Abstract
Accuracy is one of the broad areas of spectrochemical analysis where improvement by an order of magnitude would result in vast new fields of application. This paper discusses the subject under the topics of sampling, the source, electrodes, the spectrograph, photometry and calculations New techniques for reducing variables will be discussed These include optics for reducing the effects of arc wandering, the Elpac for reproducible packing of powders into electrodes, devices for mechanically traversing a flat sample during sparking, the Stallwood jet and enclosed arc chamber,
