ASTM D7066 Oil Petroleum Infrared Test in Water
The ASTM D7066 test procedure is a critical method used to determine the oil and grease content in water samples. This infrared-based technique provides accurate quantification of petroleum hydrocarbons present in aqueous environments, ensuring compliance with environmental regulations.
This service is particularly important for industries such as wastewater treatment plants, refineries, and chemical manufacturing facilities that deal with large volumes of effluent containing organic compounds. By monitoring the oil content levels, operators can take necessary corrective actions to prevent pollution and ensure safe discharge into natural water bodies.
The ASTM D7066 method uses near-infrared (NIR) spectroscopy to analyze the sample. It involves specific wavelengths that are characteristic of petroleum hydrocarbons, allowing for precise identification and quantification. The process typically begins with proper sampling techniques to ensure representative samples are collected from different points within the water body.
Preparation of these samples often requires filtration or other purification methods to remove particulate matter and achieve a clear liquid phase suitable for analysis. Once prepared, the sample is introduced into an infrared spectrometer where its spectrum is measured. The resulting data allows for comparison against known standards, facilitating accurate determination of oil content.
The ASTM D7066 protocol emphasizes rigorous quality assurance practices to maintain reliability and consistency across various testing scenarios. These include standard operating procedures (SOPs) for sample preparation, calibration of equipment, and interpretation of results. Regular audits and validation exercises help ensure that all steps comply with established guidelines.
The application of ASTM D7066 extends beyond mere compliance; it also plays a crucial role in process optimization within industrial settings. By providing detailed insights into the presence and concentration levels of oil contaminants, this testing service enables proactive management strategies aimed at minimizing waste generation and improving overall efficiency.
