The limiting factor to the absolute accuracy of isotopic measurements is no longer instrumentation hardware. This article discusses how greater understanding and control of the chemistry of sample purification, gravimetric blending of separated isotopes, filament loading, and the physico-chemical processes occurring at the high-temperature filament will be necessary before the advantages of robotic sample preparation and filament loading and automated analysis can be attained. Such improved understanding is seen to be an essential procursor to controlling and reducing the uncertainty in isotopic ratio measurements to one part in 10{sup 5}.
