主要规格及技术指标

1. Wide Range of Liquid Delivery Flow Rates, Covering Semi-Microanalysis to Semi-Preparative
The liquid delivery flow rate range is extensive, allowing for selections from 0.001 to 20.00 mL/min. Due to the adoption of a parallel dual-plunger reciprocating pump drive system, even at low flow rates, it can ensure low pulsation and stable flow.
2. Cyclic Preparative Function
By installing an optional set of circulation components and circulation valves, closed-loop cyclic preparative separation can be achieved. The optimized design of the pump head with a minimal volume can reduce column external diffusion effects and improve cycling efficiency.
3.UV Detector:
It incorporates a built-in low-pressure mercury lamp for wavelength calibration and correction. The calibration is performed automatically during startup, and manual correction can be conducted at any time. It features the capability of simultaneous dual-wavelength determination.
Light Source: Deuterium lamp.
Wavelength Range: 190 – 700 nm.
Wavelength Accuracy: ±1 nm
Wavelength Precision: ±0.1 nm
4.Baseline Noise: Less than ±0.25 × 10⁻⁵ AU (measured at 250 nm, with constant room temperature and isopropanol in the flow cell), complying with ASTM standards.
Drift: Less than 1 × 10⁻⁴ AU/h;
Measurement Range: 2.5 AU
1.送液流速范围大，涵盖半微量分析到半制备
送液流速范围大，可在0.001-20.00mL/min 的范围内选择。由于采用了的并联双柱塞循环泵驱动方式，即使是低流速时也能确保较低脉动和稳定的流量,流速精确度0.1%RSD, 准确度 1%；
2. 循环制备功能
通过安装一套选配的循环组件和循环阀，可实现闭合环路循环制备分离。经过优化设计的泵头容积极小，可减少柱外扩散效应并提高循环效率；
