Analytical parameters of analysis of Histamine.

Compound	Mr (g·mol−1)	Regression Equation	Linear Dynamic Range (μg·mL−1)	R2	LOD (μg·mL−1)	LOQ (μg·mL−1)	RSD (%)
Histamine	111.2	y = 0.3234x	3.0–100.0	0.996	2	7	2.0

Mr stays for molecular mass; R² for coefficient of determination; LOD for limit of detection (3 S/N); S/N means signal/noise ratio where S is the peak area of the lowest detectable signal of analyte and N is expressed as standard deviation (SD) of noise determined in the signal domain; LOQ for limit of quantification (10 S/N) and RSD for relative standard deviation calculated from three measurements of Histamine standard peak areas (100 μg·mL⁻¹; injection 100 μL per sample).
