Description
  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

For other cost/time saving measures consider:

  • LEAP offers multiple choices of Valve Self Wash Stations to aid in cleaning the valve [14]
  • LEAP Shell Software and application for custom injections and scheduling [15]
