Page 12: Software Description
1.3.1 Embedded gas chromatograph (GC) firmware The GC’s embedded firmware supervises operation of the Rosemount 700XA through its internal microprocessor-based controller. All direct hardware interface is via this control software. It consists of a multitasking program that controls separate tasks in system operation, as well as hardware self-testing, user application downloading, start-up, and communication.
Page 13 Reports and logs that can be produced, depending upon the GC application in use, include, but are not limited to, the following: • Configuration report • Parameter list • Analysis chromatogram • Chromatogram comparison • Alarm log (unacknowledged and active alarms) Rosemount 700XA...

Each thermistor is enclosed in a separate chamber of the detector block. One thermistor is designated the reference element, and the other thermistor is designated the measurement element. See Figure 1-2 for a schematic diagram of the TCD. Emerson.com/Rosemount...
Page 15 The temperature change unbalances the bridge and produces an electrical output proportional to the component concentration. The differential signal developed between the two thermistors is amplified by the preamplifier. Figure 1-3 illustrates the change in detector electrical output during elution of a component.

Page 16 Rosemount MON2020. 1.4.2 Flame ionization detector (FID) Another detector available for the Rosemount 700XA is the flame ionization detector (FID). The FID requires a polarization voltage, and its output is connected to the input with a high impedance amplifier that is called an electrometer. The burner uses a mixture of hydrogen and air to maintain the flame.
Page 17 (PMT) and processed by the signal processor. The response to phosphorus is linear and quadratic to sulfur. The Emerson µFPD solution consists of three key parts: burner, fiber cable, and PMT electronics. The hydrogen and air in the burner help to burn the sample containing sulfur components.

Page 267: Appendix C Micro Flame Photometric Detector (Μfpd)
Micro flame photometric detector (µFPD) The latest version of the Rosemount 700XA is now designed with an integral µFPD. In previous versions of the gas chromatograph (GC), side-car design was the only option for the FPD. The new design reduces the gas chromatograph's footprint and eliminates the side-car.
