A13C isotope distillation separation plant was used to search for naturally-occurring superheavy isotopes. Superheavy (X−) isotopes of carbon in CO would be only slightly less volatile than the normal 12C16O. Over 100,000 mol CO were passed through

A process has been developed to provide isotopic feed to a nitric oxide isotope distillation plant. Central to the process is the isotopic chemical exchange of NO and nitric acid in countercurrent flows in a 3-in. diameter packed column. An isotopica

This isotope separating plant has a great height with many long columns in parallel, low process flows compared with its boil-up, and a long time response. All these features result from dealing with a mixture whose separation factor is near unity, t

A diffusion method that requires less labor than distillation methods was developed for preparing soil KCl extracts for 15NH+4 and 15NO-3 analyses. The procedure is ideal for preparing samples having low N mass (50–200 µg N) with no cross contamin

The theory of the hot‐wire thermal‐diffusion column as developed by Jones and Furry involves the shape factors h, kc, and kd, which are functions of the transport properties of the gas. The shape factors have been evaluated numerically for a gas

A further experimental study has been made of the efficiency of separation of ${\mathrm{He}}^{3}$ from mixtures of ${\mathrm{He}}^{3}$ and ${\mathrm{He}}^{4}$ in a method making use of the "internal convection" process in superfluid liquid helium. It

After ingestion of galactose (10 g per m2) labeled with 14C or 13C, breath was collected from subjects at intervals for 4 hr followed by measurement of 14CO2 by liquid scintillation counting or of 13CO2 by mass spectrometry. Nine subjects without liv
