The aim of this study was to evaluate the benefits of the simultaneous use of two different analytical methods, namely Fourier transform infrared spectroscopy (FTIR) and mass spectrometry (MS), for online analysis of environmental and process samples

We have analyzed the properties of dust in the high galactic latitude translucent cloud Lynds 1780 using ISOPHOT maps at 100 and 200 micrometers and raster scans at 60, 80, 100, 120, 150 and 200 micrometers. In far-infrared (FIR) emission, the cloud

Context. Lynds 1780 is a high-latitude cloud where, based on 2MASS, the maximum visual extinction is A max V = 4 mag at a resolution of 3'. In LDN1780, increased far-infrared (FIR) emissivity of dust grains has been observed, and the infrared emissio
