Chiraldetector ALP

   Unique: This detector requires 
   no chromophores!


This Chiraldetector was developed for the detection of enantiomers and measures the real-time rotation of optically active substances by means of a linearly polarized, 670 nm laser beam with micro-degree resolution. In comparison to other chiral detectors, the ALP has the advantage of being able to detect compounds without chromophores. For HPLC, SFC and SMBC.

Function principle

Light, including laser light, vibrates at many levels. If it is sent through an optical, polarizing filter, however, it forms a beam of light that only vibrates on one level. The resulting energy is called linearly polarized light.

Optical activity is defined as the capability of a compound to turn linearly polarized light in one direction or another. Enantiomers are chemically identical, but differ in their molecular geometry, leading to a similar but counter-directional rotation of the polarized laser light.

The PDR chiral polarimeter determines both the peak area and the direction of the optical rotation.
