Resolution. . . . . . . . . . . . . . . . . . . . These settings in the Tune program affect the
way the mass spectrometer resolves peaks.
Increasing the resolution narrows the peaks
in that mass range, while lowering the
resolution will broaden the peaks.
Retention Time . . . . . . . . . . . . . . . . The time from injection of a specific
compound onto the GC until the compound
appears at the exit (same as elution time).
Reverse Search . . . . . . . . . . . . . . . A function of the NIST search (tentative
unknown identification) library which allows
compounds which are specified in the user
Library to be identified as part of the search.
RH . . . . . . . . . . . . . . . . . . . . . . . . . . Relative humidity.
RIC . . . . . . . . . . . . . . . . . . . . . . . . . . (Reconstructed Ion Chromatogram) A
presentation of the chromatographic record
which extracts from the TIC and displays the
intensity of the ion or ions specified.
Round Trip Time. . . . . . . . . . . . . . . The amount of time required to complete a
scan of all the masses specified in a SIM
method. This includes the number of
masses, integration time, number of extra
measurements, lead in time, and peak width.
RL . . . . . . . . . . . . . . . . . . . . . . . . . . Right Limit.
RMA . . . . . . . . . . . . . . . . . . . . . . . . . Return material authorization document.
Returning material can not be sent back
without this document.
RMB . . . . . . . . . . . . . . . . . . . . . . . . . Right Mouse Button.
% RSD . . . . . . . . . . . . . . . . . . . . . . . Percent Relative Standard Deviation. This is
a measure of the linearity (using
mathematical regression analysis) of the
concentration levels in the calibration curve
for each compound.
Sample Loop. . . . . . . . . . . . . . . . . . The portion of the gas chromatograph
through which the inlet flow is directed and
from which the injection is made.
Sample Vial . . . . . . . . . . . . . . . . . . . In this situation, sample vial refers to a 40 mL
glass vial with a plastic cap and PTFE/silicon
septum.
