LC Gradient System VLIncludes gradient pump (max. pressure 400 bar) with integrated degasser, manual injector and variable wavelength detector with standard flow cell.
用两个特制的玻璃容器及一台平流泵即可实现二元线性梯度洗提。
Dual linear gradient elution can be performed with two specially made glass container and a high pressure constant flow pump.
低比转速泵的高扬程决定了叶片流道内逆压梯度比较高，这种压力分布使得水流易于在叶片表面脱流分离，这一现象甚至在泵的设计点也难以避免。
The high head produced by the impeller means high adverse pressure gradient within blade passage and because of this the flow often separates from the blade surfaces even at the design point.
