(I suppose that you mean supercritical state of fluid.)

Supercritical state of liquid-gas is a state that liquid state and gas state stop to exist at particular temperature and pressure.

There is only just fluid state which has both liquid and gas property and if you change the pressure or temperature just a bit, it will change to one of the state.

How to achieve supercritical state ?

The supercritical state is done at HIGH TEMPERATURE and PRESSURE.

For example, the famous CO2 fluid (used to separate caffeine from the coffee bean) is acquired at 304.1 Kelvin and 72.8 atm.

Why does Jupiter have no surface?

Jupiter is a gas planet made mostly of hydrogen and helium. The outer layer is simply made of gas. As depth increases, so do pressure and temperature. Deeper within the planet the gas gradually transitions into a supercritical fluid, a state of matter that is in between liquid and gas. Even deeper this supercritical fluid transitions into an exotic state of matter known as metallic hydrogen. It is currently unclear if this form of matter behaves as a liquid or a solid.

What is supercritical fluid chromatography?

Supercritical fluid chromatography is very similar to high pressure liquid chromatography (HPLC), however the mobile phase exists in a supercritical state. To refresh your memory, recall that super critical fluids exist at temperatures and pressures higher than a substances critical point. This means that the fluid acts as both a gas and a liquid. For example, a supercritical fluid may pass through substances like a gas, but also dissolve substances like a liquid. Why do supercritical fluids exist? Well, the temperature is high enough that the molecules cannot exist together as a fluid because they have too much energy to stick together. However, the pressure is too high for the molecules to have a root mean square distance sufficient enough to exist as a gas. SFC exploits this property, using a supercritical fluid to dissolve the chemical in question into the fluid, but move it quickly in the gas phase. Heavy molecules travel slower, while light molecules travel faster, thus causing separation. In addition, chiral molecules can be separated via this method.

What type of solvent is carbon dioxide?

Liquid carbon dioxide (supercritical CO2) is used as solvent.

Is Jupiter mostly liquid?

Largely. Jupiter's outer portion is gas, but much of the interior is a supercritical fluid, a state of matter that is neither liquid nor gas, but has some characteristics of both. Deeper into the interior there is probably yet another state of matter; liquid metallic hydrogen.

Why is nitrogen not used in supercritical fluid extraction?

Because at room temperature it behaves like gas. Although it is in supercritical state, its density becomes very low on temperatures far above critical value, so it behaves like gas and it's not useful for extraction.
