Absolute independency of sample pre-knowledge and optical properties

Laser Channel - High Resolution & Accuracy

The DIPA 2000 Laser Channel is a straight-forward technique for determining micro-particle size distribution (0.1 - 3,600 microns), without any assumptions or sample pre-knowledge.

This unique analytical technique is called “Laser Obscuration Time” (LOT).

The major advantage of direct particle size measurement over other laser used techniques is its higher resolution obtained by the individual particle measurement approach that allows minor fraction detection and better measurement accuracy.

Main benefit of using the LOT is that the analysis results aren’t affected by any physical or chemical property of the particle or its medium, enabling reliable and “assumptions free” results.

State-Of-The-Art software analyses the obscuration time as multiple pulses algorithm complex,providing within seconds clear and accurate particles size distribution results.

The DIPA 2000 real time sample visualization capabilities efficiently allow its users to easily monitor sample preparation procedures or contamination presence, and by that eliminating

unwanted analytical results due to irrelevant and/or unwanted fractions in the sample:“SEEING IS BELIEVING”.

Software Features

The comprehensive information that is generated by laser and video analysis is easily accessible by intuitive data output software.

Data comparison is made easy by the data mining features, which allows overlay graphs and comparison tables to be compiled.

Real images of the measured particles can be easily saved and printed separately or added directly into the analysis report document.
