How do transmittance, absorbance, and molar absorptivity differ? Which one is proportional to concentration? - correct answers *transmittance* = (P/P0) *absorbance* = log(T) absorbance is proportional to concentration Why is it most accurate to measure absorbances in the range A = 0.3-2? - correct answers If absorbance is too high, too little light reaches the detector for accurate measurement If absorbance is too low, there is too little difference between sample and reference for a...

Raman spectral imaging The first step of Raman spectral imaging is to record a Raman map. There are roughly three hardware approaches in recording Raman maps – point mapping, line scanning and global imaging. Point mapping is the most often used method in the industry because Raman maps acquired achieve the highest spatial resolution and image quality. The laser illuminates a point on the sample to record a Raman spectrum, and the sample is moved along both X- and Y-axis....
