Elemental characterization of ionizer filaments for thermal ionization mass spectrometry (TIMS).


EMSL Project ID
19593

Abstract

There has been a great discrepancy in the function of ionizer filaments for use in TIMS in our lab. Seemingly identicle preparation methods continue to give unpredictable results. This proposal seeks to utilize the TOF-SIMS at EMSL to characterize and compare TIMS ionizer filaments with the objective of identifying chemical signatures of contaminents that degrade functionality.
