HPLC detectors

UV-VIS LCD 5000

This detector is designed for analytical and preparative HPLC. Light source consisting of deuterium and halogen lamp and monochromator, provides setting of variable wavelengths in the range 190-700nm. LCD 5000 is a detector with high precision and reproducibility of the wavelength, with low noise and drift. Replacing of the standard analytical cell, it can be suitable for preparative chromatography, and also of the micro column chromatography. It is also used for measuring of the absorbance in a flow cell wherever it is possible to suck the sample into the cuvette and measure the absorbance, both at one wavelength and in the partial spectrum. This detector is fully controllable by freeware CHROMuLAN or commercial software Clarity.

ELSD LCE 5000

This universal detector is constructed so that all parts in contact with the sample are completely bio-inert - glass and PTFE. These materials are also resistant to most conventional solvents, easy to clean and eventual source of contamination in them can be found easily. This detector is fully controllable by commercial software Clarity.
