Thermo Fisher Scientific Catalysts characterization TPDRO 1100 system

The TPDRO 1100 is a new concept instrument designed for the characterization of heterogeneous supported catalysts and reactive solids. TPDRO 1100 offers full automation by absolute computer control and high accuracy detection. It is the ideal solution for quality control and research applications.

The most common measurements for catalysts characterization as TPD, TPR, TPO, pulse chemisorption ( to study metal surface area , metal dispersion, acid/base sits concentration and activation energy ) & Single Point Flow BET are now easy to be performed and completely unattended by the new TPDRO 1100. The detector is a TCD type (dynamic flow method), which makes this instrument extremely sensitive, providing the solution for a large range of linearity.

To carry out more comprehensive investigation of temperature (surface) reactions, a suitable mass spectrometer( In sequence to the TCD detector) can be connected to the TPDRO. The advantage is that the MS provides information of the gaseous species evolving from the catalyst, permitting both a qualitative and quantitative determination.

Thanks to the new designed reactors (Proprietary design reactors), the user can perform suitable catalyst activation in the preparation position while the analysis on a different sample is running. The software runs under Windows 2000/XP and features a useful mix of different databases for samples, gases, metals, reactions, analytical methods, calibration run, etc.

Mode of operation
Parallel (two reactors upto 1100 ^oC): two independent sample positions (two ovens), for catalyst activation (pre-treatment) and for analysis (TPD, TPR, TPO or pulse chemisorption). The two positions are interchangeable.
Sequential (one reactor upto 1100 ^oC): unlimited and unattended sequence of operations are possible on a single reactor (i.e. multiple reduction, oxidation, chemisorption, desorption, etc,)
Pulse Chemisorption (upto 1100 ^oC ): with Pulse gas loop flow: fixed, about 30 cc/min and Pulse gas type: H2, O2, CO2, CO, air, mixed gases (i.e. H2 in Ar, O2 in He), vapors mixed in He, light corrosive gases (i.e. NH3 in He).
