GLOSSARY

Auto Zero: Automatic zeroing of the preamplifier. May be entered into the Controller to take place
at any time during the analysis when either the component is not eluting or the baseline is
steady.
Chromatogram: A permanent record of the detector output. A chromatograph is obtained from a
PC interfaced with the detector output through the GC Controller. A typical chromatogram
displays all component peaks, and gain changes. It may be viewed in color as it is processed
on a PC VGA display. Tick marks recorded on the chromatogram by the GC Controller
indicate where timed events take place.
Component: Any one of several different gases that may appear in a sample mixture. For example,
natural gas usually contains the following components: nitrogen, carbon dioxide, methane,
ethane, propane, isobutane, normal butane, isopentane, normal pentane, and hexanes plus.
Condulet: Fitting resembling a pipe or a box with a removable cover for access to electric conduits.
CTS: Clear to send (a serial port pin assignment).
DCD: Data carrier detect; see also, RLSD (a serial port pin assignment).
DSR: Data set ready (a serial port pin assignment).
DTR: Data terminal ready (a serial port pin assignment).
