Gas Chromatography-Mass Spectroscopy
cires1.colorado.eduGas Chromatography-Mass Spectroscopy Introduction Gas chromatography-mass spectroscopy (GC-MS) is one of the so-called hyphenated analytical techniques. As the name implies, it is actually two techniques that are combined to form a single method of analyzing mixtures of chemicals. Gas chromatography separates the components of a mixture and

Infrared Spectroscopy
mmrc.caltech.eduIntroduction Infrared (IR) spectroscopy is one of the most common spectroscopic techniques used by organic and inorganic chemists. Simply, it is the absorption measurement of different IR frequencies by a sample positioned in the path of an IR beam. The main goal of IR spectroscopic analysis is to determine the chemical functional groups in the ...
FTIR Spectroscopy: Attenuated Total Reflectance (ATR)
resources.perkinelmer.comIntroduction Mid-Infrared (IR) spectroscopy is an extremely reliable and well recognized fingerprinting method. Many substances can be characterized, identified and also quantified. One of the strengths of IR spec-troscopy is its ability as an ana-lytical technique to obtain spectra from a very wide range of solids, liquids and gases. However, in

web.mnstate.eduH NMR Spectroscopy and Interpretation: More Detailed than the “Summary” 89 Introduction to 1H-NMR Spectroscopy Hydrogen NMR spectroscopy is considerably more complex than 13C-NMR. The interpretation is more difficult. However, the extra complexity provides extra information that is unavailable from carbon NMR. In interpreting carbon NMR, we

Signal, Noise, and Detection Limits in Mass Spectrometry
www.agilent.comintroduction, separation, and detections processes in the instrument. The LOQ is the limit at which we can reasonably tell the difference between two different values of the amount of analyte. The LOQ can be drastically different between labs so another detection limit referred to as the Practical Quantitation Limit (PQL) is commonly used.
