Some experimental observations of liquid matrix effects in organic sims
At incident current densities on the order of 10−5A/cm2, a period of ∼1–30 s has been observed for nearly constant secondary ion emission to be established from glycerol sample matrices following the onset of sample irradiation with low energy (∼5–7 keV) metal ions. It is further observed that after prolonged irradiation the intensities of the molecular ions of certain compounds increase significantly shortly before the glycerol is depleted. Further study of these effects may assist in elucidating certain aspects of the matrix's role in the process of particle induced secondary ion emission from liquid samples.
