Importance of Liner Selection in Aqueous Solution Analysis

User Benefits

- A special liner has been developed for aqueous solutions that is effective for GC analysis using water as a solvent. - By using the special liner for aqueous solutions, it is possible to obtain data with good repeatability.

Introduction

When a sample containing a lot of water is analyzed by GC, peak shapes become abnormal, and it can be difficult to analyze with good repeatability. This phenomenon is related to sample vaporization, and it is known that the analysis results differ depending on the type of liner used. Therefore, a special liner has been developed for aqueous solutions (P/N: 227-35015-01) that is optimal for analysis using water as a solvent. Examples of aqueous solution analysis include measurement of ethanol concentration in sanitizer gel in accordance with USP<611> (Application News No. G333) and analysis of ethanol in liquor (Application News No. G315). This article introduces the effectiveness of a special liner for aqueous solutions that was confirmed by two types of analyses.
