Gas Pipeline Permeation Analysis
High pressure pipelines are used for transporting oil and gas. It is important to test the permeation of the materials used to manufacture the pipelines for a number of reasons. Firstly it is essential to test what levels compounds from the oil or gas to be transported through the pipeline permeate through the material. This helps to ensure that potential product loss and that ground contamination is kept to a minimum. It is also possible to monitor the degredation of the pipe material overtime to help ensure life expectancy of the material.

Ellutia have developed a customised version of the 200 Series Gas Chromatograph (GC) fitted with ;
- A Catalytic Converter (CC)/ Flame Ionisation Detector (FID) and a Flame Photometric Detector (FPD)
- An automatic 6 position Gas Sampling Valve, installed in the GC Column Oven.
- An automatic 8 position Stream Selection Valve (only 4 positions currently used)
- 4 Mass Flow Controller units (MFC) for controlling of sample gas flow (air) to customers membrane cell.

The flow of "sample air" to each cell is controlled by a mass flow controller and passes over the membrane to take up any of the sample gas being tested. Each cell under test is continuously purged with air and flows to the Stream Selection Valve and hence to the Gas Sampling Valve and flushes the sample loop. At the start of the analysis, the sample in the loop is injected on to the GC and the sample gas analysed. Sulfinert tubing and/or Hastelloy C material is used wherever the sample is in contact to minimise sample adsorption

About Us
Ellutia design and produce a range of innovative gas chromatography instruments. Ellutia systems are designed to be smaller, faster, give greater sensitivity and be more energy efficient. The main focus is to supply complete solutions to analytical problems. By collaborating closely with customers Ellutia are able to produce, install and support customised systems to fit their exact requirements. This flexibility and customer focus sets Ellutia apart from the competition.

History
Cambridge Scientific Instruments, from the UK and its sister companies; Advanced Chromatography Systems, from the USA and Unicam Chromatography, joined together to create the global chromatography solutions brand Ellutia. All three companies have been working closely together designing, producing and selling the same innovative range of gas chromatography instruments for over five years, but have always been perceived as separate entities. By coming together as a single unified brand Ellutia will be able to deliver even more consistent, higher quality services and products around the world.
