GPC/SEC instrument

 

Name / equipment: GPC/SEC  

Manufacturer / Brand: Agilent Technologies  

Model: Agilent 1260 Infinity Quaternary LC

Scope of usage: Gel permeation chromatography is a type of liquid chromatography where substances are separated by their size. It is relative but important method for molecular weight and molecular weight distribution determination. Agilent LC enables chromatography with four different isocratic or gradient changing solvents at a time. With different columns or their combinations molecular weight and it’s distribution of all soluble polymers can be determined.    

Examples of application for polymer analysis / information that can be obtained by this method for polymers: Average molecular weight, molecular weight distribution and hydrodynamic volume of soluble polymers can be determined.  

Measurement range: Mw from 380 to 10.000.000 Daltons  

Sample limitations: Samples have to be completely soluble in mobile phase tetrahydrofuran (THF) or dimethylacetamide (DMAc) up to maximum 45°C of eluent and column temperature. Analyzed samples should not interact with the stationary phase in the column.  

Limitation of application conditions: working temperature is between ambient temperature to 45°C.
