For more than 20 years, LLA Instruments GmbH (LLA) develops and manufactures analytical technology for chemical imaging in process and laboratory usage. NIR spectrometer by LLA are utilised worldwide for the analysis and sorting of material streams e.g. waste separation in recycling. LLA technology enables the identification of PVC in PET-flakes sorting or identification of extraneous material in paper recycling at maximum efficiency. In addition, the imaging NIR spectrometers are also used in C & D recycling, minerals and food sorting. The NIR portfolio includes hyperspectral cameras as well as multiplexed NIR spectrometers. Further accessories such as illumination units, software package, RGB line scan camera and comprehensive support complete the NIR portfolio of LLA. The rugged product design is ideally suited for use in harsh environmental conditions. For standard applications, LLA provides ready-to-use analysis routines. Based on LLA's longtime experience, further applications can be developed and customised for new sensor-based sorting applications. The high-resolution Echelle spectrometer ESA 4000 was developed for the in-situ analysis of inorganic matter e.g. metal and glass and is used in high profile research projects.
