死体积本意是指色谱柱中未被固定相占据的空隙体积,也即色谱柱内流动相的体积。但在实际测量时,它包括了柱外死体积(色谱仪中的管路和连接头间的空间以及进样系统和检测器的空间)。当柱外体积很小时,可以忽略不计。
死体积(dead volume)() 指色谱柱中不被固定相占据的空间及色谱仪中管路和连接头间的空间以及检测器的空间的总和,等于死时间乘以载气的流速。3.

该计量系统也可以缓和计量系统中的死体积。
The metering system may also mitigate dead volume in the metering system.
不过,我还没有考虑对应这个过程的梯度范围和死体积。
However, I have not considered how the gradient range and dwell volume fit into the process.
结果表明死体积与流动相种类、配比和柱温等因素有关。
Experimental results further showed that dead volumes were also related to factors, such as the characteristics of the mobile phase, its composition and the column temperature.
