Example of Use of Alternate Carrier Gas in GC Analysis: Change from He Gas to N2 Gas

Introduction

Helium (He) has mainly been used as the carrier gas for gas chromatography (GC), but limited availability and a sharp rise in the price of He have become issues. In recent years, hydrogen (H2) and nitrogen (N2) have been actively used as alternate carrier gases for He. As an example of an analysis in which the carrier gas was changed from He to N2, this article introduces an example of an analysis by the vegetable oil (olive oil) immersion method for plastic materials using GCFID. In this analysis, we used the overall migration test referred to the European Committee for Standardization, EN1186 “Materials and articles in contact with foodstuffs - Plastics (No 10/2011)”
