Torch

The torch has a standard alumina injector with a 2.0 mm inner diameter. Other
injectors available include alumina injectors in different sizes for optimum sample
flow rate, and quartz and sapphire injectors for different sample types.

Spray Chamber

Depending on the instrument configuration ordered, the instrument may include a
Scott-type spray chamber with a GemTip Cross-Flow nebulizer or a baffled
cyclonic spray chamber with a Meinhard K1 nebulizer. Other combinations are
also available. A Ryton, double-pass Scott-type spray chamber with the GemTip
Cross-Flow pneumatic nebulizer is one of the standard configurations. This rugged
combination provides the best results for a variety of elements and sample types.

Nebulizers

PerkinElmer offers these nebulizers for a wide variety of applications:
Description/Part No.
GemTip Cross-Flow
Nebulizer end cap
N0780546
GemCone
(Conespray)
Nebulizer
High Solids: N0690670
Low Flow: N0690671
Sample Introduction System
Uses/Advantages
Good general purpose nebulizer for the
analysis of strong mineral acids (including
HF) and samples with less than 5% dissolved
solids. Uses GemTips made of sapphire and
ruby in a Ryton end cap for maximum
chemical resistance.
High Solids GemCone is for samples with
high dissolved solids (up to 20%). Low Flow
GemCone permits lower nebulizer gas flow
rates, useful for spectral lines with high
excitation energies and for providing a more
robust plasma. GemCone nebulizers require
an end cap (Part No. N0680343) for use with
the Scott spray chambers.
