Methane content (biogas composition) measurements from nine batch reactors.
data("comp")A data frame with 132 observations on the following 4 variables.
ididentification code, a unique value for each reactor in the dataset. A factor with levels 2_1, 2_2, 2_3, 2_4, 2_5, 2_6, 2_7, 2_8, 2_9, 2_10, 2_11, and 2_12
date.timedate and time of mass measurement, a POSIXct object.
dayselapsed time of mass measurements (from reactor setup) in days, a numeric vector.
xCH4biogas methane content as a mole fraction, excluding water and all other gases other than carbon dioxide, a numeric vector
These data are meant to be example data for multiple functions, e.g., interp, cumBg, or summBg.
Reactors were 500 mL glass serum bottles with butyl rubber septa and screw caps.
Methane and carbon dioxide contents were determined by gas chromatography using a thermal conductivity detector and normalised so methane and carbon dioxide sum to 1.0.
Data in vol, mass, comp, and setup are from the same reactors.
