Application of Infrared Spectroscopy for the Determination of Hydroxyl Content in Quartz Glass
The continuous melting process is one of the most widely adopted manufacturing methods for quartz glass production. Hydrogen gas (H₂) is introduced as a protective atmosphere to prevent oxidation of the tungsten heating elements at elevated temperatures. during melting, thereby improving the optical quality of the quartz glass.
Infrared spectroscopy provides a reliable method for the qualitative and quantitative determination of hydroxyl content in quartz glass. This analytical technique offers significant advantages, including rapid measurement, high sensitivity, convenience, and excellent accuracy.
Infrared Spectroscopy Application in Pharmaceutical and Chemical Industries
In the pharmaceutical and chemical sectors, both raw materials (including excipients) and finished products encompass a broad range of compounds and complex manufacturing processes. Many pharmaceutical substances possess intricate molecular structures or only subtle structural differences, Infrared (IR) spectroscopy is recognized as a highly selective and effective analytical technique for the characterization of organic compounds.
