[Seavox] FW: L05

[Moncoiffe, Gwenaelle]

Dear All,

We are planning to add the following 2 new instrument categories to L05. Let me know by end of the week if there are any issues.

PREF TERM       ALT TERM        DESCRIPTION
Thermal ionisation mass spectrometers   TIMS    Instruments that measure isotopic ratios using thermal ionisation. Purified samples are heated to cause ionisation of atoms. Subsequently, ions are focused into a beam by an electromagnet and then separated into individual beams based on their mass/charge ratio.
Isotope ratio mass spectrometers        IRMS    Instruments that measure isotopic ratios using an electron ionisation source. Atoms in purified samples are ionised using a beam of electrons under vacuum. Subsequently, ions are focused into a beam by an electromagnet and then separated into individual beams based on their mass/charge ratio.


Many thanks and best regards,

Gwen.
