Variable analysis
- Eluent (carbon disulfide)
- Extraction method (ultrasonic waves for at least 30 min)
- Qualitative information about the predominant VOCs
- Quantitative information about the concentrations of target analytes (benzene, ethylbenzene, xylene, toluene, styrene, n-hexane, n-heptane, n-nonane, trichloroethylene, tetrachloroethylene, n-butyl acetate, n-octane, n-decane, dichlorofluoromethane, and acetone)
- Carrier gas (helium) and flow rate (2 mL min^-1)
- Injection volume (1 μL) and split ratio (5/1)
- Column dimensions (length = 30 m, internal diameter = 0.25 mm)
- Column temperature program (initial 50 °C, increased to 100 °C after 5 min)
- Injector temperature (250 °C)
- Analytical instrument (gas chromatography-mass spectrometry and gas chromatography with flame ionization detector)
- Standard solutions of benzene, ethylbenzene, xylene, toluene, styrene, n-hexane, n-heptane, n-nonane, trichloroethylene, tetrachloroethylene, n-butyl acetate, n-octane, n-decane, dichlorofluoromethane, and acetone

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.
