Installation
Agilent 5800 and 5900 ICP-OES User's Guide 37
The MSIS consists of a nebulizer and modified glass cyclonic spray chamber that
has two vertical conical tubes in the center of the chamber. This allows for
reductant and sample to mix quickly and thoroughly in the chamber using thin film
hydride technology to form the hydrides.
The MSIS can be operated in three modes: hydride only, simultaneous hydride and
conventional nebulization or conventional nebulization only.
Argon Humidifier
The Argon Humidifier is commonly used when running aqueous samples with high
dissolved solids or high dissolved salt content. When using the accessory, the
nebulizer gas flow is passed through the humidifier to increase the water vapor in
the gas. This has been found to be beneficial by reducing the build-up of salt and
other dissolved solids in the nebulizer tip in the sample introduction system. By
reducing blockages, the Argon Humidifier helps to ensure uninterrupted,
maintenance-free operation.
IsoMist Programmable Temperature Spray Chamber
IsoMist utilizes the Peltier effect to provide electrical cooling or heating to the
spray chamber.
The ‘Set Temperature’ is monitored and controlled via the ICP Expert software. The
IsoMist performance can be monitored and controlled from a lab PC via USB or
Bluetooth wireless technology.
