• bombardment
  • Upon Ga(+) bombardment, the maximum PS fingerprint ion yields are obtained using a monolayer spin-coated on gold, whereas for C(60)(+), the best results are obtained with at least one monolayer, irrespective of the substrate and without any other treatment. (uclouvain.be)
  • biological
  • Because mass spectrometry is performed in high vacuum, it is essential to preserve the lateral organization of the sample while removing bulk water, and this has been a major barrier for applications to biological systems. (osti.gov)
