Scope
This document describes the principles, reagents and materials, instrumentation, sample collection and preservation, experimental procedures, and data processing of liquid chromatography-tandem mass spectrometry for the determination of cephalosporin antibiotics in wastewater, as well as accuracy and precision.
This document is applicable to the determination of 13 cephalosporin antibiotics (Cefpiramide, Cefquinome, Cefalexin, Cefazolin, Cefalexin, Cefotaxime, Cefadroxil, Cefuroxime, Cefixime, Cefazolin, Cefoperazone, Cefotetan, Cefotaxime) in domestic wastewater, aquaculture wastewater, and medical wastewater.
The detection limits of the 13 cephalosporin antibiotics in this document are 0.03 ng/L to 1.00 ng/L, and the quantification limits are 0.1 ng/L to 3.0 ng/L, as shown in Appendix A.
