Agilent 1290 Infinity 二元泵(G4220A) 和VL 型二元泵(G4220B)
介紹：
安捷倫 1290 Infinity 二元泵具有業界最寬的分析能力范圍，具有最高的色譜性能和靈活性。延遲體積最低，在應用窄內徑柱時，可以實現超快速梯度的運行。主動阻尼與嵌入式固件的創新性泵(嵌入固件式算法調節驅動的創新型泵)設計相結合，大大降低了“泵波動”和相應的UV噪音。安捷倫 Jet Weaver 混合器采用了微流控混合技術，進一步降低了背景噪音。新型的陶瓷材質的柱塞桿，具有出色的熱穩定性，即使在高壓下也有耐用和可靠的性能。集成的高效率脫氣機和自動沖洗閥，使系統操作更方便。
無限的能力范圍結合了超高壓（最高 1200 bar）和高流速（最高 5 mL/min），具有最高的色譜性能、兼容性、靈活性和具有投資保護
在窄內徑柱上運行超快速梯度時的最低延遲體積（10 µL），使其完全適合作為 LC/MS 應用的前端
獨立控制的高分辨率泵驅動的主動阻尼和嵌入式固件的創新性泵設計相結合，大大降低了“泵波動”和相應的UV噪音
全新的安捷倫 Jet Weaver 混合器，采用了多層微流控技術，有利于達到最高混合效率，加上最低延遲體積，實現了最高 UV 檢測靈敏度
新型的陶瓷材質的柱塞桿，具有出色的熱穩定性，即使在高壓下也有耐用和可靠的性能
微量滲漏時可以自動補償，使儀器的正常運行時間更長
平滑運動控制，使得最高性能的二元泵也成為最安靜的泵
集成的、高效率的脫氣機（低死體積），采用了 Teflon AF 技術，能快速更換溶劑，以沖洗并啟動泵
提供最高進樣精度和最低交叉污染的快速進樣
