| High Throughput LC injections alternating onto two analytical columns. |
Control Options
- Analyst Cycles (with ICC-CE) - NOT POSSIBLE Analyst does not support "Look-Ahead"
- Cycle Composer - Supports this application with custom macros outside of Analyst.
- LEAP Shell - M-Fab application integrated with Analyst with supported pumps. NOT A RELEASED PRODUCT (Looking for Beta Sites)
Overview
If the peaks of interest come off together in the middle of the gradient (as shown below) then it is possible to utilize the front cut and back cut time to increase throughput.
If injections are staggered in the following way, there is a potential for up to 100% gain:
Hardware Requirements
- TrioVS multiple valve system is required in addition to the standard injection valve.
