Ion Chromatographic Determination of
Histamine in Fish with Series Bulk Acoustic Wave Detection
X. Yang, B. Yu, L. Nie, and S.

The determination of histamine in fish using an unsuppressed ion chromatographic (IC) method with series bulk acoustic wave (SBAW) detection is developed. The advantages of the good selectivity of IC and the highly sensitive response of SBAW are combined to improve detection limit, accuracy, and reproducibility. The detection limit is 8 ng, recoveries are 98–106%, and the relative standard deviation is 1.6%. For the IC analysis, the analytical column is a Shim-pack IC C1 column, and the mobile phase is a 2.5mM HNO3 solution. The fish samples are treated with trichloroacetic acid and purified with either n-pentanol or n-hexanol. Histamine is finally isolated with a 0.2M HCl solution. The method is applied for the determination of histamine levels in black carp.
