  We investigate the chemical freeze-out in heavy-ion collisions (HICs) and the
impact of the hadronic spectrum on thermal model analyses. Detailed knowledge
of the hadronic spectrum is still an open question, which has phenomenological
consequences on the study of HICs. By varying the number of resonances included
in Hadron Resonance Gas (HRG) Model calculations, we can shed light on which
particles may be produced. Furthermore, we study the influence of the number of
states on the so-called two flavor freeze-out scenario, in which strange and
light particles can freeze-out separately. We consider results for the chemical
freeze-out parameters obtained from thermal model fits and from calculating
net-particle fluctuations. We will show the effect of using one global
temperature to fit all particles and alternatively, allowing particles with and
without strange quarks to freeze-out separately.
