System Description

RF Control Electronics
The RF generator uses solid-state circuits. The solid state RF generator is designed
to significantly increase reliability and reduce the need for recalibration.
The RF generator also monitors plasma conditions. If the plasma is unstable, the
system automatically shuts it off.
To ensure operator safety and to protect the instrument from damage, the system
includes extensive use of RF shielding and safety interlocks. Proper RF shielding
and filtering are provided so that the system complies with regulations regarding
radio frequency radiation.
Sample Introduction System
Sample and Torch Compartments
The sample compartment has a front door to provide easy access to the torch
compartment with the sample introduction model inserting into the torch
compartment through the bottom of the compartment. The sample introduction
system is always visible and accessible even during operation. The spray chamber,
nebulizer, injector and torch can all be accessed underneath the torch compartment
without opening the door. The torch compartment door has a window so that the
operator can safely view the plasma and safety interlocks that shut down the plasma
if the door is opened during operation. The torch compartment has extensive
shielding to prevent exposure to radio frequency radiation.
Quick-Change Adjustable Torch Module
The Quick-Change Adjustable Torch Module consists of the quartz torch, injector,
spray chamber, and nebulizer/end cap – all in one assembly. This module can be
quickly removed from the sample compartment. This adjustable mount allows the
torch an adjustment of up to 5 mm.
Torch
The torch has a standard alumina injector with a 2.0 mm inner diameter and a
sapphire injector in 2.0 mm diameter. Other injectors available include alumina
injectors in different sizes for optimum sample loading of the plasma and quartz
injectors for different sample types.
