The LDGDS is a user’s friendly gas dilution system that offers all the flexibility to generate manually or automatically the desired gas mixtures. The Windows user’s interface gives the ability to control and monitor the mixtures, flows, pressures and the concentrations. The system can store multiple gas cylinders mixture and it becomes easy to select the right cylinder to generate different blends. It reduces the cost of having specific standard for each blend needed. The dilution system is designed with a manual or automatic pressure controller installed on the zero gas line, on the span gas line and to regulate the outlet blended gas line pressure. This way, it improves the stability and the regularity of the flow controls. Each flow table uses a 10 points calibration curve to characterize the linearity of each flow controller.To ensure ultra high purity zero gas reference to generate ppb blends, an optional integrated heated gas purifier can be mounted on the zero gas flow path.
