In this article, Roger L. Firor discusses how capillary flow technology improves the time-tested practice of backflushing in petrochemical analysis.
In this article, Roger L. Firor discusses how capillary flow technology improves the time-tested practice of backflushing in petrochemical analysis. It utilizes a purged ultimate union with virtually zero dead volume and inert connections, as well as precise midpoint pressure control, for high resolution separations. The end result is the ability to fine-tune backflush times to produce precise fraction cuts, with less maintenance and better thermal control than conventional backflush technology
