Abstract
Analysis of nitrosodiethylamine (NDEA) in Indonesia salted fish with hollow fiber-liquid phase microextraction gas chromatography flame ionization detector
Author(s): Yanuardi Raharjo, Usreg Sri Handajani and Miratul KhasanahHollow fiber liquid phase microextraction (HF-LPME) is one of sample preparation techniques that is used for separating analyte from sample and enriching the analyte. In this research, HF-LPME-GC-FID is applied for analyzing NDEA compound in salted fish from traditional market and supermarket. This method is supported with gas chromatography completed by flame ionization detector as a detector. The optimization of analytic parameters is ethyl acetate as organic solvent, the optimum stirring rate is 252 rpm, and the optimum temperature is 30°C. The linier calibration curve of NDEA analysis with HF-LPME-GC-FID technique have coefficient correlation (R2) 0.9998, limit of detection 0.645 ppb, accuracy between 99.61-100.16%, precision between 0.24-1.33%, and enrichment factor 999.8 times.
