The Agilent 7700x/7800 ICP-MS combines the simplicity of a single collision cell mode (helium mode) for polyatomic interference removal with the superior matrix tolerance of its unique High Matrix Introduction (HMI) system. Octopole Reaction System (ORS) cell technology provides higher sensitivity and more effective interference removal than ever before in complex, high matrix samples, eliminating the need for reactive cell gases in routine analysis. Helium mode on the ORS is so effective that interference correction equations can also be eliminated. Agilent 8900 三重四極桿 ICP-MS
