HAPSITE ER Operating Manual

Recalculate . . . . . . . . . . . . . . . . . . . An option in the Calibration section of the

Run Method screen which allows the user to
compare an analysis to the calibration curve
without changing peak integrations. This
should be used when the user would like to
re-calibrate using the existing parameters.
The alternate choice is Search, which does
peak integration automatically based on
selected calibration curves.

Remote Power . . . . . . . . . . . . . . . . Power supplied to the HAPSITE and HSS

either from the Service Module (for the
HAPSITE) or external AC - 24 V(dc)
converter.

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.
