Attached files are pulse height profiles of recent DME ageing tests:

E2PRF.PS - AWM2100V mass flowmeter in flow path

E3E4PRF.PS - E3 - "Pure" DME (i.e. no additional materials in flow path)

                        E4 - R311 activated copper O2 filter in flow
path

E5E6PRF.PS - E5 - 2 ton epoxy, conductive epoxy, plastic connector, 1
part RTV all  in                   2 copper containers in series in flow
path
                        E6 - initially just an empty copper container in
flow path,
                                later (after 0.081 C/cm-wire) put 2 part
RTV in container

E7E8PRF.PS - E7 -2 ton epoxy in copper container in flow path
                        E8 - plastic cable connector in copper container
in flow path

E9E10PRF.PS - E9 - conductive epoxy in copper container in flow path
                            E10 - 1 part RTV in copper container in flow
path

E11E12PR.PS - E11 - "Silguard" RTV in copper container in flow path
                            E12 - Urethane rubber in copper container in
flow path

NOTE:  in addition to above chamber specific materials ALL chambers were
fed from a common gas system containing various regulators, valves,
rotameters, tubing, etc.   Thus all the DME gas was exposed to stainless
steel, copper, zinc, brass, aluminum, chrome, polyethylene, natural
rubber, viton, buna-N, neoprene, teflon,  and glass prior to entering
the test chambers.
