ATP synthase motor - brilliant design by the master designer

The labs themselves will say that it’s contamination. There is no possible means to completely eliminate contamination, especially for something as ubiquitous as carbon.

Given that I can find multiple instances on this forum, you have:

Well, in the specific cases that I was referencing, it’s relatively easy–the chemical structure of the mineral crystals being analyzed actively excludes the daughter isotope, so we can confidently conclude that it was almost zero; that only requires lab measurements and no changes to fundamental properties.

Given that lots of different independent measurements can be taken, and they agree with each other well in most cases, this can be calibrated for. Or, in some cases, it’s relatively easy to exclude these possibilities given the mineral properties.

Given that both air and the equipment used for the analysis contain or have been in contact with more modern sources of carbon, no, there is no way to completely eliminate contamination. The dates that I have seen obtained for diamonds are well beyond the limits of when the method works well, and in any case are completely incompatible with an age of 6,000 years. There is also the issue of instruments not having perfect precision.
