Eco-friendly Carrier Gas Saver Function Reduced Operating Costs

Because helium is an expensive resource, its use as carrier gas During annual operation, when the auto start/auto stop
should be minimized. The carrier gas saver function allows you functions of the GC-2025 are used, a reduction in power
to reduce the carrier gas emitted from the system by reducing consumption of nearly 57% will be realized as compared to the
the split ratio in the analysis. In a split / splitless sample injection existing model. In addition, CO2 emissions will be reduced by
method, this function can save valuable carrier gas and thus approximately 378kg.
reduce operating costs.
*Annual operation is defined as 260 days. A power conversion factor of
0.378kg-CO2/kwh used.
