I wonder if there is a simple test .. like the binary test to see if xtol has died or regular print developer is dead ( putting a scrap of film or paper in it with the lights on to
see if it reacts and how fast ) with glycin ( or metal or HQ &c to know how well the raw components are working... simpler the better because the more complex the test the easier it is
to screw it up ( or at least that is true for me ) ...
