The release of 1-butanol (1-BuOH) was used to determine the rate of hydrolysis from TBOS. Samples were prepared for injection using a Tekmar Lumin heated purge and trap concentrator with an Aqua Tek 70 Liquid Autosampler (Teledyne Tekmar, Mason, Ohio, United States). Samples were injected into a HP 6890 Series Gas Chromatograph with a 5973 Agilent Mass Selective Detector (GC-MS). The GC-MS was fitted with a Restek Rtx-VMS capillary column (Restek, Bellefonte, Pennsylvania, United States) to separate compounds. The GC-MS received injections of diluted aqueous samples from batch bottles while in the single-ion monitoring mode for m/z of 56 to measure 1-BuOH in the samples.

LGO, HMF, and furfural were analyzed using a GC (Shimadzu, GC-2010 Plus equipped with a flame ionization detector and a Restek RTX-VMS capillary column). The injection port and the detector were held at 240 °C. The column flow rate was 1 mL/min with a He carrier gas. The GC oven temperature was initially held at 40 °C for 5 min, ramped to 240 °C at 7.5 °C/min, and kept at 240 °C for 15 min. For each analysis, the injection volume was 1 μL.
LG, glucose, xylose, and arabinose were analyzed using HPLC (Shimadzu, LC-20) equipped with UV (UV–Vis; SPD-20AV) and RI (RID-10A) detectors. Separation was achieved using a Bio-Rad Aminex HPX-87H column at 35 °C with 5 mM H2SO4 as mobile phase, flowing at a rate of 0.6 mL/min. For each analysis, the injection volume was 10 μL.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
