Linear Calibration Type
Organic SEC (GPC) columns
LF
> Employs a special packing material with a wide pore size distribution (multi pore type)
> Highly linear calibration curve without inflection points
> Molecular weight distribution can be determined with high precision
> Enables analysis over a broad range of molecular weights
> Column for rapid analysis (LF-604) and column for high performance analysis (LF-404) enabling reduction in solvent use are also available
> Corresponds to USP L21
Please refer to Replacement of In-Column Solvent
*Use of the LF-604 and the LF-404 with semi-micro type devices is recommended.
