The model DT1826 is a tunnel diode detector that is offered with either negative or positive output polarity.
Units use "Smart Beam" X-ray tube technology and a high resolution Si PiN diode detector that eliminates radioactive isotopes found in most other units.
Oxford's patented proportional counter provides better sensitivity for elements of low atomic number, while the PIN diode detector provides better analysis of heavy metals.
A possibility for future experiments is to determine if the incredibly sensitive Zener diode detector effect can directly detect primordial gravitational waves from the inflation epoch, 3-space turbulence, as a background to the local galactic 3-space flow effects.
