Description:

CAMAG AMD2 System comprised of chromatogram developing module, standard accessories and represents High Performance Thin-Layer Chromatography, TLC / HPTLC. TLC/HPTLC differs from all other chromatographic techniques in the fact that in addition to stationary and mobile phases, a gas phase is present, which can significantly influence the result of the separation. The CAMAG Automated Multiple Development procedure allows High-Performance Thin-Layer Chromatography to be utilized for difficult analytical tasks that cannot be solved by isocratic HPTLC and could not be performed by TLC in the past.
Only the AMD 2 procedure can be successfully employed for reproducible gradient elution with silica gel as the stationary phase. In column liquid chromatography, gradient elution is common on reversed-phases only because a silica gel column would call for a time consuming reconditioning or be irreversibly degraded, which is not acceptable in a technique depending on multiple use of the stationary phase. In High-Performance Thin-Layer Chromatography this is not relevant.
The principle of the CAMAG AMD procedure:
- The HPTLC plate is developed repeatedly in the same direction.
- Each successive run extends over a longer solvent migration distance than the one before.
- Between runs, the solvent is completely removed from the developing chamber and the layer is dried under vacuum.
- Each successive run uses a solvent of lower elution strength than that of the one used before. In this way, a stepwise elution gradient is formed.
- The combination of focusing effect and gradient elution results in extremely narrow bands. Their typical peak width is about 1 mm. This means that, within the available separation distance of 80 mm, up to 40 components can be completely resolved, i.e. with base line separation.
The AMD 2, like other computer controlled CAMAG instruments, communicates with winCATS. The gradient, made from up to 5 solvent bottles, is defined by input into a table in winCATS. Gradient and developing distance for each run are graphically displayed for verification. All individual runs of the developing program are performed fully automatic and monitored by winCATS.
The AMD 2 system is to be operated with an óil-sealed rotary vane vacuum pump RV3 (Edwards), including gas ballast/oil return, oil vapor filter, flexible vacuum hose 1 m, ready to connect to the CAMAG AMD 2 System.
