Name detector: Sensitive detection of organic compounds over a wide linear dynamic range:
FID
Name detector: Selectivity and sensitivity for trace-level detection and analysis of compounds with electronegative functional groups:
ECD
The basic components in a mass spectrometer that are under a vacuum are:
Ion source, mass analyzer, detector
The factors that can be modified to control or modify resolution are:
Selectivity, Capacity and Efficiency
The migration rate of an analyte through a column
Retention Factor
In a triple quad instrument, the second quadrupole is where:
Fragmentation takes place
In electrospray ionization, the point at which the droplets break apart and a charge is imparted to the molecules within:
Rayleigh Instability Limit
Ionization Method: Uses a fine spray of LC effluent that is vaporized in a high-temperature tube:
Atmospheric Pressure Chemical Ionization
Ionization Method: Uses photons as the energy source for the ionization process:
Atmospheric Pressure Photo Ionization
Name detector: uses an electrically heated thermionic bead.
NPD
Breaking of a covalent bond in such a way that each fragment gets one of the shared electrons?
Homolytic Cleavage
