About This Item
ASTM D3695 is the standard test method for measuring volatile alcohols in water by direct aqueous-injection gas chromatography. It provides a consistent approach for identifying and quantifying alcohols that may be present at low levels in water samples, supporting reliable analytical results. For laboratories and quality-focused organizations, this standard helps reduce variation in testing and improves confidence in reported data when volatile alcohol content needs to be checked for compliance, process control, or product evaluation.
ASTM D3695 standard overview
The official title, Standard Test Method for Volatile Alcohols in Water by Direct Aqueous-Injection Gas Chromatography, shows that the method is built around direct injection of an aqueous sample into a gas chromatograph. That makes ASTM D3695 relevant to laboratory analysis where water is the sample matrix and volatile alcohols are the target analytes. The standard is intended to support structured, repeatable testing practices, giving users a common technical reference for sample handling, instrument use, and result reporting.
Where is ASTM D3695 used?
This standard is commonly used in analytical laboratories that evaluate water samples for volatile alcohol content. It may be applied in quality control workflows, product testing programs, or compliance-related investigations where accurate measurement of alcohols in water is needed. ASTM D3695 is especially useful in settings that rely on gas chromatography and routine laboratory methods, since it helps align testing practice with a recognized ASTM procedure for direct aqueous-injection analysis.
Practical importance of ASTM D3695
ASTM D3695 matters because it supports consistent measurement of volatile alcohols in water using a defined test method. That consistency is important for comparing results across laboratories, maintaining quality control, and documenting compliance-related data. Using a recognized ASTM standard can also help reduce ambiguity in procurement and technical specifications, since buyers, sellers, and testing labs can reference the same method when evaluating water samples and reporting analytical performance.
