Hiden - Model CATLAB-FB - Combined Furnace and Mass Spectrometer System for Catalyst Core Quantification
From Products for Catalysis and Thermal Analysis
The CATLAB-FB is a combined furnace and mass spectrometer system for the analysis of catalyst core specimens at temperatures up to 1000°C, with multi-stream gas/vapour flow control and mass spectral analysis of both feed and downstream gases.
Overview
The furnace houses a horizontal quartz reactor tube with in-bed thermocouple for optimum thermal precision, a standard internal diameter of 26 mm and a uniform central hot-zone of 150 mm. The furnace is programmable from 50°C through to 1000°C at a fastest ramp rate of 20°C/minute. The system has capacity for up to 12 mass flow controlled gas streams, selectable with flow rates from 0.1-10 L/minute and for operation with corrosive feed gases.
Options also includes a pulse chemisorption (PCS) mode for injection of sorbates to the reactor and a vapour feed system to enable vapour reaction characterisation in both PCS and continuous flow modes. All system elements are programmable from the integrated control program together with mass spectrometer data acquisition, data display and data interpretation.
There is also the possibility that a customer supplied furnace can be integrated into the CATLAB-FB set-up.
