Valsartan is a drug commonly used to treat high blood pressure and congestive heart failure. Legacy L1 was used to retain valsartan by reverse phase mechanism in this HPLC separation method. Legacy L1 uses embedded C18 groups on porous silica and is useful for many USP HPLC applications. Comparisons to Phenomenex columns are available by request. This simple HPLC method can be used in many pharmaceutical areas. For example, in batch production, impurity profiling, formulation and pharmacokinetics.

Legacy L1
SIELC's family of Legacy columns is based on the United States Pharmacopeia's (USP) published chromatographic methods and procedures. Numerous brands have columns used in USP reference standards and methods. USP has created various 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, allowing you to easily replace older columns that are no longer available without needing to significantly modify your method or SOPs.
