Using the Samples method to measure small volume subsamples from larger volume samples by taking a 1–2 mL subsample gas from larger sample and injecting into smaller cuvettes (a). As an example, different concentration of ethylene in 1800 mL glass jars was measured by injecting 2 mL of sample gas into 10 mL cuvettes (b). The black filled pentagram is the measurement of the reference cuvette
