SP-5220 Gas Chromatograph has passed five professional certifications, confirming that the instrument is capable of safe, stable, and trouble-free operation for an average of 5,000+ hours.

Based on the new generation of high-precision EPC system, high stability temperature control system. Ensure that the instrument generates fast, accurate and reliable data.

The new generation of high-precision EPC has, a pressure control accuracy of up to 0.001 psi; EPC adopts high-precision pressure and flow sensors, high-precision amplified data acquisition and control circuits, thus realizing high-precision pressure and flow control, with a control accuracy up to 0.001 psi, in order to ensure excellent qualitative and quantitative repeatability. At the same time, the adoption of atmospheric pressure and room temperature compensation technology can ensure that the pressure control accuracy in the external conditions change can still obtain excellent control performance.

The high-speed closed-loop temperature control system makes the temperature control accuracy reach 0.1℃, and the program temperature rise repeatability reaches 0.5%, Through the theoretical modeling of the column box and the physical prototype verification, it ensures the excellent column box structure system. A reasonable column box structure better realizes the internal heat conduction of the system and can realize up to 120 ℃ / min heating rate. Self-developed high-speed closed-loop temperature control system, as well as complex environment based on the heating power, after the opening of the door, fan speed, and other parameters of the mathematical control model, the adoption of the AC power supply over-zero detection circuit to achieve accurate heating power control, thus ensuring high-precision temperature control and the repeatability of the temperature control for a number of times.

The new intelligent electrical control system developed based on Linux system can realize multi-terminal status monitoring and Internet remote control to meet the demands of users for more application scenarios.
