Spectroscopic Analyzer for Chemical Manufacturing

Product Specifications

Technical details and manufacturing context for Spectroscopic Analyzer

Definition

A spectroscopic analyzer is a critical component within Process Analytics systems that uses spectroscopic techniques (such as UV-Vis, NIR, IR, Raman, or atomic spectroscopy) to monitor and analyze chemical compositions, concentrations, and physical properties of materials in real-time during industrial processes. It enables continuous quality control, process optimization, and regulatory compliance by providing non-destructive, rapid measurements without requiring sample extraction. The analyzer typically includes a light source, a sample interface, a wavelength selector (such as a diffraction grating), and detectors (e.g., photodiode or CCD). It is designed for integration into chemical manufacturing lines, where it provides continuous data for process control. The unit operates over a wavelength range of 190–1100 nm, with spectral bandwidth adjustable from 0.5 to 5 nm, and wavelength accuracy of ±0.5 nm. Photometric accuracy is ±0.005 AU, and stray light is ≤0.05 %T. The detector type is CCD, and the light source is xenon. Operating temperature range is 15–35 °C, and humidity is 20–80 %RH (non-condensing). Power supply is 100–240 V AC, 50/60 Hz, with power consumption ≤150 W. The benchtop unit weighs 15–25 kg and has dimensions of 450×350×250 mm (W×D×H). Interfaces include USB and Ethernet for data transfer and remote control. The housing is stainless steel, and optical components include optical-grade quartz and diffraction gratings. This analyzer is intended for use in chemical manufacturing environments where real-time composition monitoring is required. It is not a complete process analyzer system but a component that must be integrated with appropriate sampling and data systems. For specific applications, verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The analyzer emits electromagnetic radiation (light) toward the sample material. The sample absorbs, reflects, or scatters specific wavelengths based on its molecular structure and composition. Detectors measure the resulting spectrum, and algorithms compare it to reference libraries to identify substances and quantify concentrations. Common techniques include absorption spectroscopy (measuring absorbed wavelengths), emission spectroscopy (measuring emitted wavelengths), and scattering spectroscopy (measuring scattered radiation). The instrument uses a xenon light source and a diffraction grating to disperse light, with a CCD detector capturing the spectrum. The measured spectrum is then analyzed to determine material properties.
