Korei Chromatography showcases at the 2026 Xinjiang Petroleum and Chemical Industry Expo, leveraging its independently developed, controllable chromatography technology to support domestic substitution in the energy and chemical sectors.
From September 3 to 5, the 2026 Xinjiang Petroleum and Chemical Industry Expo concluded successfully in Urumqi. Kairui Chromatography showcased its domestically produced high-end gas chromatograph, specifically designed for the harsh and complex operating conditions of the coal‑chemical industry. With its robust technical expertise and a clear positioning as a “production‑oriented service provider,” the company garnered significant attention from numerous major state‑owned enterprises.
Major state-owned enterprises are paying close attention, and domestic substitution is imperative.
During the exhibition, Corry’s booth drew technical experts and procurement managers from numerous major state-owned enterprises. After gaining a thorough understanding of Corry Instruments’ technical specifications, application case studies, and service framework, many representatives from these state-owned companies expressed strong interest in collaboration.
“Many of our key instruments still rely on imported chromatographs, resulting in long procurement lead times and slow after-sales response. Kairui’s instruments have already met the required standards in terms of stability and operational robustness, making domestic substitution an inevitable trend.”
Representatives from Sinopec’s refining and petrochemical enterprises expressed keen interest in Corry’s sulfide detection technology: “Sulfide detection in natural gas and refinery gas has long been a challenging task; Core can achieve levels below 5 ppb, fully capable of replacing imported products.”
These pieces of feedback have further strengthened the Core team’s resolve. The strategic direction of “leveraging independently controllable chromatography technology to support domestic substitution in the energy and chemical industries.”
Built for the harsh operating conditions of the coal chemical industry: rugged and durable, precise and reliable.
The coal‑chemical industry operates under harsh conditions—high temperature, high pressure, high dust levels, corrosive gases, and continuous operation—placing extremely stringent demands on chromatograph stability. The domestically produced high‑end gas chromatograph showcased by Core is specifically engineered to address these challenges:
Durable and reliable: designed lifespan 10–15 years: injector valve life > 1 million cycles; detector life > 10 years.
Ultra-stable: Overall integrity rate > 99%, with annual downtime of less than 19 hours.
Precision Testing: Repeatability RSD ≤ 0.5%; detection limits for H₂S and COS < 5 ppb; CO: 0.046 ppm; CO₂: 0.34 ppm.
Explosion-proof option: An explosion-proof online chromatograph is available for hazardous operating environments. 24-hour continuous monitoring
A production-oriented service provider centered on chromatographic technology.
Kerry is different from Manufacturer Rather than a mere integrator, we are a production‑oriented service provider centered on chromatography technology. From core component R&D to complete instrument manufacturing, and from method development to after‑sales support, we ensure end-to-end independent control across the entire value chain.
The production base is located in the Liaoning (Dandong) Instrument and Meter Industry Park, making it one of China’s largest gas chromatography manufacturers with a significant cost advantage. After-sales engineers are stationed nationwide, and upon receipt of a work order… We arrive on-site within 24 hours; simply scan the QR code to submit a service request—no need for cumbersome phone transfers.
Firmly Pursuing the Path of Domestic Substitution
Xinjiang is a major hub for China’s energy and chemical industries, as well as a strategic foothold for the domestic substitution of imported instruments. Taking this exhibition as an opportunity, Core Chromatography will continue to deepen its expertise in coal chemistry, petroleum and petrochemicals, natural gas, and other sectors, leveraging independently developed, fully controllable chromatographic technologies to provide large state-owned enterprises and industry clients with robust, durable, highly accurate, and reliably performing high-end domestically produced analytical instruments, backed by timely and responsive service.
Leveraging independently controllable chromatography technology to support domestic substitution in the energy and chemical industries. — Corei Chromatography, on the road.
