Town Gas Analysis
Periodical monitoring of calorific values is necessary to ensure a stable supply of town gas. Since Shimadzu’s system GC is robust and designed for automated analysis, it is widely used for 24 hour/day online analysis in this field.
Dedicated software is able to calculate calorific values and indexes automatically.
Using the sample line selctor SLS-2020, a single system GC can analyse multiple samples without switching the sample line. This saves both running and initial costs.
