In addition, both systems are equipped with Active Ion Management (AIM+) technology that includes redesigned ion source housing, segmented quadrupoles
, new RF electronics and an enhanced dual-mode electron multiplier detector for ultimate ion management from ion inception to detection.
mass spectrometry is the linking together of two quadrupoles
In "scan" mode, the voltages applied to the quadrupoles
are changed so that the instrument sequentially lets through ions across the entire mass range, typically over a period less than half a second.
But the systems were higher priced than quadrupoles
and accelerated the market's division into routine ICP-MS and high resolution ICP-MS segments.
yokes were available, but were too large for the experimental cave.
have developed a combination of a quadrupole
mass spectrometer (mass ranges up to 1000 amu) and an energy analyzer which, together with an appropriate sampling system, offers a sophisticated instrument for gaining maximum energy and mass information from plasma or ion beam processes.
Time-consuming cleaning of quadrupoles
is not required, and Agilent GC/MS systems hold highly stable tunes and methods for long intervals.
For this magnetic quadrupoles
are required for purposes of beam focusing.
are available in mass range options up to 16,000 amu with ppb detection capability and resolution characteristics that include a single detector capable of measuring neutrals, positive ions and negative ions.
These triple quadrupoles
are therefore capable of higher tolerance levels without significant loss of ion transmission.
are being considered for this application since they can monitor several chemical species simultaneously with a fast response time.
The rugged nature of Agilent's source design keeps the internal ion optics clean so that maintenance of the quadrupoles
and other internal lenses is rarely required.
