calculate_concentrations: Calculate the concentrations of the source samples

In sebkopf/isorunN2O: Process IRMS runs of N2O analyses.

Description

Calculate the concentrations of the source samples

Usage

calculate_concentrations(
  data,
  area,
  volume,
  dilution = 1,
  conc_pattern = "(\\d+)uM",
  standards = category %in% c("USGS-34", "IAEA-NO3"),
  quiet = FALSE
)

Arguments

data	(can be a grouped_by data set)
area	the area column
volume	the volume column
dilution	the dilution column (if any)
conc_pattern	the regular expression pattern to capture the concentration from the standards 'name' colum
standards	selection criterion for the standards to consider

Value

introduces the columns 'conc', 'amount' and the parameters 'p.yield' and 'p.run_size'
