The SLS-2020 GC system sample line selector can connect up to 12 gas lines used for analysis. Carryover effects can be minimized by using a purge gas.
1. Six gases can be connected.
One standard gas, one purge gas and up to 4 different actual sample gases can be connected. (When using two SLS-2020s, twelve gases can be connected.)
2. Purge gas minimizes carry over.
When connected, the purge gas purges all the lines, thereby minimizing carry over. Any position can be selected for the purge gas line.

Standard gas only goes through the red line to sample loop, since there are several resistance pipes.

No contaminant peaks will be observed after purging the line.
3. Shimadzu workstation software can directly control the SLS-2020.

Greenhouse Gas Analysis
The greenhouse gas analyzer is a gas chromatography system that can simultaneously measure CH4, CO2, and N2O gases in a single sample injection, an analysis that was difficult to achieve with previous systems. Equipped with a robust high-throughput syringe injection system for processing up to 108 sample vials, this analyzer is designed to support research related to reducing greenhouse gas levels.
