Improving Analytical Efficiency and Reliability of SPME Analysis through Optimal Selection of Vial Septa

User Benefits

- The detection of cyclic siloxanes from vial septa can be minimized by using the low bleed septum for SPME. - Reducing the detection of cyclic siloxanes makes data analysis easier and more efficient. - It helps prevent overlooking compounds with retention times that overlap with cyclic siloxanes, thereby supporting more reliable analysis.

Introduction

SPME (Solid Phase Micro Extraction) is a method that allows for convenient and highly sensitive analysis of volatile organic compounds. It is used in a wide range of analyses that target volatile compounds, including odor analysis and outgas analysis from chemical products. One of the challenges in SPME analysis has been the detection of cyclic siloxanes from vial septa, which often interfere with the analysis. For instance, the co-elution of sample-derived compounds and cyclic siloxanes can obscure sample-derived compounds, complicate the analysis, and potentially lead to overlooked trace compounds. To address these issues, a low bleed septum for SPME (P/N: S225-47192-91) that maximally suppresses the elution of cyclic siloxanes was developed. In this article, the fundamental performance of this low bleed septum for SPME is presented, and examples of its use in the analysis of actual products are provided.
