Overview
This configuration allows the regeneration of one of the analytical columns while the other one is engaged - giving greater efficiency and higher throughput. This is run directly from within Analyst® Software from Applied Biosystems Inc® using a LEAP Cycle (requires ICC-CE software).
There are 2 pumps needed, one for the gradient run and another (higher flow rate and isocratic) for regeneration. This configuration requires a 6 port valve for sample loading and a 10 port valvefor column switching. Both valves must be controlled by the LEAP cycle.
Please note: LEAP can not control the MS Selector valve as part of the cycle.
| Key Benefits |
| Saving of Reagent time (Back cut) |
| Increase throughput at little cost |
| Control is all within Analyst Software |
| Compliance not affected |
| GLP Compliant |
| Restrictions |
| Cannot do "Look Ahead" |
| Injections are not staggered |
| Peaks of interest must come off early |
| Columns may perform slightly different on alternating samples |

Typical System of PAL with CoolStack Fast Wash and Valves
When columns must be regenerated following each analysis, this technique permits automation of the process. While one column performs the analysis, the second column undergoes regeneration by use of an auxiliary pump. Once the first analysis is complete, the valve is switched and the regenerated column is now ready for analytical use.
