 small image & large image--Photo of SPARO showing, primarily, the "pumped pot fixture," the fixture used for switching between pumping on the pumped pot and flushing the capillary with back-pressure. Green-handled valve is used to connect pumped pot to UHP Helium gas; black-handled valve is used to connect pumped pot to mechanical pump. Photo also shows the large preamp boxes on either side, attached to which are the small laboratory JFET breakout boxes (one is aluminum, the other is painted blue).
