Berzelius's investigation of the action of the electric current on salts clearly demonstrated the invaluable assistance that electrolysis could render to the isolator of elements; and the adoption of this method by Sir Humphry Davy for the analysis of the hydrates of the metals of the alkalis and alkaline earths, and the results which he thus achieved, established its potency.
Further attentuation was achieved by using some lossy coax and a 24GHz connectorised circulator used as an isolator on the PA input.
I was definitely an isolator and loved drinking alone so nobody could tell the quantities I consumed.
