Helium Mode Icp Ms. An Agilent 7700x ICP-MS incorporating a newly designed ORS. Triple quadrupole ICP-MS instruments are an adaption of single quadrupole systems with an additional quadrupole being inserted prior to the collision cell. It atomizes the sample and creates atomic and small polyatomic ions which are then detected. High sensitivity is achieved for all elements.
We could not obtain a value of 2400 cps for Co 59 as suggested by the tech specialist. The collision cell is pressurized with helium gas which collides with the ions. Based polyatomic interferences takes place in the collision cell by KED using helium gas as the collision gas. Here in part 2 Im going to explore what can be achieved using reactive cell gases. Cell all analytes measured with a single cell gas. The 7700x offers the following capabilities.

Here in part 2 Im going to explore what can be achieved using reactive cell gases. Cell was applied to this very challenging application. Agilent 7700 Series ICP-MS has been developed to give the highest performance in helium He collision mode. You can find clear complete and useful information on HEHe on that flyer. Our unit by the way is Agilent 7700x with 770 series icp-ms masshunter workstation. Because the ionization energy of He 246 eV is higher than that of Ar 158 eV the use of He ICP as an ion source for MS has potential of enhancing the degree of ionization for every element in particular for non-metals.
