Emerson 700 XA - Manual

1 Introduction This section describes the contents and purpose of the 700XA Gas Chromatograph System Reference Manual , a description of the Model 700XA system, an explanation of the theory of operation, and a glossary of chromatograph terminology. Use this section to get acquainted with the basic e...

The GC-to-PC interface provides the user with the greatest capability, ease-of-use, andflexibility. MON2020 can be used to edit applications, monitor operations, calibratestreams, and display analysis chromatograms and reports, which can then be stored asfiles on the PC’s hard drive or printed from ...

In most cases it is essential to use MON2020 to configure and troubleshoot the GC. The PCmay be remotely connected via ethernet, telephone, radio or satellite communications.Once installed and configured, the GC can operate independently for long periods of time. Gas chromatography process model Fig...

After the equipment/software has been installed and the operation stabilized, automaticoperation can be initiated via an ethernet network. 1.5 Theory of operation The following sections discuss the theory of operation for the GC, the engineeringprinciples and the concepts used. Note See Section 1.7 ...

In the quiescent condition, prior to injecting a sample, both legs of the bridge are exposedto pure carrier gas. In this condition, the bridge is balanced and the bridge output iselectrically nulled. The analysis begins when the sample valve injects a fixed volume of sample into thecolumn. The conti...

1.5.2 Flame ionization detector The other detector available for the 700XA is the flame ionization detector (FID). The FIDrequires a polarization voltage and its output is connected to the input to a highimpedance amplifier that is called an electrometer. The burner uses a mixture of hydrogenand air...

1.5.5 Data acquisition Every second, exactly 50 equally spaced data samples are taken (i.e., one data sampleevery 20 milliseconds) for analysis by the controller assembly. As a part of the data acquisition process, groups of incoming data samples are averagedtogether before the result is stored for ...

Onset is defined where the detector output exceeds the baseline constant, but peaktermination is defined where the detector output is less than the same constant. Sequences of fused peaks are also automatically handled. This is done by testing eachtermination point to see if the region immediately f...
