Optical Analysis

Optical Analysis

Optical analysis includes laboratory and process optical systems used to identify and quantify compositions across solids, liquids, slurries, particles, and gases. Endress+Hauser positions this portfolio as a comprehensive set of atomic and molecular analysis tools supporting laboratory work, in-process monitoring, and emissions monitoring—enabling real-time insight into product quality and emissions behavior.

Key technologies span both extractive and in-situ measurement approaches. Listed methods include tunable diode laser absorption spectroscopy (TDLAS), quenched fluorescence (QF), Raman spectroscopy, NIR, IR, UV/Vis, and atomic absorption—covering a wide spectrum of analytes, matrices, and installation models.

The category structure includes TDLAS and QF analyzers, Raman spectroscopic systems, emission monitoring solutions, particle measuring devices, digital analyzer solutions, process gas analyzers, air quality measuring devices, smoke detectors, visual range measuring devices, and overheight detectors. This breadth supports both process optimization and environmental/ambient monitoring requirements within one analysis framework.

Benefits of optical analysis emphasize process transparency, real-time measurement (seconds to minutes), and non-invasive inline measurement that is efficient and non-destructive without sample preparation or handling. High plant availability is supported through optical systems positioned as easy to operate and maintain, while compliance objectives are supported through reliable gas concentration monitoring for targeted emissions minimization.

Typical applications include gas-phase measurement for process safety and quality control, in-process compositional monitoring for rapid decision-making, particulate and opacity-related monitoring, and continuous emissions monitoring workflows. System design commonly evaluates in-situ vs. extractive architecture, installation environment, maintenance access, validation strategy, and integration of analyzer outputs into broader data and control environments.
