Process and Online productlines
Process and Online productlines enhances the standard GC equipment from Agilent Technologies with unique engineered inlets, sampling systems, valve solutions, control units, etc.
Valve Solutions
For gas analytics and process chromatography has developed customized valve systems. The ValveBox, installed on a GC7890/6890 or 6850, provides sophisticated valve and column switching assemblies to manage analyses of highly complex gas mixtures, e.g. LPG or Natural Gas.
Due to special heated transfer lines a process GC can be easily integrated into any industrial plant, providing fully automatted time-saving online anlyses at site.
Turn Key Process Solutions
Customized, space-saving combination of sample preparation, GC system(s) and PC. Benefit from a mobile analytical unit by enhancing your flexibility in process applications.
Process and Analytic micro GC
The Micro GC is very well suited for:
- Refinery Gas Analysis
- Natural Gas Analysis
- Environmental Analysis
- Fuel Cell Analysis
- Process Monitorin
The analytical results from the lab are:
- Time delayed by distance
- Not always 24h garanteed
- not available or implementable in the PCS (process controlling system) data format
This integration is performed with modified standard GCs. The following instruments are available Agilent Technologies 7890 / 6890 or 6850 GCs. With all detectors e.g. FID, TCD, AED, NPD, SCD, HID.
Furthermore, offers customized configurations including heated transfer lines, heated valve boxes and special valves for gas- and liquid sample streams as well as multi-position valves for streamselection.
Integration of GCs into industrial production plants
- Installation of analytical systems into Analyzer Shelters
- Practical points for On-Line sampling
- Vacuum pumps for sample transport(gasses or liquids)
- The distance between sampling point and Analyzer Shelter can be bridged with heated or non heated transfer lines
Controlling and evaluation is performed by Agilent Technologies ChemStation SW:
- GC Parameters ( Oven program etc. )
- Valve controlling
- Calibration
- Evaluation
- Feed back analysis information into PCS (both analog or digital solution available)
For the date transfer uses:
- ChromGate for Analog ( 4 - 20 mA ) data transfer
- ProfiBus or LAN for digital data transfer
Integration of GC systems into industrial environments
Advantages of GC-based on-line solutions:
- Simple system set-up and implementation
- No new method development neccesary
- No additional personnel costs
- Calibration and control of data is performed by qualified laboratoty personnel
