FOCUS

On the cover. O n - c o l u m n sample c o n c e n t r a t i o n u s i n g field amplified CZE. CZE is a major separation technique for the analysis of small volumes. To achieve high resolution in CZE, the width of the analyte zone must be very small. Ring-Ling Chien and Dean S. Burgi of Varian Associates discuss the mechanisms and applications of sample stacking in continuous buffer systems, emphasizing on-column concentration
INSTRUMENTATION
476 A
Chromatography/FT-IR spectrometry a p p r o a c h e s to analysis. In the past several years, significant progress has been made in the powerful analytical scheme of chromatography combined with FT-IR. Chuzo Fujimoto and Kiyokatsu Jinno of the Toyohashi University of Technology review the c u r r e n t s t a t u s a n d discuss flow-cell and mobile-phase elimination methods
