Column chromatography is commonly used to separate non-volatile compounds based on their interactions with the stationary phase within the column. The compounds are separated as they travel at different rates through the column due to varying affinities to the stationary phase.

What kind of species can be separated by high performance liquid chromatography but not gas chromatography?
Polar and non-volatile compounds, such as large biomolecules like proteins or carbohydrates, can be separated by high performance liquid chromatography but not gas chromatography due to differences in their chemical properties and interaction with the stationary phase. Gas chromatography is more suitable for separating volatile and non-polar compounds based on their volatility and interaction with the stationary phase.
Which of the compounds elute fast in reverse phase chromatography?
Compounds that are non-polar elute faster in reverse phase chromatography as the stationary phase is non-polar and retains polar compounds longer. Polarity of the compound determines its retention time in reverse phase chromatography.
How Chromatography can be used for non colored solution?
Chromatography can still separate components in a non-colored solution based on their different chemical properties such as size, polarity, or charge. For example, in gas chromatography, compounds can be separated based on their boiling points and in size exclusion chromatography, molecules are separated by size. By utilizing these principles, chromatography can successfully separate and analyze components of non-colored solutions.
Why column chromatography doesn't separate polar compounds?
Column chromatography is more effective at separating non-polar compounds because polar compounds have a stronger interaction with the stationary phase, leading to less effective separation. In contrast, non-polar compounds interact less with the stationary phase and therefore move more easily through the column, resulting in better separation in column chromatography.
What is non volitile solute?
A non-volatile solute is a substance that does not easily vaporize at normal temperatures and pressures. Non-volatile solutes increase the boiling point and decrease the vapor pressure of a solvent when dissolved in it. Common examples include salts, sugar, and various organic compounds.

What is a volatile an a non volatile?
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.
IS FLASH NON VOLATILE OR NON VOLATILE?
Non-volatile

What is difference between gc and hplc?
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.

What is normal and reverse chromatography?
Normal-phase chromatography separates molecules based on their polarities, with the stationary phase being polar and the mobile phase being nonpolar. Reverse-phase chromatography is the opposite, with a nonpolar stationary phase and a polar mobile phase. These techniques are commonly used in analytical chemistry to separate and analyze different compounds in a sample.
Is Rom is volatile or non volatile?
ROM is non-volatile memory.
Advantages and disadvantages of reverse phase liquid chromatography?
Advantages of reverse phase liquid chromatography include high resolution, wide applicability to various compounds, and good sensitivity. However, it can be time-consuming due to long run times, and non-polar compounds may not separate well.
What is a volatile and non volatile solute?
volatile will evaporate
