| Multiple Valve Applications for LC |
| Code | Application | Control SW | Key Hardware | Key Benefits | Restrictions | GLP |
|---|---|---|---|---|---|---|
| M-001 [1] | Dual Channel Serial Injection Provides shorter cycle times by regenerating columns during next analytical run | Analyst with ICC-CE | * 6 port injection valve * 10 port Valve * Gradient Pump * Regeneration pump | * Saving of regeneration time(Back Cut) * Increase throughput at little cost * Control is all within Analyst * Compliance is not affected | * Can not do "Look Ahead" * Injections are not staggered * Peaks of interest must come of early * Columns may perform slightly differently on alternating samples | Yes |
| Code | Application | Control SW | Key Hardware | Key Benefits | Restrictions | GLP |
|---|---|---|---|---|---|---|
| M-002 [2] | Dual Channel Serial Injection with Front Cut Provides shorter cycle times by regenerating columns during next analytical run and diverts the solvent front to waste | Analyst with ICC-CE | * Trio VS * Gradient Pump * Regeneration pump | * Saving of regeneration time(Back Cut) * Increase throughput at little cost * Control is all within Analyst * Compliance is not affected * Avoids contaminating MS inlet with early eluting compounds and solvent | * Can not do "Look Ahead" * Injections are not staggered * Peaks of interest must come of early * Columns may perform slightly differently on alternating samples | Yes |
| Code | Application | Control SW | Key Hardware | Key Benefits | Restrictions | GLP |
|---|---|---|---|---|---|---|
| M-003 [3] | Dual Channel Parallel Injection Provides shorter cycle times by limiting the acquisition time to just the peaks of interest and regenerating columns during acquisition | Cycle Composer outside of Analyst | * DoubleStack valve * 6 port injection valve * FWS in front of 6 port valve * Gradient Pump * Regeneration pump | * Saving of Front and Back Cut * Provides "Look Ahead" * Provides staggering of injections | * Requires matching sample lists in Cycle Composer and Analyst * Columns may perform slightly differently on alternating samples | No |
| Code | Application | Control SW | Key Hardware | Key Benefits | Restrictions | GLP |
|---|---|---|---|---|---|---|
| M-004 [4] | Analyst with "Look Ahead" with LEAP Shell Control of the Sample List is through LEAP Shell | LEAP Shell | * Standard PAL * Pumps are supported within Analyst | * "Look Ahead" * Can import custom columns * Freedom to create and use custom Cycles | * Does not support 21CFR11 compliance | No |
| Code | Application | Control SW | Key Hardware | Key Benefits | Restrictions | GLP |
|---|---|---|---|---|---|---|
| M-005 [5] | Dual Channel Parallel Injection Provides minimum cycle times by limiting the acquisition time to just the peaks of interest and regenerating columns during acquisition | LEAP Shell | * DoubleStack valve * 6 port injection valve * FWS in front of 6 port valve * Gradient Pump * Regeneration pump | * Integration with Analyst Software * Single Sample List * Provides staggering of injections * Multiplexes 2 separate LC systems into on MS | * Does not support 21CFR11 compliance * Requires pumps to be integrated with LEAP Shell | No |
| Code | Application | Control SW | Key Hardware | Key Benefits | Restrictions | GLP |
|---|---|---|---|---|---|---|
| M-006 [6] | Inline Sample Concentration SPE Column regenerated during analytical extraction | Analyst with ICC-CE | * TrioVS | * Automated concentration and elution of sample on SPE column prior to separation on analytical column | * No "Look Ahead" * Can not prep samples ahead of analytical run | No |
| Code | Application | Control SW | Key Hardware | Key Benefits | Restrictions | GLP |
|---|---|---|---|---|---|---|

For other cost/time saving measures consider:
- LEAP offers multiple choices of Valve Self Wash Stations to aid in cleaning the valve [15]
- LEAP offers custom sample prep and inject with Analyst and other data systems
- LEAP Shell Software and application for custom injections and scheduling [16]
