WebAn extractive stack sampling method, using FTIR, has been developed for measuring HAPS. As one of the initial tasks in the project development, reference spectra were developed for as many of the HAPS as possible. Attached is a table which contains the quantitative reference spectral library as of June 1993 The table includes several columns of ... WebAn ATR accessory operates by measuring the changes that occur in an internally reflected IR beam when the beam comes into contact with a sample. An IR beam is directed onto an optically dense crystal with a high refractive index at a certain angle. This internal reflectance creates an evanescent wave that extends beyond the surface of the ...
