SIELC Legacy L1 HPLC column

Legacy L1

SIELC’s family of Legacy columns is based on United States Pharmacopeia’s (USP) published chromatographic methods and procedures. A plethora of brands have columns used in USP reference standards and methods, and USP has created different designations to group together columns with similar types of packing and properties in the solid phase. SIELC's Legacy columns adhere to these strict requirements and properties so that you can easily replace older columns that are no longer available without having to significantly modify your method or SOPs.
