Agilent 8900 Triple Quadrupole ICP-MS G3665AA

The Agilent 8900 Triple Quadrupole ICP‑MS (model G3665AA) is a tandem‑quadrupole inductively coupled plasma mass spectrometer (ICP‑MS/MS) designed for ultra‑trace multi‑element analysis. It uses MS/MS (ICP‑QQQ) capability and a collision/reaction cell to control reaction chemistry and remove spectral interferences, enabling reliable measurement of difficult elements and high‑purity/semiconductor process samples. Primary use cases include ultratrace impurity analysis, high‑matrix sample analysis, nanoparticle characterization, and applications that require separation of isobaric and polyatomic overlaps.

Key Features:

• ICP‑MS/MS (triple quadrupole) configuration for MS/MS operation
• Four‑channel cell gas control (multiple reaction/collision gases and modes)
• Ultra High Matrix Introduction (UHMI) tolerance up to 25% total dissolved solids (TDS)
• Helium collision mode plus reaction‑chemistry (mass‑shift) capabilities
• Semiconductor configuration sample introduction options (PFA MicroFlow nebulizer ~200 µL/min; quartz Scott double‑pass spray chamber with Peltier cooling; 2.5 mm injector; platinum‑tipped cones)

Advantages:

• Controlled MS/MS reaction chemistry provides effective removal of isobaric and polyatomic interferences for elements such as Si, P and S
• UHMI and robust plasma design allow reliable analysis of high‑matrix or challenging samples without extensive dilution
• High sensitivity and low background yield very low detection limits for ultratrace analytes
• Flexible cell gas and operation modes support method development for semiconductor, environmental, materials and nanoparticle applications
