The gas chromatography is special type of chromatography, where the mobile phase is gas, such as helium or nitrogen. The stationary phase is usually solid support covered with liquid layer. After the sample injection the mobile phase carries the sample compounds through the column. Usually, the temperature gradient is applied and compounds are then separated [...]
Chromatography is analytical chemistry method which is used (and useful) for the separation of complex mixtures of chemical compounds. The main mechanism of the separation is repeatable distribution of the tested compound in between two different phases. Usually, one phase is solid, fixed in the separation device and the other is moving and flows through [...]
