refer to the column instruction manual. If adequate results cannot be achieved after rinsing, columns can sometimes be backflushed. (Rinse solution is pumped in the opposite direction at a low flowrate through the column, from the column outlet end.) However, be sure to check the ...
8、Flow rate (GC):流速可以最大在±50%调整。(备注:如果专论中规定了线性速度参数,如果载气系统可以按设置的控制,线性速度可以在 +50%~ −25%范围内调整) 9、Flow rate (HPLC):当粒度改变时,流速也许需要调整,因为为达到相同的性能,小粒度的柱子需要更高的线...

Low-flow chromatography is ideal when detailed sample information is required from small sample volumes, such as in omics research. Compared with analytical flow (>100 µL/min), low-flow LC-MS (<100 µL/min) typically provides a large increase in sensitivity. Low-flo...
等度分析:按“direct”设定A、B、C、D流动相的百分比,直接输入“flow rate”(0.8-1.5ml/min),按Enter 即可。 梯度分析:按“program method”, 编辑梯度洗脱的程序,按“save”,保存到“program table”(1-15)中,按“operate method”, 输入你在“program table”中所保留的数字(1-15),再按“operate method...
In a high performance liquid chromatography system, wherein a mobile phase is driven through a stationary phase for separating compounds of a sample fluid comprised in the mobile phase, a flow rate of the mobile phase is controlled in dependence on a variation in a control value in the system...
13,V/V)at a flow rate of 1 ml/min,the detection wavelength was 230 nm,the column temperature was 25 ℃ and the injection volume was 10 μ l. Quantitative analysis was conducted for the processes and procedures and the uncertainty was evaluated. RESULTS:The linear range of paeoniflorin ...
