The Evaporative Lightscattering Detector ZAM 3000 is an universal detector for HPLC. It is used to analyze components which don‘t have UV absorption, cannot be separated with an isocratic solvent and must use a gradient elution, which can‘t be  used with a Refractive Index  Detector. Only mobile phases without any buffers should be used.
  
In comparison to other ELSD detectors, the ZAM 3000 consists of a rotation chamber with a nebulisation and a drying section made from glass.  
The chamber can be easily removed from the instrument and cleaned.

Description of operation:
The solvent containing the components is nebulized into aerosols and sprayed into the rotationchamber at a given angle. In doing so, there is a selection between smaller and larger aerosols, at which the larger ones are flowing along the wall to a waste outlet and the smaller aerosols are picked up by an additional gas (which can be heated) and forced within a rotary movement, where the aerosols are dried. The amount of additional gas, which is  set by a flowcontroller, determines the drying time of the aerosols. This is a new Method (Patent pending) to optimize the handling of the Aerosols and the work within a low temperature mode.
