Additional advantages of the single isotopic measurements of the K.
J value uncertainty can be minimized by constraining the geometry of the standard relative to the unknown, both vertically and horizontally.
In order for an age to be calculated by the Ar technique, the J parameter must be known.
For the J to be determined, a standard of known age must be irradiated with the samples of unknown age.
Multiple argon extractions can be performed on a sample in several ways.
Step-heating is the most common way and involves either a furnace or a laser to uniformily heat the sample to evolve argon.
