Agilent 7500 Series ICP-MS General Features Technical Note
Agilent Technologies has produced the 7500a, 7500i, and 7500s models of the 7500 series Inductively Coupled Plasma Mass Spectrometer (ICP-MS). These instruments are designed around a single powerful and robust analytical platform, sharing basic strengths in design and performance optimized for different analytical needs.
The document details key features such as the low flow nebulizer and wide diameter injector torch for high tolerance to dissolved solids, the Omega II off-axis lens system for high ion transmission, and a precision ground profiled molybdenum quadrupole. It also highlights the new simultaneous pulse counting and analog detector, which provides a linear dynamic range of up to nine orders of magnitude.
