A modified king furnace for absorption spectroscopy of small samples.
A miniaturized King-type furnace has been constructed, which consists of an inductively heated, small diameter tantalum tube supported in a radiation shield of unconventional design. Because of the clean construction, useful metal vapor absorption spectra can be obtained using samples weighing only a few milligrams. Details of the construction and operation of the furnace are discussed, and typical spectra showing extended series in barium, calcium, thallium, and radium are presented.
