HPLC Determination of Cefepime on Primesep 100 Column
August 5, 2021
Separation type: Liquid Chromatography Mixed-mode
High Performance Liquid Chromatography (HPLC) Method for Analysis Cefepime
Cefepime is a fourth generation cephalosporin antibiotic usually reserved for treatment of severe nosocomial pneumonia and febrile neutropenia as well as multiple drug-resistant microorganisms such as Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococcus pneumoniae. Cefepime can be retained on the Primesep 100 mixed-mode column using an isocratic analytical method with a simple mobile phase of water, acetonitrile (MeCN, ACN), and sulphuric acid (H2SO4) buffer. The analysis method can be UV detected at 270 nm.
| Column | Primesep 100, 4.6×150 mm, 5 µm, 100A |
| Mobile Phase | MeCN/H2O – 30/70% |
| Buffer | H2SO4 – 0.5% |
| Flow Rate | 1.0 ml/min |
| Detection | UV 270 nm |
| Class of Compounds |
Drug |
| Analyzing Compounds | Cefepime |
Application Column
Primesep 100
The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers.

HPLC Analysis of Cefepime
August 6, 2015
Cefepime is a fourth generation cephalosporin antibiotic usually reserved to treat severe nosocomial pneumonia and febrile neutropenia as well as multiple drug-resistant microorganisms such as Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococcus pneumoniae. Legacy L1 was used to retain Cefepime by reverse phase mechanism.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.

| Buffer | NaH2PO4 pH 5.0- 5 mM |
| Flow Rate | 1.0 ml/min |
| Detection | UV, 250 nm |
| Class of Compounds |
Drug, Hydrophilic, Ionizable |
| Analyzing Compounds | Cefepime |
Application Column
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.
