Rapid Analysis of the Bisphenol a in Slips of Store Receipts and ATM Machine with Head-Space Liquid-Phase Micro-Extraction Coupled to Gas Chromatography and Mass Spectrometry

Abstract:

A novel method has been developed for the determination of bisphenolA in slips of store receipts and ATM machine by head-space liquid-phase micro-extraction (HS-LPME) coupled with gas chromatography-mass spectrometry (GC-MS). The variable experimental conditions for the HS-LPME extraction process were optimized. The optimal conditions were using 2ul of toluene as organic solvent drop, 0.5g of the amount of sample and 1.0cm of the depth of micro-drop from the surface of the sample. After extracting for 10 min and detection limit of 1-100mg·L^-1. Detection limit (3 S/N) of the method was found to be 0.3mg·L^-1, precision and recovery of these methods were tested giving values of RSDs (n=6) less than 4.49%; and of recovery in th range of 98.80%-99.47%. The method shows advantages of simplicity, high sensitivity and high performance extraction to be in line with the analytical standard of the international organic pollutant.
