Principles of Operation
The Total-Rapid-Prep™ performs complete sample preparation for
six samples for GC or GC/MS analysis in a few hours. This is achieved
by the simultaneous processing of six samples.
| a) | Solid or semi solid sample is mixed with drying agent and placed in the extraction cells. The extraction cells are then filled with the solvent(s) of choice. They are pressurized & heated. |
| b) | While the samples are being extracted the clean up columns are conditioned. |
| c) | As soon as the extraction cycle is terminated, the extraction columns are depressurized, and flushed with solvent, and then purged with nitrogen. |
| d) | At the moment of extraction columns depressurization the concentration cycle is started. |
| e) | Solvent exchange (if necessary) is performed for the concentrated sample, and the sample is then transferred to the clean up columns for purification. |
| f) | As soon as the first fractions start to come off the clean up columns, the concentration cycle starts. |
| g) | The final concentrated fractions are then transferred for GC/MS analysis. |
