Diode array detector

Article Nr.: ADC11

The next generation of KNAUER DAD detectors begins with the new AZURA DAD 6.1L. It features a novel light path and flow cell architecture with improved handling and excellent performance. The frontal lamp and cell change ensures easy and secure maintenance. The temperature controlled optical bench minimizes signal drift. The wide flow cell selection allows the DAD 6.1L to be easily adapted to your needs. An optional fiber optics adaptor offers the possibility to separate the flow cell spatially from the device and thus provides enhanced security for hazardous, explosive or toxic work processes.

Detektor Azura UVD 2.1S

AZURA_UVD_2.1S_detector

 

Small variable single wavelength

Article Nr.: ADA00

The AZURA UVD 2.1S is a highly competitive single variable wavelength UV detector for HPLC.  It offers excellent technical specifications for routine laboratory work. With its small footprint, it is one of the smallest detectors for HPLC on the market.

The UVD 2.1S comes in the novel small AZURA housing. The installed deuterium lamp covers a wavelength range from 190 to 500 nm. The UV detector can be controlled with OpenLab EZChrom Edition®, ChromGate® and ClarityChrom® software, as well as from the front panel (stand-alone operation), via LAN, via RS-232, or through analog input/output; allowing it to be integrated into almost any LC system.

Detektor ELSD

Detektor ELSDThe Light Scattering Detector ELSD 3300 has a wide range of applications in routine analysis and research. Common fields of application for the ELSD 3300 include the analysis of non-UV active compounds such as: sugars, fats, surfactants, polymers, pharmaceuticals, Amino acids / Peptides, Natural compounds. Three-Step-Principle: 1) Nebulization of the column effluent in nitrogen by means of a jet. 2) Evaporation of the mobile phase in a heated zone leaving a fine mist of sample particles. 3) Detection of the scattered light, when the sample particles pass and interfere the laser light beam. Gradient runs of variable slope and composition can be detected drift free without complicated setup procedures, because vaporization of the mobile phase occurs before detection takes place.
