Packed Column Analysis of Alcohol Number Determination Conforming to Japanese Pharmacopoeia Using Nexis™ GC-2030 (FID)

Introduction

The methods of alcohol number determination provided in the Japanese Pharmacopoeia (JP) are Method 1 Distilling method and Method 2 Gas chromatography as for the tincture or other preparations containing ethanol. In these methods, the alcohol number is determined by reading the number of milliliters (mL) of ethanol distillate obtained from 10 mL of a sample measured at 15 °C. In the gas chromatography method, a packed column is used. This article introduces an example of alcohol number determination as provided in the JP using a Nexis GC-2030 gas chromatograph, which now also supports packed column analysis.
