In the field of gas chromatography (GC/GC-MS) analysis, the accuracy of gas sample injection directly determines the reliability of detection results. Traditional samplers cause condensation of sample moisture due to temperature fluctuations

Unstable pressure can cause injection volume deviation, especially in the analysis scenarios of trace components (such as ppb level VOCs) and high-purity gases (such as 99.999% high-purity nitrogen), where the error problem is more prominent. Regarding this industry

The pain point of the industry is that Ruike Tongheng has been commissioned by customers to design a temperature pressure linkage intelligent gas injection controller, which has emerged with the core technology of "synchronous temperature control+precise voltage stabilization", bringing a revolution to the field of analysis and detection

Sexual solutions.

Innovative Technology: Deep Collaboration between Synchronous Temperature Control and Precise Voltage Stabilization

The controller achieves intelligent switching of gas paths through the combination of electric sequential selection valve (XT-D type), manual switching valve (QH-S type), and stabilizing valve (WY-SL-1 type), ensuring temperature fluctuation control of the injected gas

Within the range of ± 0.5 ℃, the sample moisture does not condense, and the pressure control detection is accurate. When the temperature drops and the moisture exceeds the threshold, the program automatically switches the gas path to stabilize the backend gas state. The controller is adaptable

5MPa pressure input and 300 ℃ high temperature environment (Ruike Tongheng 330 ℃ high temperature valve), can be directly connected to the input gas source to meet the requirements of complex working conditions.

Intelligent Algorithm: The entire process is controllable, solving the three major pain points of traditional devices

Through the intelligent PID temperature control algorithm, the controller can eliminate temperature error interference and accurately control the moisture content in the injected gas. Based on the set temperature and pressure signal threshold, intelligently switch the valve group to control the injection gas path,

Realize full process controllability. This design solves the three major pain points of traditional equipment, including poor repeatability, strong manual dependence, and difficulty in adapting to complex working conditions. It breaks through the limitations of traditional "decentralized" design and combines temperature control with

Deep coordination of pressure regulation ensures that the sample remains stable throughout the entire injection process.

【 Application prospects 】: Promote trace analysis and high-purity gas detection to new heights

The emergence of temperature pressure linkage intelligent gas injection controller provides more reliable technical support for the analysis of trace components (such as ppb level VOCs) and high-purity gases (such as 99.999% high-purity nitrogen). Its precision

The ability to control temperature and stabilize voltage is expected to play an important role in environmental monitoring, food safety, drug research and development, and promote gas chromatography analysis technology to a new stage of higher accuracy and efficiency.

【 Conclusion 】
