A fantastic session with the glove box today......for the experiment I had made a number of very specific structural objects in terms of their mechanics but more importantly in terms of the materials used. This is so that they can be operated within the narrow restrictive parameters of the glove box - one of the very specific spaces in which science is undertaken. The gas in a glovebox is pumped through a series of treatment devices which remove solvents, water and oxygen from the gas. Oxygen is removed by passing a hydrogen/nitrogen mixture through copper metal while it is heated: the water formed is passed out of the box with the excess hydrogen and nitrogen so I had to make devices that take this issue on board. A sideways thought - the idea of evidence of activity - documenting the other - it might be interesting in some way to look at the trace materials extracted that is sucked off and out of the materials and held in the suspension.
