GC Analysis of Active Amyl Alcohol, Isoamyl Alcohol, and C10-C14 n-Alkane Markers on SLB®-IL76i

GC Analysis of Active Amyl Alcohol, Isoamyl Alcohol, and C10-C14 n-Alkane Markers on SLB®-IL76i

Conditions

column SLB-IL76i, 30 m x 0.25 mm I.D., 0.20 µm (29869-U)
oven 90 C
carrier gas hydrogen, 40 cm/sec
sample 7 analytes in methylene chloride
injection 1 µL, 100:1 split
liner 4 mm I.D., split type, cup design
inj. temp. 250 C
detector FID, 250 C

Description

Analysis Note Active amyl alcohol and isoamyl alcohol are by-products of the fermentation process. They are of concern to alcoholic beverage manufacturers due to their aroma characteristics. In this application, both analytes and several n-alkane markers are analyzed on SLB IL76i. This inert ionic liquic column produces great peak shapes for both alcohols, resulting in great resolution.
