Thermo Fisher Scientific Inc. has developed a rapid ion
chromatogaphy (IC) method to determine the common sugars in samples from
solutions used for biofuel
production. 
The method described in Application Note 282:
Rapid
and Sensitive Determination of Biofuel Sugars by Ion Chromatography
requires minimal sample pretreatment and uses a Dionex CarboPac SA10 anion-exchange
column with electrolytically
generated hydroxide eluent and high-performance anion-exchange
chromatography with pulsed amperometric detection (HPAE-PAD).
Corn
stover, a common feedstock for biofuel alcohol production, consists of the
leaves and stalks of maize plants left after harvesting. It is critical to
determine carbohydrates during biofuel alcohol production to ensure process
yield and product quality. The carbohydrates in biomass samples are often
quantified by high-performance liquid chromatography (HPLC) using refractive
index detection. The refractive-index-based method is not specific, and could
have interferences from other compounds in the complex biomass matrices.
