The dummy gauge is wired into a Wheatstone bridge on an adjacent arm to the active gauge so that the temperature effects on the active and dummy gauges cancel each other . ( Murphy's Law was originally coined in response to a set of gauges being incorrectly wired into a Wheatstone bridge .)

In 1920-1921 he undertook graduate studies in mathematical physics at Harvard University, then spent a year at the Radio Frequency Laboratories in Boonton, New Jersey, where he worked on radio receivers and made inventions for stabilization of radio-frequency amplifiers via a Wheatstone bridge, linear detection at high signal levels, and automatic volume control.

In a typical experiment, a packed column is used to separate the light gases, which are then detected with a FID . A complication with light gas analyses that include H 2 is that He, which is the most common and most sensitive inert carrier ( sensitivity is proportional to molecular mass ) has an almost identical thermal conductivity to hydrogen ( it is the difference in thermal conductivity between two separate filaments in a Wheatstone Bridge type arrangement that shows when a component has been eluted ).
