Book Description

Excerpt from Spark Source Mass Spectrograph Program: July 1964 to June 1965 The radiofrequency spark source mass spectrograph has been shown in the last few years to be a useful tool for the analysis of solids for elements present down to the parts - per billion level. Because the elemental sensitivity factors vary only about one order of magnitude, semi-quantitative analysis can be obtained without the use of standards. Reports indicat that with standards i 20% accuracy is obtainable. A most im portant feature of this method of analysis is the absence of inherent blind spots; in many matrices all elements are detect able at the parts-per-billion level. The blind spots that do appear come from the matrix itself and in high purity samples are generally limited to a few elements.
