| The Use of Fourier Transform Near-infrared Spectroscopy to Measure Hydroxyl Value, Acid Number and Other Parameters Important to Polyol Production (ISN:0022) |
| Abstract: FT-NIR spectroscopy has become the method of choice for the determination of hydroxyl value and other elated parameters in polyols. |
| Hydroxyl value and other elated parameters are very important QC measurements for manufacturers and users of polyols. Traditionally, these properties have been measured by titration methods. In the past five to ten years, near infrared (NIR) spectroscopy has become the method of choice for these determinations.
This note describes the use of Fourier transform near-infrared (FT-NIR) spectroscopy for these measurements. Examples are provided to demonstrate the precision and accuracy that can be expected when the Antaris FT-NIR Analyzer is employed for these routine quality control measurements.
