Luminar 4030 Free Space Analyzer


The Luminar 4030 Free Space analyzer with miniaturized electronics can be directly connected into the production line for non-contact, nondestructive measurements of chemical and physical properties of powders, solids, suspensions, gels, etc, in diffuse reflectance mode. It can be fan-cooled or vortex-cooled with an internal heat exchanger.

The Luminar 4030’s rugged design and solid-state technology offer a variety of solutions for real-time process applications. This versatile instrument can also be placed into a vast variety of housings to match process area needs. The lightweight unit can easily be transferred among measuring points. Common applications include blenders, dryers, etc.

Often the manufacture of a dosage form requires homogeneous blending of the active component with the excipients. The Luminar 4030 AOTF-NIR Free Space spectrometer allows for fast scanning using no moving parts and without the need to recalibrate the system. Having no moving parts is very important in the blending operation because the analyzer will be mounted on the blender with a battery pack.
