Notes:
This study comparts signal enhancement and efficiency in CZK employing three modes of detection: the sleeve cell (a simple method for creating a region of extended path length for absorption detection), the bubble cell (extended light path capillaries), and on-column detection in 75 μm i.d. capillary. Flow profile in the sleeve cell was monitored under a microscope. An abrupt change in capillary diameter in the sleeve cell region (from 50 μm to 220 μm) did not produce extensive band broadening. The sleeve-cell detection arrangement delivered a 3.5 fold increase in corrected peak area when compared with an oil-column detection in 75 μm i.d. column.
