An open-source, automated, gas sampling peripheral for laboratory incubation experiments using cavity ring-down spectroscopy.

ABSTRACT: Spectroscopic instruments are becoming increasingly popular for measuring the isotopic composition and fluxes of a wide variety of gases in both field and laboratory experiments. The popularity of these instruments has created a need for automated multiplexers compatible with the equipment. While there are several such peripherals commercially available, they are currently limited to only a small number of samples (≤16), which is insufficient for some studies. To support researchers in constructing custom, larger-scale systems, we present our design for a scalable gas sampling peripheral that can be programmed to autonomously sample up to 56 vessels - the "multiplexer". While originally designed to be used with a Picarro cavity ring-down spectroscopy (CRDS) system, the multiplexer design a
