Systematic Identification of MicroPLastics in the Environment

Developed by Aalborg University, Denmark and Alfred Wegener Institute, Germany

siMPle is a freeware for the fast detection of microplatic materials in environmental samples. Its algorithm compares the IR spectra of the sample with each reference spectra in the database, then assigns a material to them along with a probability score.

The program is developed at Aalborg University, Denmark, in collaboration with the Alfred Wegener Institute in Germany.

The software, its previous version, and the reference database can be downloaded on this page. There´s also included a small sample database for trying the software.

A step-by-step guide for the use of the software can be found on the following page:
