描述

分析報告

In this application, SPME was used for the analysis of phthalate esters from oily samples, specifically the oil-based flavor packets included with ramen noodle kits. Spiked samples of corn oil and flavored oils included with ramen noodle kits were analyzed using high temperature SPME headspace extraction using a 100 μm PDMS fiber which was then directly desorbed into the GC/MS system. Calibration standards were prepared in corn oil, and spiked samples of chicken and beef oil-based flavors were analyzed. The SLB-5ms GC columns provide consistently low-bleed, inert, efficient, and durable separations.
