1. It utilizes Electronic Dump Control and electronic cam technology to control flow pulsation, effectively ensuring the accuracy and repeatability of the flow rate and guaranteeing low baseline noise; single stroke liquid volume is 30ul. Flow rate range: 0.0001–9.999 ml/min, increment 0.0001ml/min; maximum pressure resistance 62Mpa, flow rate accuracy ≤0.02%. Detection system: Deuterium lamp and tungsten lamp are installed simultaneously, allowing for automatic full-wavelength scanning and switching; dual-wavelength detection, wavelength time programming; wavelength range: 190nm–900nm, wavelength accuracy 0.1nm, spectral bandwidth 8nm. Gradient mixing precision: 0.1% or 1ul/min, gradient mixing repeatability: RSD = 0.1%, injection repeatability: RSD = 0.1%. Sensitivity: ≤2×10⁻¹⁰g/ml naphthalene methanol solution. Control workstation: The workstation can set and control all instrument parameters and the autosampler, automatically track all critical liquid chromatography parameters and alert the user when interference and errors occur, providing online guidance for automatic system detection and facilitating maintenance; it has three-level management and audit trail functions, fully complying with CFDA GxP and FDA 21CFR-Part11 requirements; it outputs proportional chromatograms during dual-wavelength measurement, and uses a built-in algorithm to determine component content;

2. Long seal ring lifespan, multi-point flow calibration curve, ensuring flow accuracy across the entire flow range;

3. Plunger suspension drive technology design ensures a long lifespan for the high-pressure seal ring. It adopts a dual-plunger parallel pump structure with alternating liquid delivery from two pump heads. 1. Under the same infusion volume, the lifespan of the piston rod and sealing ring is twice as long as that of a series pump;

4. The automatic plunger cleaning function cleans the plunger and the back of the plunger sealing ring, preventing the shortening of the sealing ring's lifespan due to crystallization of high-salt concentration buffer solutions;

5. GLP function: Pressure curve, flow rate curve, and recording of the number of uses of the plunger rod sealing ring. Pressure pulsation: ≤ 0.1%, maximum pressure resistance: ≤ 45 Mpa (ASI pump head);

6. Dual-beam optical system enables dual-wavelength detection;

7. The monochromator uses high-precision control to improve wavelength accuracy;

8. Brand new automatic wavelength calibration. Wavelength accuracy: 0.1nm, wavelength repeatability: 0.1nm. Noise: ≤ 0.25 × 10⁻⁵ AU. Drift: ≤ 0.5 × 10⁻⁴ AU. Flow cell volume: 10ul;

9. Multi-mode wavelength scanning: 3 scanning modes, programmable wavelength;

10. LCD screen displays all parameters, which can be set through the instrument itself or through the control workstation. 99 user programs, enabling flow rate, gradient, and wavelength programming;

11. Third-party software interface: Open-source computer control communication protocol, facilitating control by third-party software.
