Agilent Single Quad 5975 GCMS Source Overview Video
Introduction
This video will present an overview of the source including function structure and common problems.
Source Operation
The function of the source is to create ions by means of E I or C I and transmit them into the quad. In E I, neutral compounds first enter the source from the GC transfer Line. Once the compounds are in the source they collide with 70 electron volt electrons from the filament forming ions. The repeller pushes the electron through the drawout plate. The beam of ions are focused by the ion focus and entrance lenses before they enter the quad. The magnet is helpful in optimizing the collision of the electrons with the compounds. Programing of the entrance lens voltage with the gain and offset help to facilitate the movement of the ions from the source into the quad. The entrance lens voltage is also critical in favoring biasing t More....
