TPDRO 1100

Thermo Scientific* TPDRO 1100 is a time-saving, high precision instrument designed for the characterization of heterogeneous supported catalysts and reactive solids. TPDRO performs automatically and simultaneously the sample preparation (activation) on a reactor while analyzing another sample in a second reactor, thus saving valuable lab time.
The TPDRO 1100 performs automatically in parallel on two reactors or sequentially on a single one, the catalyst preparation (like oxidation, reduction, saturation with a probe gas, degassing, etc.) and surface reactivity characterization (temperature programmed desorption, reduction and oxidation, chemisorption by pulses of gases and vapors). Thanks to its double and independent pneumatic circuits, TPDRO shortens the total process saving valuable lab time. TPDRO is particularly suitable in industrial catalysis research labs where a high sample throughput is required without compromising accuracy. TPDRO 1100 provides easily and rapidly information like catalyst metal dispersion, metal surface area, metal aggregate size, activation energy, single point BET, acid and basic sites surface concentration.

The "heart" of the TPDRO 1100 system is a special reactor that can be sealed from the external environment. Catalysts, after the activation, can be stored without time limits under a suitable inert gas atmosphere. The complete closed reactor with the sample can thus be transferred without compromising the activated catalyst surface.  The pretreatment and the experiments of TPD,TPR, TPO and Pulse chemisorption can be performed from –70°C up to 1100°C with temperature rates ranging from 1 to 40°C/min (depending on the maximum selected temperature). TPDRO 1100 mounts a four tungsten or gold plated filaments HWD (Hot Wire Detector). The HWD diffusion cell is maintained at constant temperature to assure unmatched stability and reduced signal drift. In addition, the reactor waste port of TPDRO can be interfaced with a suitable mass spectrometer to extend the quality of information on the effluent gas composition.

  • Special design, flow through quartz reactor can be sealed from external environment
  • The catalyst, after the activation process, can be stored without time limits under a suitable inert gas atmosphere or transferred without contamination
  • Two independent reactors, one used for catalyst pre-treatment and the other for analysis, use two independent circuits and heating systems thus saving valuable lab time
  • A thin thermocouple, protected by a quartz shield, can be placed inside the catalyst bed to detect exothermic or endothermic reactions
  • TPDRO 1100 can work with unlimited sequences of preparation and analyses, in parallel or sequential modes, individually stored under a different filenames
  • TPDRO 1100 can work with vapors or with cryogenic temperatures using special upgrade kits
  • Dedicated software controls the activation steps and the analytical cycle in real time and features advanced routines for data processing (baseline subtraction, peaks automatic or manual integration, reporting and main calculations on metal surface area, metal dispersion, etc.)
Includes:
  • Two complete reactors
  • Type K thermocouple 0.5mm diameter with quartz shield
  • Various adsorbent materials to remove water vapor from carrier before the detector
  • Stainless steel and copper cold trap to remove vapors from the carrier gas
  • Two antimagnetic tubular ovens, working up to 1100°C, can be cooled down to -70°C
  • Serpentine device to maintain the reactor at constant temperature for pulse chemisorption (must be connected to a suitable recirculation bath not enclosed)
  • Acquisition data processing software and PCB interface
  • Instruction manuals

Compatible with:
  • Kit Vapor generator for TPDRO 1100
  • Kit Cryo for TPDRO 1100
