PSS manufactures and produces different GPC/SEC column types for a variety of applications:

Lux Column preview
Columns for Light Scattering Detection

Lux columns reach the steady state mode > 25 times faster than conventional columns, and their overall noise reduction is more than 25 times better.

Traditional GPC/SEC columns can produce excessive baseline noise from particulates in the eluent stream, which can significantly deteriorate the quality of the light scattering detectors data (especially LALLS/LALS)  Normally a new column set needs a 'conditioning' process, which involves flushing the columns to waste without any detector connected.

HighSpeed vs. Analytical Columns 

A HighSpeed column (red line) reduces the run time for a sample (broad Poly(styrene)) by a factor of 6 - 8 compared to a conventional column (black line).

HS will substitute for analytical columns without modifications to your LC system, as long as pump and detectors accommodate 6.25 ml/min. At this flow rate, you will speed up the measurement using the same amount of solvent you currently use.

Calibration with Poly(styrene) ReadyCal green, red, and white: each contains 4 different molecular weight standards.

PSS offers a wide variety of column dimensions and will manufacture custom sizes upon request. 

PSS uses stainless steel (V4A) columns of standard dimensions that fit any HPLC or GPC/SEC instrument.
