Summary

Pretreatment methods for conversion of plant biomass to fuels and valuable chemicals begin with a chemically complex feedstock which is fractionated into liquid and solid phases, presenting a significant challenge from the perspective of analytical chemistry. Traditional wet chemical analytical methods are widely used in academic and industrial settings and are currently being vetted as international standards. The main limitation of these methods is their per-sample cost and their complexity, which delays results for days or even weeks. This chapter focuses on the development, validation, and application of high-throughput (HTP) methods for monitoring pretreatment processes. The HTP methods described here are rapid analysis methods based on a combination of near-infrared (NIR) spectroscopy and advanced multivariate analysis techniques. HTP rapid analysis methods are capable of characterizing complex substrates with excellent mass closure delivering the precision and accuracy needed to understand pretreatment processes. Following the guidelines given here, robust, accurate and precise analytical methods can be developed to support the optimization and monitoring of pretreatment processes. Once calibrated and validated, the simplicity and low per-sample cost of these methods provide a realistic path to levels of information that would have been too expensive to pursue using traditional methods. When calibrated using appropriate samples and high-quality data, rapid analysis methods can perform well in many environments, with most operators and for decades with minimal updates
