This technique looks very interesting, but it is still in its early stages of development. It should allow much smaller sample sizes than at present with AMS.
A sample will still need to be chemically cleaned, processed, and put into an ion source. The process and ion source background levels should be about the same as with AMS. So this new technique probably won't allow us to date older samples than at present.
I suspect the main application of this technique will be to open up dating possibilities with new isotopes which are very difficult to measure at present.

"Science without religion is lame, religion without science is blind." — Albert Einstein
I am very astonished that the scientific picture of the real world around me is very deficient. It gives us a lot of factual information, puts all of our experience in a magnificently consistent order, but it is ghastly silent about all and sundry that is really near to our heart, that really matters to us. It cannot tell us a word about red and blue, bitter and sweet, physical pain and physical delight; it knows nothing of beautiful and ugly, good or bad, God and eternity. Science sometimes pretends to answer questions in these domains, but the answers are very often so silly that we are not inclined to take them seriously. — Erwin Schroedinger
