Materials 2,2,4-Trimethylpentane (isooctane), formic acid, p -anisidine, 4-methyl-1-pentanol, aluminum oxide (Brockman Grade 1), BHT, sand, volatiles standards, ammonium thiocyanate, ferrous chloride, and food grade mixed tocopherols (Toco) were purchased from Sigma-Aldrich (St. Louis, MO, USA). According to the manufacturer's report, Toco contained 74.0% total tocopherols including 13.2% α-, 0.16% β-, 42.9% γ-, and 16.3% δtocopherols in weight. A commercial rosemary extract (RE) was generously provided by DuPont (Wilmington, DE, USA), which contained the mono-diglycerides of fatty acids, acetic acid esters of mono-and diglycerides of fatty acids, propylene glycol, 3.8-4.7% carnosic acid and carnosol, and 4.0-4.7% phenolic diterpenes according to the product description. Soybean oil (SBO) was purchased from a local grocery store. Fish oil (FO) was purchased from Nordic Naturals (Watsonville, CA, USA). Hexane, methanol, acetic acid, isopropanol, acetonitrile, dichloromethane, and ethyl acetate were purchased from Fisher Scientific (Fair Lawn, NJ, USA).
Volatiles standards
Manufactured by Merck Group
Sourced in United States
Volatiles standards are a type of lab equipment used to calibrate and validate analytical instruments that measure volatile organic compounds (VOCs). They provide a known concentration of target VOCs to ensure accurate and reliable measurements. The core function of volatiles standards is to serve as a reference for the quantitative analysis of VOCs in various samples.

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.
