How Chromatography Is Used In The Lab Environment By: Andrew Long | - Chromatography, with its humble beginnings, has been developed into a high-tech analytical tool. In the early Twentieth Century, plant pigments were separated using a technique of dipping columns of Calcium Carbonate, from limestone, into ground plant and the resulting juices. The non-pigmented liquid would travel up the columns, dragging the pigments behind. The density of the pigment would factor how the separation worked, thus different pigments in the plant, such as Chlorophyll, would sto ...

Hplc Methods Explained In The Laboratory By: Andrew Long | - High-performance liquid chromatography (HPLC method) is a powerful type of column chromatography. Rather than allowing a solvent to drip through the column using only gravity, it is forced through the column using pressures of as much as 400 atmospheres.
This makes it significantly faster than standard column chromatography and also allows for the use of column packing material which has a much smaller particle size. This in turn provides a much greater surface area for inter ... Tags:hplc, liquid chromatography, lab instruments, lab suppliers
Chromatography refers to a set of laboratory methods and techniques for the separation of mixtures. It involves passing a mixture that dissolved in a mobile phase through a medium known as the stationary phase. This separates the analyte to be measured from other components of the mixture and allows it to be isolated.
