Abstract
Accordingly, disclosed are various connectors for connecting a colorimetric sensor array to a sample bottle. These connectors allow the colorimetric sensor array to be attached to a sample bottle after autoclaving, and introduce the headspace gas to the colorimetric sensor array at the appropriate time. Examples of these connectors include (1) a needle based connector that punctures the septum of standard bottle to allow gas flow in a chamber with a colorimetric sensor array, (2) a valve based connector that attaches to a sample bottle and when the valve is opened the headspace gas has a path to diffuse to contact a sensor array, and (3) a connector that includes a breakable seal that when broken puts the headspace gas in contact with the colorimetric sensor array.
