Quantitative Analysis of Biomass Samples
A method for quantifying a cellulosic component in a sample includes hydrolyzing the sample in a single acid hydrolysis step of the sample in aqueous sulfuric acid having a concentration of 15 wt-% to 60 wt-%, at an incubation temperature of 50° C. to 98° C., at ambient pressure, for an incubation period of 30 min to 360 min; separating a supernatant from the hydrolyzed sample in aqueous sulfuric acid; analyzing the supernatant for total content of glucose and xylose and one or more of mannose, galactose, and arabinose; and calculating, based on the analysis, the amount of the cellulosic component, wherein the cellulosic component includes hemicellulose, cellulose, or both.
Quantitative Analysis of Biomass Samples
A method for quantifying a cellulosic component in a sample includes preparing a first suspension by mixing an amount of sample with first aqueous acid at a concentration of 40 wt-% or greater; incubating the first suspension in a first incubation stage at a first incubation temperature of less than 40 °C; adding water or aqueous sulfuric acid to the incubated first suspension to form a second suspension having a concentration 40 wt-% or less of sulfuric acid based on a total weight of the second suspension; incubating the second suspension in a second incubation stage at a second incubation temperature of 50 °C or greater for an incubation period, wherein the sample is not subjected to hydrolysis at temperatures above 98 °C; separating a supernatant from the incubated second suspension; analyzing the supernatant for total content of xylose, mannose, galactose, and arabinose; and calculating, based on the analysis, the amount of the hemicellulose.
