What is a process gas chromatograph?

Process Gas Chromatographs (Process GC’s) are purpose-built gas monitors which provide specific data, both qualitative (species) and quantitative (amount), regarding the composition of a gas stream or sample found in an industrial or atmospheric application.

Who makes gas chromatographs?

Yokogawa
Yokogawa Analytical Manufacturer of gas chromatography (GC) instruments. Process gas chromatographs including gas chromatographs with built in 12-inch color touch screen display are available. Chromatographs are used in oil and gas, refining and petrochemical industrial applications.

How does a gas chromatograph mass spectrometer work?

The GC works on the principle that a mixture will separate into individual substances when heated. The heated gases are carried through a column with an inert gas (such as helium). As the separated substances emerge from the column opening, they flow into the MS.

How long does gas chromatography take?

Either gaseous or liquid samples, as small as several micro-liters, can be analyzed. And the whole process of GC/MS analysis takes about one hour or less, depending on the complexity of the compound to be analyzed. The two major components of GC/MS are the gas chromatograph and the mass spectrometer.

What is a natural gas chromatograph?

Process gas chromatography is used for separating and analyzing chemical compounds in the gas phase of industrial processes. Since the mid-twentieth century, the gas chromatograph has made a name for itself as a do-all analytical instrument with analysis capabilities ranging from percent level to ppm.

What is the first peak in gas chromatography?

50°C
At 50°C, the solvent effect occurs, allowing the good shape for the first peak. Since the solvent effect is necessary for splitless injections, the general rule is to use an initial oven temperature 10–30°C below the boiling point of the sample solvent.

How does Siemens process gas chromatograph system work?

While Siemens process gas chromatograph, system integration packages and analytical monitoring systems undergo a rigorous set of final production tests and documentation, some customers still elect to check the system with a Factory Acceptance Test (FAT) before shipment. Siemens offers a variety of options to meet your needs.

How is SSSI used in process gas chromatography?

With the SSSI, key operational information is automatically transferred from the sample system to the remote maintenance stations, and also supports the path of digitizing the maintenance of the SCS. With its improved detector geometry, the new TCD makes the measuring system not only safer but also even more precise.

How can Siemens help you with continuous gas analysis?

Siemens experts are available with a variety of training courses and to help you understand gas chromatography and continuous gas analysis and how to operate and maintain your Siemens analytical products. Siemens offers both introductory and advanced courses several times a year. How can we help you?

Which is the best process gas chromatograph to use?

The Maxum Modular Oven (MMO) process gas chromatograph is the ideal solution when simple reliable performance is needed. Using removable analytical modules, maintenance is greatly simplified for lower maintenance costs. The MMO simple design means it can be delivered in half the time as a traditional Maxum gas chromatograph.
