We request two INTEGRAL observations of 250 ksec each of the bright Seyfert 2 galaxy NGC 2110. Previous observations by BeppoSAX showed a complex X-ray spectrum but did not extend significantly above 100 keV in order to study the continuum and determine the turnover (cut-off) in the hard X-ray band. INTEGRAL offers the unique possibility to study the physics involved in absorbed AGN and even enables us to study the connection between flux variation high-energy cut-off reflection component and iron fluorescence line. The variation in flux over the time of the observation in various energy bands can reveal the geometry of this source. The two separate observations will most likely catch the source in two different states allowing to further constrain the connection between high energy spectrum and reprocessing. Analysing all INTEGRAL data covering NGC 2110 even though being at large off-axis angles led to a 11 sigma (20 - 40 keV) detection in ISGRI within 97 ksec ensuring that this source is indeed bright enough to perform detailed spectral studies.
