Enhanced characterization of SO₂ plume height and column density using the second UV spectral band of TROPOMI [PDF]

Atmospheric Measurement Techniques
Volcanic emissions of sulfur dioxide (SO2) affect the environment, climate, and society. Their detection and quantification rely extensively on remote sensing techniques, which are used to track SO2 and monitor volcanic activity worldwide. In particular,

Descriminant analysis of flowers, leaves, stems of combretum indicum varr.M and Varr.B with UV-vis spectrophotometric chemometric method [PDF]

E3S Web of Conferences, 2023
Combertum indicum has two varieties, namely varr.M and Varr.B., so to maintain the truth of the sample it is necessary to discriminate. The way to distinguish these two varieties can use the UV-vis spectrophotometric approach.

UV-Vis Spectra-Activated Droplet Sorting for Label-Free Chemical Identification and Collection of Droplets.

Analytical Chemistry, 2021
We introduce the UV-vis spectra-activated droplet sorter (UVADS) for high-throughput label-free chemical identification and enzyme screening. In contrast to previous absorbance-based droplet sorters that relied on single-wavelength absorbance in the ...

The VIS detector system of SOXS [PDF]

, 2018
SOXS will be a unique spectroscopic facility for the ESO NTT telescope able to cover the optical and NIR bands thanks to two different arms: the UV-VIS (350-850 nm), and the NIR (800-1800 nm). In this article, we describe the design of the visible camera
