The G4800 and S Series generators are laboratory sized hydrogen generators designed for use with multiple GC and GC-MS instruments. These generators utilizes PEM technology to produce high purity hydrogen consistently on-site. They are  capable of handling all gas chromatography requirements for labs with 10 to 120 GC-MS instruments, or 50 to 240 FIDs.
