Guided Wave specializes in on-line optical measurements for process analytical chemistry. We design complete NIR and UV/VIS instrument systems and sample conditioning systems that are used continuously, on-line, in real-time under the rigors of the manufacturing plant environment.

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

Guided Wave Inc is a subsidiary of Advanced Holdings Ltd (“Advanced”). Advanced was started in 1993 to create a niche business by combining its engineering expertise in the supply of process technologies and equipment. SESDAQ-listed Advanced has today established itself as an ISO9001:2008 certified specialist company which designs, licenses and supplies proprietary process equipment and process technologies to cater to the different needs of its customers in the chemical and petrochemical, oil and gas, power generation and micro-electronics industries. The Advanced Group has offices and presence worldwide to serve the needs of its global customers.

Advanced's 4-pronged Corporate Strategies drives its corporate initiatives and business activities; namely –

  • Organic Growth

GWI collaborates with each customer to develop individualized solutions, from complete analyzer to interface systems, specifically tailored for each unique application.

Guided Wave’s extensive experience with process analyzer systems allows us to work with you to determine the best solution for your testing needs. We quickly assess feasibility based on our extensive experience and/or sample spectra from your process and determine which spectral analysis is best for your application (NIR/UV/VIS).

We work with you to choose the spectrometer or photometer package that works best for your budget and analysis needs, taking into account the number of sample points, the components being measured and their relative concentrations, the safety of your employees and the integrity of your manufacturing process. Our customized probes allow you to choose a measurement system best suited for your process environment, such as flow cell for slip streams or insertion probes for large pipes or reactor vessels.

Since we manufacture and test the entire integrated analyzer system you can be sure that you are receiving an optimized system that requires minimal upkeep or maintenance. We also provide installation assistance, training and after-installation support. Our commitment to the integrity of your process coupled with the quality of our analyzer systems is why our clients trust us with their most critical products.

  • GWI is the one stop shop for hardware. We are in full design control of the analytical system and are not dependent on other integrators. Because we build all of the analyzer components ourselves, we can ensure accuracy, safety and reliability.
  • GWI produces the best-multiplexed spectrophotometric analyzers in terms of signal to noise, providing more robust calibrations and less maintenance.
  • Our 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 more control.
  • Our systems are easy to install and service.

Choose GWI for our RELIABILITY ... Our field-proven, rugged instruments provide process control, worker safety, reliable data, and reduced sample handling with low maintenance and reduced cost of ownership.

NIR Benefits

Traditionally, spectroscopists have used IR or UV/VIS for testing the chemical composition of a variety of material, considering NIR to be a less useful portion of the spectrum. The broad, overlapping peaks in NIR make it more difficult to determine chemical components the way IR does. So why use NIR?

With the advent of brighter light sources and more sensitive detectors in the 1980’s, the benefits of NIR became more apparent. Spectral peaks can now be more accurately measured, resulting in usable data for spectral analysis. NIR optical paths are much larger than those for IR, which allows for probe cleaning and servicing. This technology improvement spurred the commercial production of spectrometers in the 1980’s.

The key benefits of a spectrometer include the ability to quickly and accurately measure samples while keeping the main analyzer away from any potentially dangerous processes. Fiber cables from the probes to the analyzer make this possible, but also introduce potential error sources for light measurement. Because the light must travel from the spectrometer to the optical probe and then back to the spectrometer for analysis, it is especially important that all the components in the analyzer system be tuned to work efficiently with each other. At Guided Wave all fiber cables, spectrometers, photometers and optical probes are all tested to ensure optimal transmission and compatibility. The improved transmission causes the NIR peaks to be more accurate and thus more accurately analyzed.

More advanced mathematics analysis techniques must be employed for NIR spectral data than for IR analysis. Multiple linear regressions (MLRs) and partial least squared regressions (PLRs) are used to analyze spectral peaks and glean useful data. Guided Wave offers software to help with the analysis process, and will work with you to calibrate and maintain your analyzer system.

While the subtlety of NIR peaks makes analysis slightly more complicated, the ability to have near-instantaneous results reduces reworking costs and improves product quality and process efficiency. The larger probe pathlengths allow the probes to be serviced and cleaned easily, and the analyzer can be placed further from the process due to excellent fiber cable transmission. For specific applications, less expensive photometer packages are useful and cost 25-50% less than a spectrometer system. Our optimized Guided Wave analyzer system and advanced mathematical analysis techniques make NIR a practical tool for your data analysis needs.

Near-infrared spectroscopy can provide fast, accurate results for your process without the high maintenance costs or the extensive upkeep considerations associated with gas chromatography. We use our optical technology to bring light to the sample, eliminating the costly sample systems and fast loops needed for process gas chromatography while providing faster results to you.

GC analysis costs approximately $35,000 per year in maintenance cost, which could be reduced 80-90% by replacing it with a Guided Wave analyzer system. Allow our streamlined, accurate NIR system to reduce costs and hassle for your company.

GWI has implemented and maintains a Quality Management System. Our quality policy strives to supply a reliable, accurate and cost effective solution to satisfy our customer requirements and to achieve continuous improvement in the quality of our products and operations. GWI is ISO 9001 certified.
