Probes & Flow Cells / Fiber & Accessories

For our NIR UV-VIS PROCESS AND LAB ANALYZER (SPECTROMETERS) 

The sample interface is a virtual “window into the process” and is a critical component of any optical analyzer system. Our GUIDED WAVE™ sample interfaces (probes, flow cells) are designed for use with our NIR UV-VIS fiber optic coupled analyzers. They are rugged and reliable, especially in harsh chemical and physical process conditions and provide optimal transmission for long-term reliable measurements.  Our inline probes are the most cost-effective and trouble-free solution for your real-time process spectral analysis.

We offer a range of sample interfaces (probes and flow cells) that are designed with unique features to ensure accurate and reliable measurements in a variety of applications. One unique feature of our sample interfaces is their flexibility in design. They can be customized to fit specific process requirements, such as temperature and pressure, and to accommodate various sample types, including liquids, slurries, and gases. Additionally, they are designed to be easy to install and maintain, minimizing downtime and reducing operating costs.

SAMPLE INTERFACES

Our GUIDED WAVE sample interfaces, including probes and flow cells, are used in a variety of applications across multiple industries. They are commonly used for in-line process measurements in the chemical, petrochemical, oil and gas, food and beverage, pharmaceutical, and environmental industries.

In the chemical industry, these interfaces are used for process monitoring and control, including the measurement of reaction kinetics and product quality. In the oil and gas industry, they are used for the measurement properties, such as density, viscosity, and other physical/chemical properties.

In the food and beverage industry, the interfaces are used for quality control, including the measurement of moisture, fat, protein, and sugar content. In the pharmaceutical industry, they are used for drug development, process monitoring, and quality control.

In the environmental industry, the interfaces are used for water quality monitoring, including the measurement of organic compounds and nutrients in wastewater treatment plants. They are also used for air quality monitoring, including the measurement of volatile organic compounds (VOCs) and other air pollutants.

Where can you find spectroscopic probes or flow cells in custom designs, certified for strict engineering compliance, compatible with most analyzer manufacturers, and at a competitive price? With average delivery times of 6 weeks or less, GUIDED WAVE’S rugged sample interfaces meet these challenges. Additionally, these probes and flow cells are designed specifically for operation in extreme environments and are among the highest optically efficient designs on the market. 

CORROSIVE MATERIAL? DOESN’T MATTER WITH THIS CUSTOM FLOW CELL

With a long history of designing custom probes and flow cells to meet specific or unique customer applications and challenges, the toughest (and most expensive) flow cell ever built by GUIDED WAVE was recently released. The reason for the high price is that it is made from B2 Hastelloy®, a rare material used only for the most severe chemical processes. Hastelloy, a nickel alloy, is a more exotic and expensive material than stainless steel typically used for standard flow cell body construction. Hastelloy is usually the best alternative when dealing with an extremely corrosive process stream, and stainless steel is deemed unsuitable for the process.

PYROPHORIC FIRES A CONCERN? EXTINGUISH YOUR WORRIES 

For most customers, our innovative- first in the industry, built-in cleaning port is a welcomed feature of our flow cell. It allows the cell’s sapphire windows to be cleaned by simply removing a clean-out plug. This direct access to the windows without disconnecting process lines or fiber optic cables is convenient and makes maintenance easier and more cost effective. However, a recent customer came to us with a pyrophoric process. Their process cannot tolerate the possibility of the flow cell cleaning port being accidentally opened, exposing the stream to outside air. As a result, Guided Wave designed a new flow cell without the window to relieve safety concerns and to remove the “what ifs?”

Whether standard or custom designs, many Guided Wave probes can be optimized for the UV, Visible or NIR spectral regions or supplied with custom fiber diameters and connectors to match a variety of optical requirements. Guided Wave also supplies probes manufactured in compliance with the American Society of Mechanical Engineers (ASME) or Canadian Registration Number (CRN) pressure vessel standards.

CRN CERTIFIED PROBES FOR PROCESS SPECTROSCOPY

Several GUIDED WAVE probes and flow cells have Canadian Registration Number (CRN) certification. A CRN is a number issued to the design of a pressure vessel or fitting by each province or territory of Canada. The CRN identifies that the design has been accepted and registered for safe installation and use. CRN certified probes and flow cells are engineered by Guided Wave to meet the strict safety and application requirements for the Canadian petrochemical, refining, and polymer markets. By coupling these probes with certified (CSA, ATEX, IECEX) process analyzers, GUIDED WAVE can offer complete process monitoring solutions to Canadian customers. Guided Wave currently has CRN registered designs for Ontario, Alberta and Quebec. However, complete process monitoring solutions for all provinces can be implemented – contact us for more information. All CRN probe designs include hydrotest and x-ray test results.

I’M NOT USING A GUIDED WAVE ANALYZER; IS THE SST PROBE COMPATIBLE WITH MY BRUKER ANALYZER?

Not using a Guided Wave analyzer, no problem. Our probe and flow cells are compatible with most analyzers on the market.

LARGE VARIETY OF COMPATIBLE PROBES AND FLOW CELLS

Guided Wave offers a variety of probes, flow cells and fiber optic cables that meet the harsh demands of the process environment. Several have auxiliary features and are compatible with all GUIDED WAVE analyzers as well as other fiber optic-based analyzers manufactured by different companies. Examples are; ABB, ANALECT, Bruker and Yokogawa. At GUIDED WAVE if we do not have a probe or flow cell that meets your precise needs, we will look at your application, judge its feasibility, and make recommendations on how to proceed.
