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 		* 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

M-014
[11] 		Selectable HPLC

(max 2 Streams) 		Analyst Standard Cycles * Two Injection Valves
* MS Stream Selector 		* Different Analyst Methods inject into different LC Valves
* Uses Standard Analyst cycles 		* Requires Analyst control of the stream selector valve
* Max of 2 streams can be supported 		No


Code Application Control SW Key Hardware Key Benefits Restrictions GLP
M-015
[12] 		Selectable HPLC

(max 4 Streams) 		Analyst with ICC-CE * Multiple Injection Valves (serial control)
* PAL 10 port Valve for Stream Selector 		* Different Analyst Methods inject into different LC Valves
* Stream selection to MS 		* PAL controls the stream selector valve
* Requires Custom Cycle 		No

For other cost/time saving measures consider:

  • LEAP offers multiple choices of Valve Self Wash Stations to aid in cleaning the valve [13]
  • LEAP Shell Software and application for custom injections and scheduling [14]
