Peltier Cooled Cyclonic Spray Chamber for
Agilent ICP-MS
The IsoMist Programmable Temperature Spray Chamber is now
well-established as the first choice when temperature flexibility
or temperature stability are required. However, for many ICP-MS
applications, a fixed temperature of around 2°C is used and no
flexibility is needed. For these applications, Glass Expansion has
released Peltier Cooled Cyclonic Spray Chambers for the Agilent
7700 and 7500 ICP-MS models. This accessory is based on the
spray chamber and Peltier system of the Isomist but is coupled to
the electronics and water cooling systems of the ICP-MS. Agilent
7700 and 7500 users can therefore get the benefit of a cyclonic
spray chamber at an economical price. Compared to the Scott
style spray chamber, the cyclonic spray chamber provides faster
washout and increased sample throughput.

D-Torch for Agilent ICP-MS
The D-Torch is a new demountable torch design that provides the
benefits of a fully demountable torch at a significantly lower cost.
We have previously released the D-Torch for several ICP-OES and
ICP-MS models. D-Torches are now available for the Agilent 7700
and 7500 ICP-MS models.
Part No. Description
30-808-3305 D-Torch for Agilent 7700
30-808-3015 D-Torch for Agilent 7500
The D-Torch is a cost-effective alternative to the standard fixed
torch or semi-demountable torch. It will save money for any
laboratory with a moderate workload. In most cases, when the
torch wears, you will only need to replace the outer tube instead of
replacing the entire torch. You will realize a saving after replacing the
outer tube three or four times. In addition, interchangeable injectors
are available to suit samples with organics, high solids or HF.

ConeGuard Thread Protector
When cleaning cones which have a screw thread, it is important
that the thread is not contacted by any corrosive solution. If the
thread gets corroded, the cone may not seal correctly or it may
bond to the base and be difficult to remove. And with Pt cones,
the thread is likely to wear out before the Pt insert.
Comments from the PLASMACHEM discussion group include:
“We noticed that the threads of the Copper based, Pt skimmer
cones would wear out long before the Pt insert.”
“We tend to clean the cones in dilute acid and judge they are
clean when they have a salmon pink “new penny” appearance. It
is in this condition that the copper cone is likely to cold weld to the
copper threaded insert in the interface assembly, and to the flat
thermal transfer area outside the thread.”
