TLDR
In this paper, a hollow-cathode light source of new design has been tested in connection with a vacuum spectrograph, and the limit of detectability under the given conditions was at 0.01 μg iodine.Abstract:
On the basis of some theoretical considerations concerning the analyzability of elements that have their resonance lines in the vacuum ultraviolet, a hollow-cathode light source of new design has been tested in connection with a vacuum spectrograph. The results, which show an improvement over those reported in the literature, are tabulated. The limit of detectability under the given conditions was at 0.01 μg iodine.read more

Spectrochemical analysis by the copper spark method.
TL;DR: High sensitivity the method has the advantage that a great many elements can be determined in one exposure, so that almost any sample which can be obtained in hydrochloric acid can be analyzed for impurities without special calibration.

A hollow cathode source applicable to spectrographic analysis for the halogens and gases.
TL;DR: The relative sensitivities of fluorine spectrum lines in the vacuum ultraviolet region and in the visible region were studied, and it was found that certain visible lines are, at present, more sensitive than the theoretical raies ultimes of fluoride.

Some Characteristics of Hollow‐Cathode Discharge Tubes
TL;DR: In this paper, a study was made of the characteristic effects of the inert gas, and variations in the dimensions of the cathode, on the minimum pressure at which the Schuler discharge may be started and maintained.
