About This Item
ASTM D5790 is the ASTM standard for measuring purgeable organic compounds in water by capillary column gas chromatography/mass spectrometry. It provides a structured analytical approach for identifying and quantifying volatile or easily purged organic constituents in water samples. This matters for laboratories and water-quality programs that need consistent test results, reliable comparison data, and a recognized technical basis for reporting organic contamination using GC/MS methods.
Purpose of ASTM D5790
The purpose of ASTM D5790 is to define a test method for analyzing purgeable organic compounds in water with capillary column gas chromatography/mass spectrometry. As an ASTM standard, it supports a repeatable laboratory workflow for sample preparation, separation, detection, and measurement. This helps users apply a common method when evaluating water for organic constituents that can be removed by purging and then measured through GC/MS instrumentation.
Common use cases of ASTM D5790
This standard is commonly used in laboratory testing of water samples where purgeable organic compounds must be measured with analytical consistency. It is relevant to quality control laboratories, environmental testing workflows, and compliance-oriented sample analysis that rely on gas chromatography/mass spectrometry. ASTM D5790 may also support method selection, instrument validation, and routine reporting when a documented standard test method is needed for water analysis.
Why ASTM D5790 matters
ASTM D5790 matters because it helps create consistency in how purgeable organic compounds are measured in water. Using a recognized standard test method can improve comparability between labs, reduce ambiguity in procurement and contract specifications, and support more dependable quality control decisions. For organizations that depend on analytical results, the standard provides a clear technical reference for testing, performance expectations, and defensible reporting.
