Does EPOND supply 'micro-nebulizers' for low-uptake ICP applications ?
Yes, and in several materials and configurations ... cross-flow and concentric types,
with good performance right down to less than 5 microlitres/minute.
ESI's MicroFlow and PFA-ST nebulizers are industry standards
for low-uptake applications - physically robust and able to tolerate any solvents including HF.
EPOND's Zefyr has such a low level of stable, aspirated uptake that it
can inject sample directly into the base of an ICP injector.
What is the shelf life of an ICP-MS detector from EPOND ?
If kept in a dry, inert-gas environment with no exposure to strong light, vibration or
temperatures outside the range 10 to 25 deg.C., the shelf life will be at least 2 years.
What's this nebulizer "vacuum" that I've heard about ?
Most pneumatic, concentric nebulizers develop a pressure drop at their gas orifice,
effectively a 'vacuum' ... they can therefore pump, or aspirate, liquid samples. This can be
very useful, as contamination from peristaltic-pump tubing can be completely avoided if sample
is aspirated in this way.
This method of sample delivery is increasingly used with new autosamplers.
For more details of aspirated uptake - see the EPOND
No-Break nebulizers site. ,
Does EPOND have a full-line catalogue on paper ?
A 1-MegaByte PDF-file catalogue of ICP accessories
is available for download.
Email us for lists of components with prices, relevant to the ICP instrument types or applications that you have.
How can I clean a glass nebulizer without breaking it ?
Don't use an ultrasound cleaner or a wire, in case you were tempted : if simple
rinsing or reverse-pumping doesn't work, then use an EPOND
PEARL cleaning device -
it fits all types of concentric glass nebulizers ... yes, all types !
How should I measure the self-aspiration rate of an ICP nebulizer ?
The best way to do this is with a
'PLUTO'
or a 'SEDNA' ,
electronic devices that measure microlitres/minute
uptakes accurately in seconds - in the range 5 to 2000 microlitres per minute or more.
The patented measurement system of the PLUTO and the SEDNA is non-contact and has software
that permits re-configuring for your individual requirements.
Does EPOND supply MS accessories and chromatography supplies ?
No we don't, but we can recommend a company that
does this, and more besides - MS Wil GmbH in North
East Switzerland. They have specialized in mass spectrometry accessories
and consumables, as well as GC and LC consumables, for nearly a
quarter century.
