Natural Gas Station Gas Quality Detector

Natural Gas Station Gas Quality Detector

With continuous technological advancements and innovations, the performance will continue to improve, injecting new vitality into the green development of the natural gas industry. Let us look forward to more remarkable performances of this "magic tool" in the future energy sector!

Gas Chromatograph plays a crucial role in the detection of natural gas calorific value. Through the separation of components by the chromatographic column, detection by the thermal conductivity detector, and the data analysis capabilities of the calorific value version chromatographic workstation, we can obtain the content and calorific value information of each component in natural gas, providing a scientific basis for the rational utilization and combustion control of natural gas.

Natural Gas Station Gas Quality Detector

Main Technical Specifications:

● The machine adopts a modular design, with a compact and rational body structure, offering multiple expansion functions and ensuring accurate and rapid analysis.

● Equipped with a 5.7-inch LCD screen, displaying rich and intuitive content, making human-machine interaction simpler. Supports both Chinese and English language modes to meet the needs of different customers.

● Utilizes an advanced microcomputer control system, enabling all control and analysis tasks to be completed on a PC. Alternatively, an optional built-in AD conversion circuit allows direct digital output of chromatographic signals.

● Features 6 control modules, each with temperature control ranging from room temperature to 400°C, adjustable in increments of 1°C, with an accuracy of ±0.1°C.

● Includes over-temperature protection; if any temperature control system exceeds the set protection value, it automatically cuts off power to prevent hazards caused by temperature loss of control.

● Intelligent flexible rear door design for more precise temperature control accuracy.

● Supports 9-stage programmed temperature rise to meet the needs of complex sample analysis.

● Temperature rise rate: 0.1～40°C/min

● Multiple injection methods available: on-column injection, split/splitless injection, packed column injection, gas valve injection, headspace injection, thermal desorption injection, purge and trap injection, flash evaporation injection, etc.

● 20L large column oven, laying the foundation for multidimensional chromatographic analysis.

● External control event module, capable of being equipped with a multi-valve, multi-column switching system, enabling complete analysis of complex gas components with a single injection. Achieves automated instrument operation.

● Supports installation of up to 3 detectors (FID, TCD, ECD, FPD, NPD) as optional, and can also install a methane converter.

●Injection initiation: manual or automatic optional; when automatic injection is selected, it can simultaneously initiate the programmed temperature rise function.
