GPC/SEC Lux Columns - pre-equilibrated for on-line Light Scattering
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 materials and procedurs for columns to be used for GPC/SEC-light scattering to improve data quality for light scattering detectors.
Lux columns are available with different column materials, particle sizes, and porosities, as linear and as single porosity columns.
Order numbers:
P/N 299-2201: Pre-equlibration for LS measurements of Analytical column
P/N 299-2200: Pre-equlibration for LS measurements of Precolumn
Lux columns reach the steady state mode > 25 times faster than conventional columns, and their overall noise reduction is more than 25 times better.
