Agilent 7700 Series Inductively Coupled Mass Spectrometer | Agilent Technologies, Inc.

General Description
The Agilent 7700 Series Inductively Coupled Plasma Mass Spectrometer (ICP-MS) is a fast, multi-element, high sensitivity trace metals analysis technique found in key applications such as environmental, foods, clinical, chemical, pharmaceutical, nuclear, and academia. The new 7700 series ICP-MS provides the most robust plasma (lowest CeO/Ce ratio) of any commercial ICP-MS for superior ionization of sample. Agilent’s unique high matrix introduction (HMI) technology further improves matrix tolerance to allow routine measurement of % levels of matrix. The 7700x also includes Agilent’s innovative 3rd generation Octopole Reaction System (ORS3) cell for effective removal of interferences in complex and variable samples. The compact benchtop design makes the 7700 the world’s smallest commercial ICP-MS. With its high-temperature plasma, matrix tolerant interface and 9 orders dynamic range, the 7700x provides the ideal combination of robustness, sensitivity and analytical range yet retains the flexibility to handle advanced research applications.

Technical Description
All 7700 Series ICP-MS systems feature:

Sample Introduction - includes an efficient, low-flow concentric nebulizer, a temperature-controlled spray chamber and a high precision, 10-roller peristaltic pump.
Plasma RF Generator - high power-transfer efficiency and maintenance-free solid state digital drive 27 MHz RF generator with variable-frequency impedance matching.
Torch - Easy-mount, one-piece quartz torch with wide 2.5mm internal ID injector maintains the highly robust plasma needed to efficiently decompose the sample matrix.
Ion Lenses - Redesigned extraction and off-axis ion lenses provide high ion transmission for high sensitivity and low backgrounds, combined with uniform mass response across the mass range.
Octopole Reaction System –The ORS3 is longer and narrower than the 7500 Series ORS cell, and operates at higher frequency, higher cell gas pressure and higher kinetic energy discrimination (KED) bias voltage.
Quadrupole Mass Analyzer - The 7700 uses a true hyperbolic quadrupole, unique in ICP-MS, operating at high (3MHz) frequency.
