Get more information about the standard at ASTM E1655-17.
ASTM E1655 is a standard practice that provides guidelines for the multivariate calibration of infrared (IR) spectrometers. This practice is essential for determining the physical or chemical characteristics of materials through quantitative analysis using near-infrared (NIR) and mid-infrared (MIR) spectroscopy. By outlining procedures for data collection, calibration development, and validation, ASTM E1655 ensures the accuracy and reliability of IR spectroscopic measurements across various industries.
Details
The ASTM E1655 practice provides a comprehensive guide for developing multivariate calibrations of IR spectrometers to determine material properties accurately. The practice involves several critical steps:
- Data Collection: Acquiring spectral data from samples using IR spectrometers.
- Calibration Development: Utilizing statistical methods to correlate spectral data with known physical or chemical properties, creating a multivariate calibration model.
- Validation: Assessing the model’s performance by comparing predicted results with actual measurements to ensure accuracy and precision.
- Implementation: Applying the validated model to predict properties of unknown samples in various settings, including laboratory and industrial environments.
