Getting a pure sample for AMS to count is critical to obtaining a precise absolute date, the prize target for radiocarbon scientists.
In the February Chemical Reviews, Ann McNichol, Eglington Eglington's colleague at Woods Hole, reported that compound-specific dat ing could not only help refine radiocarbon dates but also contribute to pinning down past carbon cycles.
RINGS OF TIME What scientists are really holding out for is tree ring data that calibrate absolute radiocarbon dates back to 60,000 years.
