Description | |
LC Column Switching & Regeneration. |
Contents |
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 using a Standard 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 valve for column switching.
Both valves must be controlled by the Standard LEAP cycle. LEAP can not control the MS Selector valve as part of the cycle.
Key Benefits |
Saving of Reagent time (Back cut) |

Control is all within Analyst |
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 |

For other cost/time saving measures consider:
- LEAP offers multiple choices of Valve Self Wash Stations to aid in cleaning the valve [1]
- Dual Channel Serial Injection with Front Cut (M-002) using Analyst and ICC-CE [2]
- Dual Channel Parallel Injection (M-003) using Cycle Composer Software and Analyst [3]
- “Look Ahead”, sample prep before injection (M-004) using LEAP Shell Software [4]
- Dual Channel Parallel Injection (M-005) using LEAP Shell software [5]
- LEAP Shell Software and application for custom injections and scheduling [6]
