Specifications
flow automatically within the range of 0 to 2.0 liter/minute in 0.1 liter/minute
increments.
Nebulizer Argon Flow:
Computer-controlled, using a mass flow controller, and is
variable between 0.00 and 2.00 liter/minute in 0.01 liter/minute increments.
Shear Gas:
A compressed-air shear gas (18-25 liters/minute) is used to push the
plasma plume out of the optical path, minimizing the impact of self-absorption in
the cooler plasma plume.
Sample Introduction System
Torch:
Demountable design using one-piece quartz tubing for plasma and
auxiliary gas flow. The standard torch is supplied with a 2.0-mm alumina injector
for full corrosion resistance to all acids, including hydrofluoric and aqua regia. A
0.8-mm injector is available as an option for analysis of very volatile organic
solutions. As options, 3.0-mm, 1.6-mm and 1.2-mm quartz injectors are available.
Also available is a 2.0 mm sapphire injector (mainly used for analyses requiring
very clean low level determinations).
Spray Chamber:
Scott-type designed to minimize pulsations from the peristaltic
pump and constructed of Ryton for complete corrosion resistance to most acids,
including HF, and all organic solvents normally used in ICP analyses.
Nebulizer:
Cross-flow design with chemically resistant GemTips manufactured
from corrosion-resistant (sapphire tips in a PEEK body) material. The system can
routinely handle 50% (v/v) solutions of HCl, HNO

, 20% (v/v)
HF and 30% (v/v) NaOH. Up to 20% NaCl can be aspirated by the nebulizer for 1
hour without clogging. The system is fully compatible for use with other nebulizers
such as ultrasonics, concentrics (MEINHARD) and GemCone types.
Peristaltic Pump:
A four channel, variable speed, computer-controlled pump.
Speed is variable from 0.2 to 7 mL/minute in 0.1 mL/minute increments using 0.76
mm (0.030 inch) tubing.
Torch Mount:
In Quick-Change Torch Module both horizontal and vertical
viewing of the plasma are optimized by computer-controlled movement of the first
transfer mirror.
User Plasma Viewing:
The full plasma is viewed through a UV-blocking, low-
transmittance window located in the torch compartment door.
