Some examples of separation of mixtures by using this method are as: Separation of benzene (boiling point 353 K) and toluene (boiling point 384 K). Separation of chlorobenzene and bromobenzene. You can also use this method of separation for separation and recovery of both components of a solid-liquid mixture.

Separation funnel method. When four different solvents (n-hexane, chloroform, acetone, and n-butanol) are selected, fractionation begins by moistening or complete dissolution of crude extract with 250mL of water. This is followed by transfer into a separating funnel, shaken, and allowed to settle.
Supercritical fluid chromatography (SFC) is a separation method that uses compressed gas above the critical temperature/pressure instead of organic solvent . SFC is a green separation technique that uses mostly supercritical carbon dioxide as the mobile phase, with the eluting power controlled by the addition of organic solvent as an organic ...
A method was developed for the separation of baicalin, baicalein, wogonin, and oroxylin A in Scutellariae radix by high-performance TLC on phenyldimethylethoxysilane-treated silica plates with methanol-phosphate buffer (pH 6.2) as mobile phase . Quantitative determination of the flavonoids was conducted with a dual-wavelength flying-spot ...
Separation methods. The components in the extract from above methods are complex and contain a variety of natural products that require further separation and purification to obtain the active fraction or pure natural products. The separation depends on the physical or chemical difference of the individual natural product.

Importance of Chiral Drug Separation In the early 1980s analytical chiral separation was a rather difficult task, and preparative synthetic and separation methods were not as advanced as today. Nevertheless, it was clear that chiral drugs should be enantioseparated and that each enantiomer should be used separately. Nowadays, enantiomers are

Separation anxiety is a serious condition, and it goes beyond the occasional mournful whimper when you leave the house or the shredded sock waiting for you upon your return.
Separation methods, then, can be defined as processes that change the relative amounts of substances in a mixture. In chemical methods, one may start with a completely homogeneous mixture (a solution) or a heterogeneous sample (e.g., solid plus liquid). In the act of separation, some particles are either partially or totally removed from the ...
