Introduction
The thin layer chromatography (TLC) is a kind of chromatography where the stationary phase is a thin layer of material deposited on a support, this set is called a plate. The mobile phase is a solvent mixture, call eluent, that it moves for the stationary phase by means of capillarity. Generally, the plates are formed […]

He’s famous “for his work in the equation of state of gases and the liquids”, for which he obtain the Nobel prize of Physics in 1910.
Van der Waals was the first one in realizing the need to take in consideration the volume of the molecules and the intermolecular forces establishing the relation among pressure, volume […]

The instrumental methods are based on the measurement of some physicist-chemistry property. Its use has increased with the development of the electronics, for the facility of detecting changes in the physicist-chemistry properties and transform them to an understandable language for the humans. An analytical instrument is the support in which is developed this transformation.

When we face a problem in analytical chemistry, habitually, we must use a few patron to realize a calibrated straight line and this way find the concentration estimated of the sample problem.
The information must appear with a bit of rigor and all the results will have to go accompanied of its error. These errors always […]
