What is inside a GPC column?

 Points on GPC column:

• A typical Gel Permeation Chromatography (GPC) column contains calibrated porous beads that function as molecular sieves for polymer separation.
• These beads are manufactured from cross-linked polymers or silica and engineered with precisely controlled pore diameters.
• This carefully designed pore architecture ensures predictable polymer fractionation and highly reproducible chromatographic performance.
