Isotopic

"No error is possible in isotopic readings," he told the AP. ❋ Unknown (2006)

The fingerprint is the result of a natural phenomenon called isotopic fractionation, in which different isotopes (atoms with different numbers of neutrons) of mercury react to form new compounds at slightly different rates. ❋ BJS (2010)

And adding that there is some recent methane growth, but attributable to wetlands, depends upon isotopic analysis. ❋ Nathan Currier (2012)

But while some things give very clear isotopic signals, deciphering others is an art. ❋ Nathan Currier (2012)

Indeed, discussing the isotopic signatures of different ESAS methane, leading ESAS researcher Natalia Shakhova said recently,"It is incorrect to say that anyone is able to trace that signal yet." ❋ Nathan Currier (2012)

The trainees will have an opportunity to learn these techniques, which include spectrophotometric, fluorescent, and radioisotopic enzyme assays and metabolic flux measurement using isotopic tracers. ❋ Unknown (2010)

As an individual's teeth complete their formation by age 12-14 or so, they essentially lock in the isotopic information for the area where that person grew up. ❋ Megan Smolenyak (2011)

Simultaneously, they would examine the isotopic characteristics of the water seeing if some of the hydrogen had an extra neutron and would search for other hydrocarbons related to methane. ❋ Marc Kaufman (2011)

The producers soon narrowed the original list of 16 down to six based on isotopic testing that had been done on the remains. ❋ Megan Smolenyak (2011)

Not being a scientist, I can't vouch for the accuracy of isotopic testing, but if it's true that both men originated in Europe, I think it might be necessary to add one more to the list of candidates: William Bryan. ❋ Megan Smolenyak (2011)

Walker had determined the crystal structure of ATP synthase, and this structure confirmed a mechanism earlier proposed by Boyer, mainly on the basis of isotopic studies. ❋ Unknown (2010)

Where uranium uptake into teeth was significant, an approach combining ESR and 230Th/234U isotopic analysis also yields excellent ages. ❋ Unknown (2009)

However, there is also the isotopic evidence that Jim mentioned earlier. ❋ Unknown (2009)
