ASTM E2787

ASTM E2787 is the ASTM standard for determining thiodiglycol in soil using pressurized fluid extraction followed by single reaction monitoring liquid chromatography/tandem mass spectrometry (LC/MS/MS). It provides a defined analytical approach for extracting and measuring the target compound in soil samples, helping laboratories generate consistent results for testing and review. By pairing controlled extraction with LC/MS/MS detection, this standard supports more reliable evaluation of soil samples where thiodiglycol analysis is needed.

What is ASTM E2787?

ASTM E2787 is a laboratory test method focused on the determination of thiodiglycol in soil. The standard describes an approach that uses pressurized fluid extraction to isolate the analyte from the soil matrix, followed by single reaction monitoring LC/MS/MS for measurement. This technical framework is important because it establishes a repeatable workflow for sample preparation and instrumental analysis. As an ASTM standard, it helps align testing practices so results are more suitable for comparison, documentation, and quality-focused decision-making.

Where is ASTM E2787 used?

This standard is typically used in laboratories that analyze soil samples for thiodiglycol using extraction and mass spectrometric methods. It may be relevant in environmental, forensic, or other technical testing workflows where soil composition or contamination assessment requires a targeted analytical method. ASTM E2787 is most useful where pressurized fluid extraction and LC/MS/MS instrumentation are part of the established process, and where a defined test method is needed to support controlled sample handling and reporting.

Why is ASTM E2787 important?

ASTM E2787 matters because it gives laboratories a structured method for measuring thiodiglycol in soil with greater consistency. A clear standard can support compliance, improve repeatability, and reduce uncertainty in procurement, testing, and quality control decisions. It also helps organizations compare results from different samples or runs using a common technical basis. For teams that rely on analytical data, this kind of standard can be valuable for documentation, method selection, and risk reduction.
