Total trans fatty acid analysis in spreadable cheese by capillary zone electrophoresis.

An alternative method for determination of total trans fatty acids expressed as elaidic acid by capillary zone electrophoresis (CZE) under indirect UV detection at 224 nm within an analysis time of 7.5 min was developed. The optimized running electrolyte includes 15.

External polyacrylate-coating as alternative material for preparation of photopolymerized sol-gel monolithic column.

Photopolymerized sol-gel monolithic columns for use in capillary electrochromatography were prepared in 125 microm i.d. polyacrylate-coated fused-silica capillaries.
