# HPLC Column

An HPLC column of length 15cm and ID of 4.6mm is tightly packed with monodisperse ODS particles of diameter 3:m surface area 300m/g^2 and density 1.2g/mL. Dead volume is 1.2mL. Assuming that the particles are tightly packed and that the void volume is essentially due to the pore volumes of the particles, calculate:

1. the # of ODS particles in the column

2. the weight in grams of the ODS needed to obtain a

tight packing

3. the mass ingrams of each ODS particle

4. the pore volume of each ODS particle

#### Solution Preview

First, we need to calculate the volume of the column. The volume of a cylinder is given as pi*r^2*h = 3.141 * (2.3)^2 * 150 = 2492.38 square mm or 24.92 mL. Since we are to assume in this question that the dead volume is made up completely ...
