ECCN 3A233
NPATMass spectrometers, capable of measuring ions of 230 u or greater and having a resolution of better than 2 parts in 230, and ion sources therefor, excluding items that are subject to the export licensing authority of the Nuclear Regulatory Commission (see 10 CFR part 110).
What This ECCN Covers
ECCN 3A233 controls mass spectrometers capable of measuring ions of 230 atomic mass units or greater and having the resolution in the entry, and ion sources therefor. These instruments can measure heavy isotopes relevant to the nuclear fuel cycle and are controlled for Nuclear Nonproliferation and Anti-Terrorism reasons.
Who needs to check this?
Suppliers of high-mass-range mass spectrometers and the analytical labs that use them.
Compliance tip
Control turns on the mass range, resolution, and source type in the entry — many analytical mass spectrometers fall outside. With NP among the reasons, apply Part 744 nuclear end-use diligence and verify the Country Chart.
Items Covered
- a.Inductively coupled plasma mass spectrometers (ICP/MS);
- b.Glow discharge mass spectrometers (GDMS);
- c.Thermal ionization mass spectrometers (TIMS);
- d.Electron bombardment mass spectrometers having both of the following features:
- 1. A molecular beam inlet system that injects a collimated beam of analyte molecules into a region of the ion source where the molecules are ionized by an electron beam; and
- 2. One or more cold traps that can be cooled to a temperature of 193 K (−80 °C) or less in order to trap analyte molecules that are not ionized by the electron beam;
- e.Mass spectrometers equipped with a microfluorination ion source designed for actinides or actinide fluorides.
Control Reasons
Items controlled for nuclear nonproliferation reasons.
Items controlled for anti-terrorism reasons. Most items on the CCL have AT controls.
