Application Notes
  • Targeted Range Analysis - Introduced at EAS, "Using Axsun's high-resolution NIR Analyzer, we can target specific portions of the spectrum for use in qualitative and quantitative analyses. The first overtone regions of the carbon-hydrogen stretching and the oxygen-hydrogen stretching modes are well-suited for this purpose, because all organic compounds (aliphatic and aromatic), in all phases (gas, liquid, and solid) have specific and distinct bands in this region. Axsun spectrometers are also essentially identical, allowing direct transfer of quantitative analysis models from spectrometer to spectrometer." Application Note
  • Designing a Miniature Spectrometer - "This technical note compares the technologies available for rugged, miniature spectrometers designed for process applications, and will demonstrate that the high-performance requirements of distributed process control in harsh manufacturing environments demand an entirely new class of devices - specifically, Axsun's NIR micro-spectrometer line." Application Note
  • Liquid Phase Quantitative Analyses Using Axsun's Targeted-Range Near-Infrared Spectrometers - "Axsun's NIR spectrum analyzers provide extremely accurate, high-speed data acquisition with reproducible spectral output, for real-time measurements at high spectral resolution. With these features, the Axsun NIR Analyzer supports qualitative and quantitative analysis of liquid-phase systems. All organic solvents have very specific overtone bands in the first carbon-hydrogen stretching region, from 1600 to 1800 nm and this targeted range is sufficient for these analyses."
