Krüss Optronic GmbH sets new standards in the high-speed measurement polarimetry. By polarimetry the optical activity of a substance is determined. That is a relatively rare characteristic - most liquids and solids aren't optically active.

Polarimeters thus are suitable to examine solutions for very specific components. An important use of polarimeters is the determination of the sugar content in food industry. Another typical application area is the pharmaceutical industry, which uses polarimeters for purity controls of its substances. The polarimeter P8000 is perfectly suitable for these applications, especially as it provides measuring results faster than ever before. The measurement results are availale in only 1 second, independently of the angle of rotation. Also a high angle of rotation is measured within 1 second. This is unique within polarimetry.

The new Model P8000-Series Polarimeters from A. Krüss Optronic is characterized by excellent measurement speed over their entire range. A special measuring method provides continuously calculated analytical results at a measuring time down to one second. Additional benefits include the easy-to-use touch screen and a clearly-arranged readout of all important measuring data.

Data output is GLP compliant due to USB and RS232 interface, user administration and all setting options for comprehensive sample identification.

P8000-Series Polarimeters have a measurement range of ±90°, ±259°Z or 0 to 99.9 g/ml with resolution of 0.001°, 0.01°Z and 0.1 g/ml respectively. Cell lengths up to 200mm length can be accommodated.

VoltammetryVoltammetry is a sensitive analytical technique for elemental detection. In a voltammeter the current is measured in the system whilst the voltage is varied. Usually 3 metal electrodes are required including the reference, auxiliary and working electrodes. In polarography, a subclass of voltammetry, the working electrode used is a dropping mercury electrode (DME). The 2 main types of voltammetry are cyclic and linear sweep voltammetry.InterferometryInterferometry is an investigative technique used to analyze the pattern of interference created during the superposition of 2 or more waves. An interferometer is used to produce 2 or more overlapping waves. The interferometer is comprised of 2 or more telescopes, a detector and a correlator. The interferometer detector may utilize homodyne or heterodyne detection of the interference pattern.
