Description

Application

• A chemiluminescence method for screening of fluoroquinolones in milk samples based on a multi-pumping flow system.: This study presents a method for detecting fluoroquinolones in milk, using a multi-pumping flow system integrated with chemiluminescence detection facilitated by ammonium cerium(IV) nitrate. The research highlights the application of ammonium cerium(IV) nitrate in enhancing chemiluminescence and improving detection limits in food safety assays (Vakh et al., 2019).
