Alternate Column used for the USP® Assay Method of Tazobactam
This USP® Tazobactam Assay is easily performed and the five injection overlay below demonstrates Run to Run Precision. The Peak Efficiency is very good and USP Peak Tailing guidelines are easily met with RSD values well below 2.0%. This demonstrates a good Alternate L1 Column for your Tazobactam USP Method.

Sample Preparation: Tazobactam (0.5mg) in Mobile Phase
Note 1: Tazobactam is is a Penicillanic Acid Sulfone derivative and an Antibiotic of the Beta-lactamase inhibitor class. This compound prevents the breakdown of other Antibiotics by Beta-lactamase enzyme producing organisms.
Note 2: The Cogent Hyper-Similars C18™ HPLC Column performs very similarly to the ThermoFisher® Hypersil BD® product line.
