Feldspar melts at a higher temperature than biotite or hornblende and lacks structural volatiles which act to flush Ar from a viscous melt.
Thus, even for extractions at 1670° C for 40 min., a small but measurable amount (usually less than 2% of total) remains behind.
A new dedicated low volume Noble Gas extraction line capable of collecting and cleaning the gas extracted from a variety of samples, using a Photon Machine CO2 laser capable of delivering a homogenous laser beam of up to 6mm wide, is attached to the ARGUS VI mass spectrometer.

Their second advantage is the ability to measure the 36Ar on the CDD multiplier while other masses are measured on the faraday detectors, resulting in analytical precision one order of magnitude better than with previous generation instruments.

This isotope of argon is quite unstable, having a half-life of only 269 years.
Consequently, the amount of it found in rocks is negligible — unless you subject them to an artificial neutron source.
The Ar technique can be applied to any rocks and minerals that contain K (e.g. method is also used to date a myriad of other geological events such as volcanism, tectonic plate movements, mountain building rates, sediment formation, weathering and erosion, hydrothermal fluid movements, and alteration and diagenesis of minerals. The main advantage of Ar-Ar dating is that it allows much smaller samples to be dated, and more age and composition (e.g.
Ca/K) information can be obtained from each sample.

Their first advantage is a better sensitivity of the new generation of CDD electron multipliers and 10^12-ohm resistor faraday collectors.
