LIFE CHARACTERISTICS
Ion detector service life depends greatly on output
current magnitude and ambient conditions. In particular,
the service life of ion detectors tends to drastically
shorten when used in LC-MS. The Hamamatsu H8285
ion detector was specially designed to eliminate this
problem of a short service life, making it ideal for LC-MS
applications. The H8285 has a conversion dynode that
efficiently converts input ions into electrons. These
electrons are then guided to strike the phosphor surface
where they are converted into light. This light is then
detected and amplified by a photomultiplier tube with a
unique vacuum envelope. These design features ensure
that the H8285 ion detector will have a long service life.

The R5150-60 and R5150-70 ion detectors deliver
greatly improved sensitivity especially for high mass
numbers when used with a mass spectrometer. This high
sensitivity was achieved by the electrode design that
allows applying a high voltage to a conversion dynode to
increase the input ion energy. Sensitivity was further
enhanced by using optimized ion and electron trajecto-
ries to achieve a peak intensity even when detecting only
small amounts of a sample. The R5150-60 and R5150-
70 are also designed to minimize detection of noise
components generated from the ion source, so the base
line noise level has now shrunk to an acceptable level.
