This document introduces the features of the imported brand Capillary Flow Technology, including ease of use, ruggedness, inertness, usability to> 350 oC, excellent exclusion of air, no unpurged volumes, no porous materials into which compounds can dissolve ( peak tailing), fast thermal response, no outgassing or shedding of particles.
This document is a technical presentation titled "Advances in Capillary Column Backflushing" delivered at ISCCE 2010 by Matthew S. Klee of Agilent Technologies. It outlines the benefits of capillary flow technology, such as ruggedness and inertness up to 350°C, and details the process for setting up backflush configurations.
Symptoms include long stabilization time and cycling pressure (P), which occur because proportioning valve duty cycle should never be 0%.
Adding a bleed ensures stable pressure control. This can be achieved using either a fixed bleed or a variable bleed.
