Main functions

1.The new Hydro ion source can easily use hydrogen as the carrier gas, improving the chromatographic analysis performance and helping to avoid operational interruptions caused by the shortage of helium.

2.Data acquisition modes (such as data-dependent tMRM, and the simultaneous dMRM and scanning modes) enable targeted screening and reliable quantification of hundreds of analytes in a single run.

3.The MassHunter Optimizer software can easily transfer the GC/MSD method to the GC/TQ, and the retention time locking software can reproducibly transfer the method between gas chromatography systems.
