Its suite of products includes both portable analyzers and inline sensor modules that leverage ultraviolet absorption and fluorescence detection to measure concentration, purity, particle size and water content in liquids and gases. The company’s patented technology is deployed across a range of industries, including oil and gas, petrochemicals, pharmaceuticals and food and beverage, where real‐time measurement can improve product quality and operational efficiency. Coretec’s sensors utilize proprietary fiber optic probes coupled with specialized light sources and detectors to deliver non‐contact, continuous monitoring without the need for reagents or extensive sample handling. Its portable analyzers are designed for field use, allowing operators to verify process conditions on demand, while its OEM sensor modules can be integrated directly into customer equipment or skid packages. The company also offers technical support, calibration services and licensing agreements to facilitate adoption of its technologies. Founded in the Houston area, Coretec has focused on research and development to expand its intellectual property portfolio, securing multiple patents in optical sensing and instrumentation. Although the company maintains its headquarters in North America, it has partnered with representative firms and distributors in Europe and Asia to support global customers. Coretec’s licensing‐centric business model enables it to collaborate with original equipment manufacturers and system integrators, minimizing capital expenditure while broadening its market reach. Through ongoing innovation in fiber optic sensing and strategic partnerships with industrial end users, The Coretec Group aims to deliver advanced analytical solutions that help companies optimize processes, reduce waste and ensure product consistency. Its emphasis on non‐invasive, real‐time monitoring positions it as a specialist in applications where traditional sampling methods fall short, particularly in demanding chemical and energy sector environments.AI Generated.
