A simple method to assess the impact of sealing, headspace mixing and pressure vent on airtightness of manual closed chambers

The data set contains data from a full-factorial laboratory experiment, were three different designs and two modifications of typical manual closed chamber setups were tested for sealing integrity. Tests were performed using a simple method, based on injections of single CO2 pulses. Chamber designs differed in V:A-ratio nand chamber-collar sealing (water, rubber-foam, rubber-tube). All chambers were tested with and without pressure vent and fan. Included are measured CO2-concentration data as well as calculated sealing integrity in terms of chamber leakage. Results indicate significant differences in sealing integrity due to chamber-collar sealing strategy. The effect of pressure vent and fan, however, is of minor importance.
