We deliver a total solution that includes optically matched components and a well-planned calibration approach leading to long-term client success and user savings. Our state-of-the-art systems are designed for continuous online use, providing real-time lab-quality data, while thriving in the most demanding processing plant environments. Our product reliability, stable instruments and responsive technical support are why companies around the world depend on Guided Wave.

Guided Wave partners with you to configure the optimal system for your challenging process measurement needs.

Online monitoring delivers the power you need to drive optimal production. The real-time benefits of Guided Wave technology include a reduction in lag times between production and the elimination of off-spec material that typically requires rework, or scrap. Guided Wave, a company you can count on for control you can measure.

Powerful. Reliable. Customizable.

Guided Wave analyzer systems consist of rugged, yet highly efficient sample interface designs that are remotely coupled to the spectrometer or photometer at a safe distance from common areas. Additionally, our analyzers can be fitted with optional equipment making them suitable for deployment in areas classified as hazardous. Even after installation, safety benefits continue. Built-in interpretive diagnostics notify operations instantly of potentially dangerous changes to the chemical composition of your process.

Guided Wave analyzer systems provide real-time characterization of the stream, allowing for the most efficient and effective processing. Production rates and delivery schedules are more consistently achieved, providing better resource planning for your company and ultimately your customers. Most importantly, because of the access to real-time data, the quality of your product is never in question

We work with you to tailor a solution for your exact requirements, from analyzer to interface, with competency in applications that cover a wide span of industries:

Guided Wave products provide continuous analytical monitoring of your process, delivering the data you need, when you need it. Our product line includes optical probes and flow cells, photometers, fiber cables, full-spectrum spectrometers, sampling systems, and data analysis software, all with a two-year warranty. At Guided Wave, all products are tested in system configurations to ensure optimal transmission and full compatibility.

  • Guided Wave manufactures all of the analyzer subassemblies, ensuring consistent quality, accuracy, safety and reliability.
  • Guided Wave systems are easy to install and service, and come with assistance, training and after-installation support.
  • Guided Wave provides support for application development and feasibility studies.

Analyzers:  Spectrometers
Guided Wave produces the best multiplexed spectrometric analyzers in terms of signal-to-noise ratio, providing more robust calibrations and less maintenance.

  • Full-spectrum analyzers cover a wide range of wavelengths, from UV/VIS through the near-infrared.
  • Process data available to your control system in seconds.
  • Exceptional performance with laboratory precision and accuracy in rugged, field tested instruments.
  • Single or multiple, independent sampling points with one analyzer

Analyzers:  Photometers
Guided Wave’s economical photometers are designed for well characterized applications where only a few wavelengths are needed. Easy to calibrate and install, they are the simple solution.

  • 1-2 independent sample points.
  • Class 1 Division 1, Class 1 Division2, ATEX and IECEx enclosures.
  • Small footprint; install without major changes to existing structures.
  • Minimal plant utilities and cost of operation; no instrument air, nitrogen or potable water needed. (Dependent on area classification, for example, Z-purge; C1 Div2).

Sample Interfaces
Guided Wave robust sampling interfaces are reliable in harsh, challenging conditions. Our probes, flow cells and fiber optics are engineered to optimize total analyzer performance, giving you better data for better decisions.

  • Fiber optic sample interfaces are available for both liquid and gas streams.
  • Best light energy transmission efficiency in commercially available interfaces.
  • Our specifications typically call for 50% better throughput than other commercially available interfaces.
  • In-house custom probe and flow cell design for bypass loops and slip streams.
  • Patented high-performance optical fiber cabling with rugged Tefzel™ Kevlar™

Why use NIR and UV/VIS?

Traditionally, absorption spectroscopy has been used in laboratories to perform precise analysis. 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 process analytics. No other technology matches the acquisition speed and the range of measurements returned by a fiber optic-based spectrometer. A comprehensive set of data that takes hours of laboratory analyses to acquire can be available in about a minute.

These workhorse analyzers 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 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.

The power of online monitoring using NIR

In 1983 Guided Wave was recognized as an industry leader when it delivered the first fiber optic-based NIR analyzers. Today, Guided Wave is the only process NIR vendor that provides a complete optically matched system, yielding the best throughput efficiency and long-term performance that exceeds industry standards.

The team at Guided Wave is accessible and responsive, offering insightful solutions to your application questions, innovative designs, expert technical support and knowledgeable service. ISO 9001 certified, Guided Wave maintains global support and certified technical distributors worldwide. We stay with you through the lifetime of the product to ensure you get better data for better decisions.
