SVOC Testing:

  • Environmental Monitoring: Testing air or water samples for SVOCs to detect pollution.
  • Food Safety: Checking for semi-volatile pesticides or preservatives in food products.
  • Pharmaceuticals: Ensuring that semi-volatile solvents used in the production process are properly
    controlled and within safety limits.
