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

 

PSS has developed Lux columns especially for GPC/SEC-light scattering to improve data quality for light scattering detectors.

 

Lux columns are available with different column materialsparticle sizes, and porosities, as linear and as single porosity columns.  

 

Ultra pure packing materials that yield excellent signal to noise ratio during on-line light scattering measurements.  Available  in single porosity  or linear (mix bed) columns:

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