Trace measurement of water in alcohols is crucial for various industries, as water affects product quality, safety, stability, process efficiency, and equipment lifetime. Near Infra-Red (NIR) absorption is a popular analytical method for determining water content. The method is instantaneous, accurate, and does not require hazardous reagents that need regular refilling, making it the most desirable method for determining water content.
In comparison, the traditional Karl Fischer titration technique is slow, maintenance-intensive, and unsuitable for continuous in-line use in a chemical process. In-line NIR absorption overcomes these limitations, providing an accurate, cost-effective, and reliable method for water content determination.
The Kemtrak NIR analyzer measures in two regions. The 1400 nm region is used for measuring 1–100% water with a full-scale resolution of ±0.05%, and the 1900 nm region is used for 100–20,000 ppm trace water analysis with a resolution of ±10 ppm.
