Process Gas Chromatographs

GC8000 process gas chromatographPrecise Process Gas Chromatography

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. Traditionally, process gas chromatographs have been used in the hydrocarbon industry, but have expanded to use in a wide range of industries from chemical process to power.

Yokogawa Technical Report

In recent years, shale gas extraction technology has made rapid progress, inducing a shale gas revolution mainly in the USA. Thus, the need for analysis of hydrocarbon gases, including natural gas, is expected to grow rapidly. Traditionally gas chromatography has been used for the analysis of hydrocarbon gases; it can accurately measure the concentration of each hydrocarbon component in a sample of natural gas.


Loek van Eijck, Yokogawa, The Netherlands, questions whether rapid analysis of gases and liquids can be better achieved through use of a gas chromatograph or near infrared analyser. Conventionally, the liquid and gas components such as those broken down by naphtha crackers have been measured by a process gas chromatograph (PGC), with the subsequent measurement values then being used for control purposes.




The GC8000 is a process analyzer that uses gas chromatography to measure the composition of multiple components in a stream. Engineered with reliable electronics and intelligently designed columns and valves, the GC8000 improves ease of maintenance while reducing operating costs. Its intuitive touchscreen HMI with system diagnostics reduces operation and maintenance headaches, maximizing measurement accuracy, reliability, and uptime. More Information


Yokogawa programs each oven to suit one or multiple process samples via its main components (sets of valves, columns, and detectors explicitly designed to the customer's application), and the combination of which is based on the chemical properties of all or some of the components in the specific gas mixture.


The GC8000 has an innovative predictive diagnostics; Virtual Tech, package built in to help keep the unit operating at peak performance. A number of Key Performance Indicators (KPI) are monitored during every analysis to verify the analyzer is operating within proper tolerances. The data monitored includes: Chromatogram Shape, Peak Data, Valve Data, Detector Data, Oven Performance Data


The GC8000 has a built-in 12-inch color touch screen display that dramatically simplifies maintenance. At the touch of the screen, the technician can access all of the analytical parameters and measurement results; displayed in easy-to-understand graphical color screens.


The Yokogawa GC8000 HMI provides simple overview screens show the analyzer’s operation at a glance to trend displays of Key Performance Indicators (KPI). Easily navigation to the information or task that needs to be accomplished simplifies routine GC maintenance as well as enables technicians to quickly begin using the analyzer with minimal training. In this 20 min HMI Introduction video we walk you through how to set-up a GC. During the training, you can see first-hand how quickly you could feel comfortable with the GC8000 interface.


To ensure peak performance, efficient GC maintenance is very important, especially now that many end users face a decline in supporting technical resources. In this webinar, we will show you how to optimize a GC maintenance plan.

You will learn:

  • How to select the right sample system for your GC
  • Installation considerations for optimal GC performance
  • Best practices for maintaining a GC
