EMISSION SPECTROSCOPY—FLAME PHOTOMETRY AND SPECTRUM LINE PHOTOMETRY Thursday Afternoon—Terrace Room William J. Feingold, Presiding
22 ml.
This bomb has a plain cover without electrodes. It is used for sodium peroxide reactions which can be started by heat ing with a gas torch. Cups of 94% Ni, 36% Ni, 9 9 + % Ni, carbon steel and stainless steel are available. This bomb is similar to AC2E except all parts are larger and heavier than in the 22 ml. bomb. It will accommo date samples twice as large as AC2E and AC3E.
