Product instruction

Eluents:

The shipping solvent is Tetrahydrofuran (THF). The in-column solvent can be replaced. Following eluents are suitable:

THF
Chloroform
Carbon tetrachloride
Toluene
Methyl ethyl ketone
Acetone
Dimethylformamide (DMF) Usable at 40°C or higher)
Dimethylacetamide (DMAc) (Usable at 40°C or higher)
Hexafluoroisopropanol (HFIP) (Usable at 40°C or higher)
N-Methylpyrrolidone (NMP) (Usable at 40°C or higher)
Dimethylsulfoxide (DMSO) (Usable at 40°C or higher)

Guard column:

The use of the guard column GPC LF-G is recommended.

Cleaning and Regeneration:

Clean the guard column and analytical column separately by running the eluent at 50% of standard flow rate in the opposite direction of the arrow on the column tag in order to remove the clogged substance.
