The Analytical Laboratory has a dedicated 4-member Team to provide analytical and material characterization services to the Department of Chemical Engineering, other departments at UCT, as well as other Universities and small-medium companies. As such, the Analytical Team has experience with analysing a variety of samples, particularly those with complex matrices. The Analytical Team is also responsible for co-ordinating waste disposal for research groups and labs in the department.
Varian 730ES ICP-OES and Agilent 4200 MP-AES
These instruments are used for the quantification of metals in solution. Solid samples are digested prior to analysis. Majority of the periodic elements can be analyzed except halides, inert gasses and C, H, N; O.
CEM-MARS 6 microwave digester
The microwave digester is used for the acid digestion of samples such as catalysts, mineral ores, coals and other materials.
TA AR1500ex Rheometer
The rheometer can be used to measure the stress, strain and other rheological properties of a variety of materials.
Malvern Mastersizer 2000 and Malvern Zetasizer Nano ZS
The Mastersizer is used to determine the particle size distribution of powders between 0.2 – 2000 µm. The Zetasizer is used to measure particle size and zeta potential of particles between 0.3 nm – 10 µm.
Micromeritics Tristar II 3020
The Tristar is used for nitrogen physisorption studies to measure the BET surface area of mesoporous materials. These materials should ideally contain mesopores in the range 2-50 nm.
The ASAP unit is used for chemical adsorption studies on catalysts. It is mainly used to determine the metal surface area, using gases such as H2, CO and O2
Autochem 2950 and 2920
Predominantly used to study the surface properties of catalysts. The instruments are used for temperature-programmed studies (TPX), such as reduction (TPR), oxidation (TPO), desorption (TPD).
