Not much more though — just about two neutrons more since Carbon 12 and Carbon 14 differ by the addition of two neutrons in the later. To measure the amount of C12 and C14 we need to separate them, which is where a mass spectrometer comes in. Because of their slightly different masses, they go to different places on the mass spectrometer. Mass spectrometers are like big black boxes to kids and most adults. We were searching and searching for a fun hands-on way to learn about carbon dating when this idea popped into Dr.
Editage Insights. However, the process can take up to several weeks as there are only about facilities in the world that have spectrometers. Researchers from Istituto Nazionale di Ottica INO in Italy have devised a new approach called saturated-absorption cavity ring-down SCAR that can cut down on the time and expense it takes to carbon date samples. Apart from providing results within two hours, the new instrument is also portable. The researchers are further honing their technique and exploring new applications for their instrument.

Seventy years ago, American chemist Willard Libby devised an ingenious method for dating organic materials. His technique, known as carbon dating, revolutionized the field of archaeology. Now researchers could accurately calculate the age of any object made of organic materials by observing how much of a certain form of carbon remained, and then calculating backwards to determine when the plant or animal that the material came from had died.
The most important archaeological dating method is radiocarbon dating. It is a technique that can yield absolute dates with accuracy up to approximately years before present. However its application has caused extreme confusion and misunderstanding of the archaeological record.
