Increasing productivity while maintaining or improving data quality and security is one of the most important objectives of today's analytical laboratories. To meet this objective Agilent has developed the industry-first sub-two micron particle columns (Zorbax 1.8um RRHT) and the 1100 Series Ultra-fast LC system, which facilitates injection-to-injection cycle times of less than 1 minute, analysis times less than 30 seconds and peak widths smaller than 1 second.
However, current diode-array UV detectors with 20 Hz signal sampling rate and 10 Hz spectral rate are simply not fast enough to accurately measure chromatographic peaks narrower than 1 second as delivered ...
