Selecting a light, or spectroscopy, based in-line process analyzer can be an intimidating task. We suggest you start by asking:
To aid you in the decision-making process, we developed a simple three-step process to answer these questions. Once these questions are answered, you can confidently move on to comparing technologies.

The first step in selecting the proper analyzer for an application is achieved by identifying what properties and chemical species of the process you want to monitor. Use the image below to locate as many wavelengths as possible that match the chemical structures of interest.
The discrete wavelengths for four common ClearView db applications:
Now that the wavelengths of interest have been identified, simply match those wavelengths to an analyzer that can measure them. The image above indicates the wavelength range covered by the UV-VIS 508plus Spectrometer, the NIR-O Full Spectrum Near-Infrared Analyzer, PCM1000, PCM 5000 and the Dual Beam Clearview Photometer. If less than 6 wavelengths were identified, then a ClearView db can possibly provide a cost-saving solution for real-time monitoring of process conditions.
Now you can compare some high-level specifications such as the number of simultaneous sample points, wavelength range, technology type, the number of traits or answer the analyzer can monitor at each sample location.
