Bismuth might be in a decent spot for optimizing price/density/boiling point/safety if the thruster can be made of molybdenum. I'm not sure if there are more delicate components required to withstand the boiling point of

It looks like the principle is that a machine learning model trained on the combined output of four different kinds of gas sensors can discover correlations between unintentional characteristics of the sensors. For example, the manufacturer
