In-House Reference Material of Chloramphenicol in Pig Muscle

Open access

Abstract

An in-house reference material of chloramphenicol (CAP) in pigs muscle was prepared from the chloramphenicol treated animals. The incurred muscle material was diluted by mixing with blank muscle sample. The concentration of CAP at the level 0.33 μg kg−1 was reached. For the homogeneity study, 10 random samples were analysed and the results were interpreted by Cochran’s test and the sufficient homogeneity test. Additionally, the samples were tested for their stability according to the following scheme: 1, 7, 14, 28, 56, 84, and 112 d. It was confirmed that an appropriate homogeneity and stability of the produced in-house reference material was obtained.
