AOTF-NIR Spectrometer (In-line Process)

The Brimrose Luminar 4030 AOTF-NIR Spectrometer is designed and built for in-line or at-line measurement in a production facility. The 4030 has a stainless-steel housing and is used in free space mode. The free space configuration is mounted to a blender, pipe, or over a conveyor at a fixed distance from the product so that the transmitted light reflects from the sample for optimal analysis.

 

Applications

• Blend Control: Real-time homogeneity monitoring and blending control process
• Drying Process: Direct placement on spray or fluid bed dryers
• Pharmaceutical: 100 percent inspection of solids, gels, liquids and powders
• Agricultural/Food: On-line food analysis for fat, protein, bread crumb, moisture, starch, etc.
• Polymer: In-site measurement of pellets, films and coatings
• Textile: Cotton/polyester ratio accurately by the web
• Pulp and paper: In-line thickness and coating analysis
• Tobacco: Measurements of moisture, nicotine, sugar, potassium, etc.
