Because geochronologists want to measure isotopes with different masses, a mass spectrometer works really well for dating things.

I do think that radiometric dating is an accurate way to date the earth, although I am a geochronologist so I have my biases.

Until this century, relative dating was the only technique for identifying the age of a truly ancient object.

By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.

Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content.Carbon-14 is also passed onto the animals that eat those plants.After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.The process of radiogenic dating is usually done using some sort of mass spectrometer.A mass spectrometer is an instrument that separates atoms based on their mass.
