This note describes the operation of two Agilent 1100 autosamplers in a 1100 system. In order to achieve a high sample throughput both autosamplers are used. While one of the autosamplers is injecting, the other one is in the by-pass position and vice versa.
The document explains how to operate two Agilent 1100 autosamplers simultaneously within one HPLC system. By using specific macros (MALS1.MAC and MALS2.MAC), the system ensures that while one autosampler is injecting, the other remains in a bypass position to minimize dead volume.
It is necessary to replace the resident and operational firmware by firmware with a revision greater than 4.02.32.
The order is determined by verifying the ALS number before running an analysis, as the order may change during boot-up.
