Abstract

The aim of this paper is to study the interactions between plastic packaging which is used to store salted serum at 0.9% of NaCl and the physiological liquid. For this purpose, the bags were stored in real conditions of storage by respecting temperatures and time of conservation. Samples were taken off every 4 months to be analyzed.Fourier transform infrared (FTIR) spectroscopy was used to investigate the migration phenomena, the atomic absorption spectrometry (AAS) was used to follow the migration's evolution of metals from bag's plastic and the gas chromatography coupled with mass spectrometry (GC/MS) was used for the determination of DOP migration.The results obtained by the three techniques showed the migration of the serum bags additives in the physiological liquid. This migration depends on time contact.
