PStQuick polystyrene calibration standards
PStQuick polystyrene calibration standards contain pre-mixed quantities of polystyrene polymers in autosampler vials for the calibration of GPC columns. Addition of solvent is all that is required for easy preparation and analysis. 12 different kits containing polystyrene polymers of various molar masses are available. Of the 12 kits, 9 are individual kits, each containing 3 to 5 polystyrene polymers. The remaining 3 are composite kits containing 2 or 3 of the individual kits.
PStQuick MP kits for calibrating TSKgel SuperMultiporeHZ columns
- PStQuick MP-N for TSKgel SuperMultiporeHZ-N
- PStQuick MP-M for TSKgel SuperMultiporeHZ-M
- PStQuick MP-H for TSKgel SuperMultiporeHZ-H
PStQuick kits to calibrate other TSKgel GPC columns and GPC columns from other manufacturers
- PStQuick Kit-L for calibrating TSKgel mixed-bed N-type columns
- PStQuick Kit-M for calibrating TSKgel mixed-bed M-type columns
- PStQuick Kit-H for calibrating TSKgel mixed-bed H-type columns
The concentrations of the polystyrene standards in the premixed vials vary from a low of 0.2mg/mL to a high of 1.6mg/mL.
All PStQuick polystyrene calibration standards are available for reordering.
Contents of each kit
For example, PStQuick Kit-M contains 20 vials each of grades C and D.

Procedure - Simply add solvent, mix and inject onto the GPC column.
Tosoh introduced its first line of
TSKgel GPC columns in 1971. Ever since, Tosoh scientists have made important contributions to advances in polymer analysis by developing state-of-the-art GPC columns for the most demanding applications.
Semi-micro columns are the TSKgel columns of choice for use with the EcoSEC GPC System. They are referred to as such since their dimensions are smaller than conventional columns in terms of internal diameter as well as in length: 4.6 mm or 6 mm ID × 15 cm vs. 7.8 mm ID × 30 cm.
