Joint Analytical Systems GmbH (JAS) products

The JAS GBS allows automated sampling of gases, stored in tedlar bags or gas sampling balloons, as well as gas cylinders, e.g. calibration gas cylinders. Sample transfer is carried out via a multi-position valve. Each gas sampling inlet is equipped with an in-line filter to avoid multi-position valve blocking. Connection to the GC can be made by means of 1/16” SS tube. The GBS is controlled via a special JAS Control Software.

Reproducible results with low Relative Standard Deviations (RSD; measured in percent) are two main aspects of modern gas analysis. Fundamental is the gas sample injection at reproducible and controllable volumes, pressures and temperatures. This is especially challenging in cases where one GC system is required to handle samples coming from different sample containers and where the sample characteristics may vary from injection to injection.
