Effect of Solvent-peak Separation Column on Separation (1)

A solvent-peak separation column, GPC KF-800D is used with KF-806M to improve the separation at low molecular weight range.

Sample :
1. PS, Polystyrene (MW : 401,000)
2. PS, Polystyrene (MW : 156,000)
3. PS, Polystyrene (MW : 28,500)
4. PS, Polystyrene (MW : 2,450)
5. Ethylbenzene (MW : 106)

 Columns : (1); Shodex GPC KF-806M (8.0mmID*300mm) x 2
 (2); Shodex GPC KF-806M (8.0mmID*300mm) x 2 + KF-800D (8.0mmID* 100mm)
 Eluent : THF
 Flow rate : 1.0mL/min
 Detector : UV(254nm)
 Column temp. : 30°C
