An improved procedure for packing capillaries for capillary electrochromatography

Autor: B. Lumley, T. M. Khong, David Perrett

Publikováno v: Chromatographia. 54:625-628

This paper introduces a novel improvement to high pressure slurry packing of CEC capillaries. Slurry homogeneity is maintained by constantly stirring in a ‘balanced density’ solvent system in a vessel with a configuration that prevents silica agg

The Characterisation of Chemically Bonded Chromatographic Stationary Phases by Thermogravimetry

Autor: T. M. Khong, B. Lumley, David Perrett

Publikováno v: Chromatographia. 60

This paper details a simple thermogravimetric procedure to determine the amount of ligand present on silica based chemically bonded stationary phases for HPLC and CEC. The weight loss observed from stationary phases between 150 and 600 °C was found

Determination of encapsulated menthol flavour using thermal desorption gas chromatography

Autor: M, Staniforth, T M, Khong

Publikováno v: Journal of microencapsulation. 16(3)

The analysis of menthol in encapsulated products is challenging due to the nature of the encapsulating matrices and the volatility of the analyte. Normal sampling/extraction procedures cannot be applied to the different types of menthol encapsulated

Novel method for the preparation of chemically bonded phases and studies of their chromatographic performance

Autor: T. M. Khong, C. F. Simpson

Publikováno v: Chromatographia. 24:385-394

This paper describes a novel process for the production of chemically bonded phases using fluidised bed technology. Hitherto fluidisation of particles with the size range below 50 µm was considered impossible. In this study, particles with sizes as
