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.This imprecision (and inaccuracy) is transferred to the secondary minerals used daily by the Ar age equation will become continually more refined allowing much more accurate and precise ages to be determined.Because the J value is extrapolated from a standard to an unknown, the accuracy and precision on that J value is critical.The quantity of potassium in a rock or mineral is variable proportional to the amount of silica present.Therefore, mafic rocks and minerals often contain less potassium than an equal amount of silicic rock or mineral.Argon can mobilized into or out of a rock or mineral through alteration Ar and potassium, there is not a reliable way to determine if the assumptions are valid.

In order for an age to be calculated by the Ar technique, the J parameter must be known.

The monitoring of the interfering reactions is performed through the use of laboratory salts and glasses.
