Bruker’s patented 90 degree ion mirror [1, 2] provides
unsurpassed efficiency for the transfer of ions from the
interface to the mass analyzer. This enables the new Bruker
810/820-MS to achieve a sensitivity of more than 1000
million c/s per mg/L of analyte, while maintaining oxide
ratios (CeO+/Ce+) below 3%. In addition, the Bruker 820-MS
is equipped with Bruker’s unique and patented interference
management system [3], the Collision Reaction Interface
(CRI). The CRI reduces common polyatomic interferences
on elements such as As, Se, Cr, V and Fe, thus achieving
lower detection limits in hot plasma. In this application
note, typical detection limits for some elements commonly
regarded as ‘difficult-to-analyze’ by conventional ICP-MS
are determined using the Bruker 820-MS in its normal
sensitivity mode.
