Organic SEC (GPC) Columns: Linear Calibration Type

LF · Employs a special packing materials with a wide pore size distribution (multi pore type)
· Enables analysis over a broad range of molecular weights (100 to2 million)
· Highly linear calibration curve without infection points
· Molecular weight distribution can be determined with high precision
· Column for rapid analysis (LF-604) and columns for high performance analysis (LF-404) enabling reduction in solvent use are also available

Please refer to Replacement of In-Column Solvent
*Use of the LF-604 and the LF-404 with semi-micro type devices is recommended.
