请教大家：色谱法是否已经工业化？

色铺技术当然了, "中石化","中石油",电力局等等都用它,

两种方法:
(1)换元法
令1/x=t,x=1/t
x/(1-x)=1/t/(1-1/t)=1/(t-1)
f(t)=1/(t-1)
f(x)=1/(x-1)

(2)替代法
f(1/x)=x/(1-x)
=1/(1/x-1)

所以
f(x)=1/(x-1)

yes, in separation and purification.

离子交换色谱 has been used to make pure water since over 40 years ago.

是的 测量 化工

Yes啦
