Convert gas concentration to quantity using the Ideal Gas Law

Description

Convert gas concentration to quantity using the Ideal Gas Law

Usage

ffi_ppm_to_umol(ppm, volume, temp, atm)

ffi_ppb_to_nmol(ppb, volume, temp, atm)

Arguments

ppm

Gas concentration (ppmv), numeric

volume

System volume (chamber + tubing + analyzer, m3), numeric

temp

Optional chamber temperature (degrees C), numeric

atm

Optional atmospheric pressure (Pa), numeric

ppb

Gas concentration (ppbv), numeric

Value

The quantity value, in micromoles (for ffi_ppm_to_umol) or nanomoles (for ffi_ppb_to_nmol).

Note

If temp and/or atm are not provided, the defaults are NIST normal temperature and pressure.
