ASTM D7679 Hydrocarbons Extended Range GC Test in Water
The ASTM D7679 standard method is widely recognized and utilized for measuring hydrocarbons in water samples, particularly those extended-range compounds. This test is essential for industries dealing with oil and gas, petrochemicals, and wastewater treatment plants to ensure compliance with environmental regulations.
This service provides comprehensive analysis of hydrocarbon content in water, focusing on compounds that are not easily detected by conventional GC methods but are critical to monitor due to their potential impact on the environment. The extended-range GC test is particularly useful for detecting low-level concentrations and identifying specific compound types within the oil and grease spectrum.
The ASTM D7679 method uses a combination of sample preparation techniques, including solvent extraction followed by thermal desorption, to concentrate hydrocarbons prior to analysis. This ensures that even trace amounts of contaminants are captured for accurate quantification. The test is conducted using state-of-the-art gas chromatography equipment capable of resolving complex mixtures of hydrocarbon compounds.
The primary objective of the ASTM D7679 method is to provide a reliable and precise measurement of total petroleum hydrocarbons (TPH) in water samples, which includes both non-polar and polar hydrocarbon fractions. This service is particularly valuable for industries that must adhere to strict environmental standards, such as those involved in oil spill cleanup, wastewater treatment, and process water monitoring.
The results of the ASTM D7679 test are reported according to the standard's guidelines, which specify the use of both mass-based (mg/L) and volume-based units for TPH. This dual reporting ensures that clients can interpret the data in a manner most relevant to their specific applications.
Our laboratory adheres strictly to ASTM D7679 protocols, ensuring accurate and consistent results every time. We employ highly skilled technicians and use cutting-edge equipment to perform these analyses with precision and reliability. The service also includes detailed reporting of all findings along with recommendations for corrective actions if necessary.
Understanding the impact of hydrocarbons on water quality is crucial not only from an environmental perspective but also in terms of operational efficiency within industrial processes. By leveraging this advanced testing methodology, clients gain valuable insights into their water management practices, helping them make informed decisions to minimize risks and enhance sustainability.
