Ways of Separating mixtures

Y

evaporation and crystallisation

Crystallisation is the process of concentrating a solution to a supersaturated state to cause the formation of solid particles in a homogeneous phase.

Evaporation is the process of a liquid substance turning into its gaseous state.

Distillation

Distillation is a technique used to separate liquid (the solvent) from a mixture and keep the liquid part.

Decanting

Decanting is the process to separate mixtures, it uses sedimentation.

Sedimentation is the process of two substances to
separate due to gravity.

magnetic separation

When something is attracted to a magnet, this
substance usually contains iron.

Chromatography

Chromatography lets you separate and identify, the different compounds in a mixture you want to analyse.

Stereomicroscope (light)

reflected illumination rather than transmitted (diascopic) illumination, that is, light reflected from the surface of an object rather than light transmitted through an object.

Compound microscope (light)

Compound microscopes are used to view microorganisms or other objects too tiny to be seen with the naked eye. A light shines through the object and the two lenses magnify the size of the object.

It allows you to view live samples of specimen

What we use now?

Confocal laser scanning microscope

allows researchers to focus a laser beam to a specific depth within a tissue to analyze the concentration of components at that level.

Scanning electron microscope (SEM)

produces detailed, magnified images of an object by scanning its surface to create a high resolution image

CryoSEM

enables observation of bulk biological materials in hydrated conditions by conversion of liquid water to solid by cryofixation,

Electron tomography

allows the study of the 3D organization of thin individual cell organelles and bacterial cells at nanometer resolutions without slicing them

Transmission electron microscope (TEM)

Transmission electron microscopy (TEM) is an analytical technique used to visualize the smallest structures in matter.
