Problem $1\mathrm{.}2$:

You are a research engineer. You need to frequently measure the molecular weight of the polymer synthesized by the synthesis group. Hence, you find it will be beneficial to have a molecular weight measuring tool in your research lab. You came to know two tools available $($osmometry and GPC$).$ However, you do not know which one is suitable for you. Your department head is requesting you to compare both techniques, operation principles, and pros$-$cons and finally recommend the one that you want to buy.
