SPECIAL | |
Application ID | |
M-003 | |
Description | |
High Throughput LC injections alternating onto two analytical columns. |
Overview
This configuration allows shorter cycle times by limiting the acquisition time to just the peaks of interest and regenerating the alternating column during the acquisition. It uses
Cycle Composer Software[1] - this application is run with Standard LEAP macros outside of Analyst Software[2] from Applied Biosystems Inc
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.
