The Agilent 1200 Series RRLC system is designed for conventional LC with long columns of large internal diameter as well as for ultra-fast or rapid resolution LC with narrow bore column of about 2.1 mm id. Using a 600 bar, 2-position/6-port valve provides for switching between optimized conditions for both types of analysis.
The Agilent 1200 Series RRLC system is designed to support both conventional liquid chromatography with long columns and ultra-fast or rapid resolution applications using narrow bore columns. It achieves this versatility by allowing the adjustment of pump delay volume through a specific configuration change.
This document describes two methods for changing the delay volume: manual connection of capillaries or automated switching using a 600 bar, 2-position/6-port valve. The use of the low delay volume configuration improves peak width and height while shortening run times, particularly beneficial for low flow rates on 2.1 mm id columns.
