Overview
ASTM E2043-99(2021) - Standard Test Method for Nonvolatile Matter of Agricultural Adjuvant Solutions by Thermogravimetry is an internationally recognized standard developed by ASTM International. This test method provides a systematic approach for determining the nonvolatile matter content in agricultural tank mix adjuvant solutions using thermogravimetric analysis. The standard supports quality control, material screening, and problem solving within the agricultural chemicals sector, ensuring consistent and reliable assessment of nonvolatile residues in adjuvant formulations.
Key Topics
- Nonvolatile Matter Determination: This standard outlines the steps for measuring nonvolatile matter, defined as the remaining residue after heating an agricultural adjuvant solution under controlled temperature and time conditions.
- Thermogravimetric Technique: The method employs thermogravimetry to record mass loss as a function of time and temperature, allowing for precise quantification of nonvolatile components.
- Quality Control and Material Evaluation: ASTM E2043-99(2021) is primarily intended for use in routine quality assurance, comparing unknown samples to reference standards, and supporting investigations of process deviations or formulation consistency.
- Adaptability: The parameters described in the method may be modified to suit specific analytical needs, provided all changes are documented in the test report.
- Safety and Compliance: Users are responsible for following appropriate safety, health, and environmental protocols, and for considering any regulatory limitations applicable to their testing environment.
Applications
ASTM E2043-99(2021) has practical value across multiple areas within the agriculture and agrochemical industries:
- Agricultural Adjuvant Testing: Provides a reliable procedure for evaluating the purity and consistency of adjuvant solutions used in tank mixtures for crop protection and yield enhancement.
- Quality Assurance in Manufacturing: Enables manufacturers and formulation chemists to verify that batches of adjuvant solutions meet defined specifications for nonvolatile content, helping ensure product performance and regulatory compliance.
- Material Comparison and Screening: Facilitates side-by-side comparison of different formulations or new product candidates by quantifying nonvolatile residues.
- Problem Solving: Supports troubleshooting in cases of suspected product contamination, evaporation losses, or ingredient volatility during storage and handling.
- Regulatory Documentation: Assists stakeholders in providing data for regulatory submissions, product registrations, and compliance audits where knowledge of nonvolatile matter is relevant.
