High performance liquid chromatography is used to separate non volatile compounds
Uranium is a non-volatile solid metal.
DRAM is volatile.
gas chromatographt (GC) and High Performance Liquid Chromatography (HPLC) are different , and to understand why you must think about what chromatography is: Chromatography in its simplest form is like putting ink on blotting paper and watching the colours separate. Liquid chromatoraphy uses a "column" which is made from bare or bonded silica, it separates a mixture of compounds by how polar they are. You can use a gradient of different solvents. GC also uses a column, but it is a capillary column and instead of using a liquid to carry your mixture which needs to be separated it uses a carrier gas, like nitrogen. You can vary the temperatures in both LC and GC to aid better resolution. GC is used for more volatile compounds and LC is used more less volatile. HPLC usually refers to reversed phase, normal phase is where the column is vare silica which is very polar. Bonded silica is bonded with hydrocarbons which is non polar. The thing to remember is that "like attracts like" so if the column in non polar, the compound to elute first will be the most polar. To summarise, they are both separation techniques, one uses gas and the other liquid. You would choose which one to uese depending on how volatile the compounds which you want to separate are.

Uranium is a metal, non-volatile; neon is a gas.
A volatile liquid evaporates easily and so requires lesser temperature. A non-volatile liquid requires more temperature to evaporate
In chemistry, we use the term volatile to speak to the ability of a substance to become a vapor, or to vaporize. There are many non-volatile compounds. Common table salt, NaCl, won't be encountered as a vapor in any "normal" situation. You can't even get salt to vaporize in a kitchen oven set on high. There are many, many other non-volatile compounds about.
Yes, all the salts are ionic compounds and ionic compound can neither be volatile.
