Simple Interchangeable Hollow-Cathode Lamp for Use in Atomic-Absorption Spectrometrysealed-off type, two reports by Koirtyohann .. refer to an interchangeable cathode lamp constructed from metal with a continuous inert-gas flow. Interchangeable cathode lamps are extremely useful for laboratories engaged in varying types of analysis, particularly of the “one-off” type. This note des

Versatile Gas-Metering System for Controlled Atmospheresity for some elements. In most cases, the recommended atmosphere is a mixture of two gases such as argon and oxygen. One way of obtaining such mixtures is to purchase a cylinder of gas containing a definite ratio of the two gases desired. This method, however, allows no flexibility in varying the ra

Stable Source for Plate Calibration source for emulsion calibration as ordinarily done for the photometry of emission spectra. Childs measured the absolute emission of the Hg 2537 Å line and then determined the intensities of some 55 minor lines, from 5790 to 1942 Å, relative to 2537 Å. All his tests were made with an ac supply of ab

Spurious Radiation in Littrow-Mounted Grating Monochromatorson refers to diffracted radiation that reaches the exit slit by paths other than the one for which a monochromator was designed. Such spurious radiation usually will be out of focus at the exit slit and may not be noticeable in many applications. However, its presence can lead to serious error in th

Mask for Selecting Orders for Use with the Jarrell-Ash Order Sorterher line-to-background ratios is the presence of multiple orders. If a stigmatic spectrograph (e.g., Jarrell-Ash 3.4-m Ebert) is used, the various orders can be offset or “sorted” by a device such as the Jarrell-Ash “order sorter.”. The “order sorter” is essentially a low-dispersion spectroscope whi
