HighSpeed Columns for Macromolecular Liquid Chromatography

20x50mm Stainless Steel HighSpeed ColumnShop High Speed Columns

The PSS HighSpeed family of columns permits dramatic reductions in GPC analysis time for polymers > 2000D, without loss in resolution, accuracy or reproducibility. PSS HighSpeed columns (20mmx50mm) have a larger diameter and a shorter length than their typical analytical counterparts (8mm x 300mm), and the ability to operate at optimum flow rates of 6.25 ml/min while keeping same linear flow, equal resolution and polymer information: Mw, Mn, Mp and PDI. They have unparalleled ability to produce a 12 point calibration curve in just ten minutes; (Polystyrene 374 to 2.3Million D shown below).  Optimum column design helps expedite product screening, process control, and rapid sample throughput.
These columns can substitute the analytical columns without modifications to your LC system, as long as your pump and detectors can accommodate 6.25 ml/min.  At this flow rate, you will use the same amount of solvent you currently use, but your elution occurs quicker.   Our claim is not that you will save eluent, but that you will save   precious time.
HighSpeed columns are available with different column materials, particle sizes, and porosities, as linear and as single porosity columns.
