Sample degradation in autosampler

[kerri]

Can you continuously purge the autosampler compartment with Nitrogen and run your samples?

"Revived zombie" Well

My guess is that brushless motors should not produce sparks, but you can get ozone even without sparks.

From Wikkedpedia "Ozone may be formed from O2 by electrical discharges and by action of high energy electromagnetic radiation. Certain electrical equipment generate significant levels of ozone. This is especially true of devices using high voltages, such as ionic air purifiers, laser printers, photocopiers, tasers and arc welders. Electric motors using brushes can generate ozone from repeated sparking inside the unit. Large motors that use brushes, such as those used by elevators or hydraulic pumps, will generate more ozone than smaller motors." http://en.wikipedia.org/wiki/Ozone

IMHO not in this case
"Gay-Lussac law " http://en.wikipedia.org/wiki/Gay-Lussac's_law
Law of the Mendeleev-Clapeyron
Have you heard? No matematics formula,principles of law

If you use electric fan, you are constantly connecting a sample heat and air oxygen.
If you are sucking air vacuum, you are continuously evacuate oxigen from the system . And solvent evaporation => minimised energy (temperature in flack). Vapor solvent => a "gas cushion" up the solvent.


PS
Dear, remember childhood. And pick the at least one fan.
Only the "chYnese" hair dryers have collector engines. Room fans have induction motors.
Induction motors do not spark and the ozone does not form.

Where does Mattias say that he used a "room fan" ? He used an "electrical fan" .
