Laboratory Experiments
A Solenoid-Operated Gas or Liquid Saver
Michael N. Quigley
Department of Soil, Crop, and Atmospheric Sciences, Bradford Hall, Cornell University, Ithaca, NY 14853
Cover
February 1996
Vol. 73 No. 2
p. 194
Abstract
A previous note in this Journal [J. Chem. Educ. 1995, 72, 440] described the installation of a water reservoir that greatly facilitates the unattended operation of atomic absorption, emission, and plasma spectrophotometers. A further refinement is detailed here, that relates to the closure of gas valves supplying plasma spectrophotometers in particular, although chromatographs can be similarly modified.
