Exploring the stability and repeatability of a hollow core fiber Raman gas sensor
In this paper we present an exploration of the stability and repeatability of a hollow core microstructured fibre (HCMOF) Raman gas sensor. Raman gas detection using HC-MOFs is an exciting technique as it enables high sensitivity, multi-species detection using a small gas volume and within a small physical space. Several previous works have demonstrated the utility of HC-MOF fibres as Raman gas cells for the detection of a wide range of gas species such as methane and hydrogen. Here we take a first look at the Raman signal stability (in a single fibre) and signal reproducibility (from fibre-to-fibre). We show that a HC-MOF Raman system can achieve low within-day variability of 0.3 %CV and fibre-to-fibre variability of 7.6 %CV. Understanding the error within systems such as the one presented is critical in the development of HC-MOF-based gas sensors for practical applications.

Abstract
In this paper we present an exploration of the stability and repeatability of a hollow core microstructured fibre (HCMOF) Raman gas sensor. Raman gas detection using HC-MOFs is an exciting technique as it enables high sensitivity, multi-species detection using a small gas volume and within a small physical space. Several previous works have demonstrated the utility of HC-MOF fibres as Raman gas cells for the detection of a wide range of gas species such as methane and hydrogen. Here we take a first look at the Raman signal stability (in a single fibre) and signal reproducibility (from fibre-to-fibre). We show that a HC-MOF Raman system can achieve low within-day variability of 0.3 %CV and fibre-to-fibre variability of 7.6 %CV. Understanding the error within systems such as the one presented is critical in the development of HC-MOF-based gas sensors for practical applications.
