Environmental & Microplastics
Environmental spectroscopy provides fast, flexible tools for analyzing materials and monitoring changes in our environment. StellarNet UV-VIS, NIR, and Raman spectroscopy systems support applications including water quality and pollution monitoring, soil analysis, algae and vegetation research, chemical analysis, and microplastics identification.
Raman spectroscopy can identify microplastics and polymers through their unique molecular fingerprints, while UV-VIS and NIR spectroscopy enable a wide range of optical and environmental measurements. With compact fiber-optic systems for laboratory, field, and real-time monitoring, StellarNet provides versatile spectroscopy solutions for environmental research and analysis.

Assessing Land Cover and Soil Quality with Remote Sensing
Understanding changes in land cover and soil quality is important for environmental monitoring, agriculture, and land management. This research combines remote sensing, spectroscopy, and geographic information systems (GIS) to assess landscape characteristics and soil conditions, demonstrating how spectral data can provide valuable information across large areas.
Measuring Soil pH with Spectrophotometry
Soil pH is an important indicator of soil health and can influence nutrient availability, plant growth, and agricultural productivity. This research explores a spectrophotometric method for determining soil pH and compares the results with traditional glass electrode measurements, highlighting an alternative approach for analyzing soil extracts.
Advancing Microplastics Detection with Raman Spectroscopy
Microplastics are increasingly found across environmental systems, creating a need for faster and more reliable methods of identifying and analyzing particles. This Earth Day feature explores how Raman spectroscopy and particle analysis can help characterize microplastics, providing detailed chemical information that can support environmental research and monitoring.
