The CHROMTECH EVOLUTION is built upon the most popular GC/MS-System, the AGILENT 5973/5975 series MSD. Keeping the original inert ion source, the true hyperbolic quadrupole and the highly sensitive HED detector provides the best possible basis for the next logical step in mass spectrometry: MS-MS. By adding a proprietary IonRail collision cell and another high precision quadrupole-serving as mass filter Q3 - the AGILENT MSD is easily upgraded to a triple quadrupole instrument, the CHROMTECH EVOLUTION. Imagine all the possibilities of MS/MS combined with the ruggedness and reliability of the AGILENT MSD 5973/75 series base instrument.
