Argon-38 Calibration Gas
Argon-38 calibration gas is a stable isotope of argon, a rare gas, mixed at trace levels in a 1-liter cylinder for mass spectrometry calibration. It qualifies as a separate chemical element under Chapter 28, as it is not a radioactive isotope and falls under the 'other' rare gases category.
Helium-3 Research Gas
Helium-3 research gas is an isotopically separated rare gas used in neutron detection and low-temperature physics. Although helium has a specific subheading, helium-3 is classified under 'other' rare gases because it is an isotope not covered by the standard helium subheading.
