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.
