Sodium hydroxide, perchloric acid, phosphoric acid, acetic acid, citric acid, sodium citrate, sodium acetate, ascorbic acid, sulfuric acid and potassium metabisulphite were analytical grade chemicals and were purchased from Tianjin Chemical Factory. HPLC grade solvents, including ethanol, methanol and dichloromethane, were purchased from Honeywell (Marris, Township, NJ, USA). Polyvinylpolypyrrolidone and d -gluconic acid lactone were purchased from Sigma-Aldrich (St. Louis, MO, USA). Pure standards of volatile compounds were purchased from Sigma-Aldrich (St. Louis, MO, USA).
Pure standards of volatile compounds
Manufactured by Merck Group
Sourced in United States, Italy
Pure standards of volatile compounds provide reference materials for the identification and quantification of volatile organic compounds in analytical testing. These standards offer high purity and accuracy to support reliable and precise measurements.

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.
