Gas composition

Isolab uses a custom setup to analyse the composition of all types of gas. The set-up is optimised for the analysis of all types of samples, with low or high concentrations, pressurised or not. A few highlights:
- Hydrocarbons (C1-C6+) + permanent gasses
- Helium and hydrogen
- High and low concentrations (ppm level)
- Pressurised, not pressurised, headspace
- Very small volumes (down to 1ml)

Stable isotopes of gas components

Gas is separated into its individual components, from which the stable isotopes are analysed. The most common analyses on gas samples are:
- Carbon or hydrogen isotopes of methane - pentane
- Carbon or oxygen isotopes of CO2
- Nitrogen isotopes of N2
- Hydrogen isotopes of H2
These analyses can be performed on low or high concentrations of the measured components. For low concentrations, cryogenic enrichment is used without additional costs.

Sample types

Isolabs equipment is optimised for natural gas samples and their derivatives, but most other types of gas samples can be analysed. Some examples:
- Natural gas, pressurised or not pressurised
- Mudgas
- Headspace gas
- Dissolved gas
- Single components or gas mixtures
- Samples with hydrogen and/or helium

Sample containers

Gas samples are best conserved in pressurised cylinders. Isolab prefers cylinders with a volume of 150-500ml, pressurised to 5-10 bars, with a ¼” Swagelok connection.
Other sample containers that can be used:
- Gas bags
- Isotubes
- Isojars
- Isoflasks
- Glass vials
- Various types of gas cylinders
- Etc.
