Radiometric dating • actually a simple technique • only two measurements are needed: • 1 the parent:daughter ratio measured with a mass spectrometer • 2 the decay constant measured by a.
A mass spectrometer is an instrument that uses a series of magnets to bend a beam of ions and then physically count how many there are, so with ams radiocarbon dating, we can measure a. Limit of the technique is reached (beyond this time, other radiometric techniques must be used for dating) by measuring the 14c concentration or residual radioactivity of a sample whose age.

A mass spectrometer is a fundamental device in any radiometric dating experiment mass spectrometers can be used to measure isotopic samples as small as one 1 nanogram mass spectrometers. Accelerator mass spectrometry also takes less time to analyze samples for carbon 14 content compared to radiometric dating methods that can take one or two days an accelerator mass.
For the vast majority of radiometric dating methods, the basic instrument that is used is the mass spectrometer mass spectrometers take samples, separate them by mass into constituent.
