Instead, the ratios of the different argon isotopes are measured, yielding more precise and accurate results.

Argon loss and excess argon are two common problems that may cause erroneous ages to be determined.Potassium can be mobilized into or out of a rock or mineral through alteration processes.Due to the relatively heavy atomic weight of potassium, insignificant fractionation of the different potassium isotopes occurs.Ca F is also routinely irradiated and measured to determine the Ar technique relies on ratios instead of absolute quantities, we are able to extract and measure multiple aliquots of argon from a single sample.

Multiple argon extractions can be performed on a sample in several ways.The monitoring of the interfering reactions is performed through the use of laboratory salts and glasses.
