In this method, peak splitting reflects the number of adjacent atoms.
This method can generate a fragmentation pattern that is related to molecular structure.
Instrumentation of this type has a relatively low - end cost. A basic instrument is approximately $3,000, and a research - grade instrument is approximately $10,000.
his method gives information based on electronic transitions in molecules.
This method uses electromagnetic radiation from 200 - 900 nm to make measurements.
This method reflects how "shielded" atoms in a molecule are.
This method gives information about how atoms are connected to one another in a molecule.
This analysis type includes many methods, both instrumental and non-instrumental.
Neutral analytes must be ionized prior to analysis using this method.
This method is often used to determine molar mass.
This method uses electromagnetic radiation of 8,000 - 1,000,000 nm to make measurements.
Spectra from this method contain a “fingerprint region” that can be used to help identify a molecule.
This method uses electromagnetic radiation in the radiofrequency range.
The cost of this instrumentation varies significantly based on the type of detector that is combined with the instrument.
The spectra from this method contain very few peaks, often only one. Peaks are broad because of vibrational transitions within molecules.
This method must be coupled with another instrument or met hod.
The spectra from this method contain narrow peaks that give information about the types of bonds and functional groups present in a molecule.
This method gives information based on bond vibrational frequencies.
This instrument type distinguishes analytes based on their mass-to-charge ratios.
Instrumentation of this type is expensive ($250,000 plus $10,000 to $20,000 per year for upkeep and maintenance).
This method isolates analytes from complex mixtures.
This method can distinguish atomic isotopes.
The cost of this instrumentation depends on whether it is purchased as a stand - alone instrument, or as an integral component of a different instrument.
Instruments of this type can be configured with many different types of detectors.
