ESA Analytical Chromatographic detection to Zeptomole (10 -21) levels

7th OCTOBER 2002. Available from ESA Analytical Ltd. the ZETALIF Laser Induced Fluorescence detector provides research scientists with the ability to monitor HPLC and Capillary Electrophoresis eluants down to unprecedented detection levels.

Offering sensitivity typically 100-1000 times that of traditional fluorescence detection, ZETALIF opens the door to new and demanding applications in pharmacology, neuroscience, molecular biology, toxicology and environmental trace analysis.  The use of highly monochromatic laser sources in the ZETALIF provides the selectivity to detect trace levels of compounds of interest even in complex matrices.

Modular in design the ZETALIF can be connected to virtually any HPLC, micro-HPLC, Capillary LC, Capillary Electrophoresis or CEC system.  A simple, robust optical design, which excludes moving parts, ensures high reliability.  Contrary to conventional fluorescence detectors, the unique flow cell design and the use of stable laser sources instead of conventional monochromators in the ZETALIF means it rarely needs recalibration. 

ZETALIF detectors provide the ultimate in detection sensitivity and may incorporate a broad selection of lasers operating from the deep UV through to the infrared.   With fourteen available operational  wavelengths  ranging  from 266nm to 785 nm the versatile ZETALIF can work with both natively fluorescent and derivatised molecules.   Offering measurement over a linear dynamic range of 3-4 orders of magnitude the ZETALIF may be easily operated by anyone with a basic understanding of Capillary Electrophoresis or HPLC.

ZETALIF detectors are fully compliant with all safety rules and CE requirements.
