HPD™ Mix

HPD_mix

Traditional volumetric dispensers are designed for pipetting reagents or samples into vials or wells at ambient pressure or a few Bar at most. on-line volumetric reagent delivery however, may require the ability to introduce reagents into a system with a high working pressure.

Specifications

Traditional volumetric dispensers are designed for pipetting reagents or samples into vials or wells at ambient pressure or a few Bar at most. on-line volumetric reagent delivery however, may require the ability to introduce reagents into a system with a high working pressure. The HPD™ was originally designed by Spark for SPE solvent delivery in on-line SPE-LC systems, but other applications are easy to imagine. Think of pre-column reagent addition for on-line derivatization in HPLC, post-column reagent addition for detection enhancement, etc.
