Supplier: VARIAN

The quickest and most convenient method to deliver an accurate 12 point column calibration for organic and aqueous GPC/SEC column calibration.

Supplier: VARIAN

Polystyrene standards for many organic solvents either for conventional GPC column calibration or for calibrating light scattering and viscosity detectors that provide equidistant calibration points for greater accuracy.

Supplier: VARIAN

Polymethylmethacrylate (PMMA) standards are extremely versatile as they can be used for organic GPC with a wide range of medium polarity eluents, such as tetrahydrofuran, toluene, methyl ethyl ketone and ethyl acetate.

Supplier: VARIAN

The EasiCal system for organic solvents consists of two different combs, each with ten detachable spatulas supporting a mixture of five polymer standards with MWs selected to provide equidistant calibration points for greater accuracy.

Supplier: VARIAN

These hydrophilic polymers are suitable for both aqueous SEC and organic GPC using the majority of polar organic solvents. The two types are chemically similar that can be used together across a wider molecular weight range with aqueous and organic polymers.

Supplier: TOSOH Bioscience

These standards consists of bulk quantities of polystyrene and polyethylene oxide standards of varying molar mass and pre-mixed quantities of polystyrene polymers for calibration of GPC columns.

Supplier: LGC Standards PROMOCHEM
