Area of Science:

• Biomass Valorization
• Analytical Chemistry
• Renewable Energy

Background:

• Lignocellulosic biomass is a key renewable resource for sugars and energy.
• Biomass processing generates organic acids and furans, requiring robust analytical methods.
• Existing methods for analyzing these compounds have limitations.

Purpose of the Study:

• To develop and optimize an ultra-high-performance liquid chromatography (UHPLC) method for identifying and quantifying organic acids and furans.
• To evaluate the method's accuracy and efficiency for analyzing biomass hydrolysates.

Main Methods:

• UHPLC coupled with a diode array detector and ion chromatography columns was employed.
• Chromatographic conditions, including column temperature and mobile phase flow rate, were systematically varied.
• Calibration curves, resolution, limits of detection and quantification, and recovery rates were determined.

Main Results:

• Optimized conditions were established for analyzing succinic acid, lactic acid, formic acid, acetic acid, 5-hydroxymethylfurfural, and furfural.
• Specific flow rates and temperatures were identified as optimal for different compound groups.
• High accuracy was demonstrated through compound recovery in wheat straw hydrolysate.

Conclusions:

• The developed UHPLC method provides accurate and reliable quantification of key organic acids and furans from lignocellulosic biomass.
• This method supports the efficient analysis of biomass-derived compounds for energy and biochemical applications.
• Optimized chromatographic conditions enhance the analytical performance for diverse biomass-derived molecules.
