เทคนิคการวัดไฮโดรคาร์บอน Analysis of permanent gases and light hydrocarbons with Plasma

The PlamaDetek is ideal to measure permanent gases and light hydrocarbons in different matrices. Only one detector system is needed to accomplish this task. Such measurement is required in many different applications field: industrial, petrochemical, energy, environmental, etc. The sensitivity, the stability, the ease of start-up and installation make this system very attractive for any users.
 
 
PLASMADETEK CONFIGURATION
 
The PlasmaDetek is configured with two outputs signal to be able to detect all components. Both argon or helium carrier gas can be used. Output 1 : H2, C1 to C4 Output 2 : O2, N2, CO, CO2 No need of fuel, air, dopping gas, methanizer or other
devices with the system. This is a stand-alone detector system that requires only carrier gas to make the measurement of each compound.
 
 
CHROMATOGRAPHY CONFIGURATION

 
To make the measurement of all components described above, figure 2 describes an easy configuration. Only one 10 ports injection valve and one selection valve are used. One RT Molecular Sieve 5A 30m x 0.53mm(column 2) separates H2, O2, N2, CH4, CO before being measured by the detector. The other column, a RT Alumina Bond 30m x 0.53mm x 10mm(column 1), does the same for the CO2 and C1 to C4.
• 1 x 10 ports injection valve
• 1 x 6 ports valve for channel selection
• 1 x RT Alumina Bond 30m x 0.53mm x 10mm (column 1)
• 1 x RT Molecular Sieve 5A 30m x 0.53mm (column 2)
• Argon or helium carrier
• Carrier Flow : 4 cc/min
• Make-up : 60 cc/min
• Detector : PlasmaDetek two outputs

CONCLUSION
With the PlasmaDetek, we can measure permanent gases and C1-C4 with only one detector. This is a very cost effective solution in terms of gas supply, plumbing configuration and time consuming. The performance is indisputable. Application in ppb is now easy to make with such configuration. Selectivity on some impurities can also be configured in the PlasmaDetek to make Chromatography easier when working on different background or focus on some impurities. Heavier hydrocarbons can also be measured. Please contact LDetek for more information.
