Technical Specifications of
the TPDRO 1100
The most common measurements for catalysts
characterization as TPD, TPR, TPO and Pulse chemisorption are now
easy to be performed and completely unattended by the new TPDRO 1100.
The detector is a TCD type, extremely sensitive and showing a very
large range of linearity. The TPDRO can automatically perform sample
pretreatment simultaneously to the analysis on two separate and independent
ports. Thank to the new designed sample holder, 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 95/NT, and features a useful mix of up to seven different
databases for samples, gases, metals, reactions, gas mixtures, analytical
methods and calibration run.
Analytical capacity
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.
