Custom, Certified, and Compatible - Probes and Flow Cells for Extreme Environments

Where can you find FT-NIR and NIR spectroscopic probes or flow cells in custom designs, certified for strict engineering compliance, compatible with most analyser 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 utilise carefully designed optics, that are among the highest optically efficient designs on the market. 

Corrosive Material? Doesn’t Matter with this Custom Flow Cell

With over 30 years of designing experience 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, Guided Wave’s innovative- first in the industry, the built-in flow cell cleaning port is a welcomed feature. 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 had a pyrophoric process, which cannot tolerate the possibility of the flow cell cleaning port being accidentally opened, exposing the stream to the 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?”

CRN Certified Probes for Process Spectroscopy

Guided Wave also supplies probes manufactured in compliance with the American Society of Mechanical Engineers (ASME) or Canadian Registration Number (CRN) pressure vessel standards. More than 3,500 different design configurations for probes and flow cells have been submitted for the CRN certification. A CRN is a number issued to the design of a pressure vessel or fitting by each province or territory of Canada. It 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 analysers, Guided Wave can offer complete process monitoring solutions to Canadian customers, and currently has CRN registered designs for Ontario, Alberta, and Quebec.

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 analysers as well as other fiber optic-based analysers manufactured by different companies, such as ABB, AIT Schneider Electric, Bruker, Metrohm, Modcon, and Yokogawa. Contact Guided Wave for sample interface questions or requirements.
