Why is the GC so commonly used in cooperation with a Mass Spectrometer? - ️️These two components, used together, allow a much finer degree of substance identification than either unit used separately. It is not possible to make an accurate identification of a particular molecule by gas chromatography or mass spectroscopy alone.Sometimes two different molecules can also have a similar pattern of ionized fragments in a mass spectrometer (mass spectrum). Combining the two processes reduces the ...

Experiment # 5 Bonding Type by Solubility, Distillation, and IR Spectroscopy Purpose: Different methods to identify inter and intramolecular bonding types. Procedure: A. Solubility 1) Place sample of KCl into a test tube filled with water. Take note of any layers separating the water with the added material. Mix the materials together in the test tube. Note if the mixture is homogenous or remains separated. 2) Repeat the process each for pentane, n-propyl chloride, ethyl alcohol, n-butyl...

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...
