Model Maintenance and Customizing a Starter Model to Meet Your Operational Needs

A complete online process monitoring system includes an analyzer, sample interface, and fiber optic cables. The instrument also requires calibration for each application. Guided Wave often provides a starter or factory calibration. Given the variation in process stream composition, it is highly recommended to perform model updates to customize the factory calibration for each installation. […]

NIR Process Analyzers for Refineries

Refineries process crude oil into usable petroleum based chemicals. Process analyzers such as ATOM INSTRUMENT’s Flare Gas Analyzer, SOFRASER’s Thermoset Viscosity Analyzer, Guided Wave’s Near Infrared Spectrometer/Photometers, and in-situ sample interfaces are all necessary for real-time monitoring in a profitable modern refinery. By installing and calibrating these process analyzers, technicians and plant managers gain access […]

Temperature Controlled Flow Cell for At-Line FT-NIR Measurements

GUIDED WAVE’S Multi-Purpose Flow Cell for FT-NIR analyzers is also available with internal tubings for heating or cooling fluid. While the heat exchanged is not sufficient to impact a rapidly flowing sample, it can be used to maintain the temperature of a preconditioned sample. Why Controlling The Temperature of the Sample Interface Matters? Some applications such as […]

NIR Analyzers for Polyurethane Synthesis

Polyurethane manufacturing is a high-temperature process conducted under hazardous conditions. A safe and cost-effective method to monitor the polymer synthesis is Near Infrared (NIR) analysis. Using remote insertion probes connected to a NIR analyzer with intrinsically safe fiber optic cables protects the operator from potential safety risks compared to the use of grab samples or […]

  • Guided Wave provides support for application development and feasibility studies.

Why Use Process Analytical Spectroscopy for Real Time Monitoring?

Traditionally, absorption spectroscopy has been used in laboratories to perform the precise analyses of samples. In recent years, as electronic circuitry and optical components have become more refined, a more robust portion of the electromagnetic spectrum—UV/VIS/NIR—has emerged for use in process analytical technology. No other technology matches the acquisition speed and the range of measurements returned by a fiber optic-based dispersive grating spectrometer. A comprehensive set of data that takes hours of laboratory analyses to acquire can be available in about a minute with a process spectrometer.

Process Analytical Technologies (PAT) have been field proven for almost three decades. It is typical for a Guided Wave scanning spectrometer running 24/7 to last more than 10 years with >99% uptime. The maintenance requirements for process spectrometers are also minimal in comparison to other monitoring techniques (for example, process gas chromatographs and online titrators). The return on investment and the low cost of operation make Guided Wave analyzers a sensible and proven choice.

Flow Cells for FT-NIR Process Spectrometers

Both the standard Multipurpose Flow Cell and the Heated Flow Cell are manufactured by Guided Wave to facilitate full integration with any fiber-optic spectrometer manufacturer. The Heated Flow Cell is fully compatible with the Matrix-F FT-NIR analyzer, ABB’s full line of FT-NIR spectrometers, Metrohm’s NIRS XDS Process Analyzer, and AIT’s optical analyzers. The market-leading optical efficiency of Guided Wave’s sample interfaces will improve the optical performance of any spectrometer (PAT) when connected with 400 to 600 micron fiber optical cables and SMA 905 or FC connectors. The family of Single-Sided Transmission probes (SST) and the shuttle probe are compatible with process spectrometers from any FT-NIR vendor.
