General Description of process:
Samples are injected and pass through a guard column which is in-line with the analytical column. At a specified time, the guard column switches out of line and is regenerated using a wash pump configured to do a step gradient while the sample peaks are acquired.
To increase throughput, samples are injected ahead of the acquisition time, so that pre-filtration is occurring concurrently with the previous samples acquisition. Each line of the sample list processes a pair of samples which are staggered in this way (see time chart at the end of this document).
4 pumps are required: - 2 wash pumps (Agilent 1200) pre-programmed to perform the step gradient and 2 isocratic analytical pumps running continuously one for each column.
