Procedure
 
 
 
1.   Determine the blank as follows:
a.   Enter the "blank" ID code with a 1.0000 g weight in the weight stack.
b.   Press the loader control switch, the sample loader will open.
c.   Place one 502-344 UHP Nickel basket into the loading head using clean tweezers.
（Place a 501-059 Tin capsule into the Nickel basket before placing it in the loading head.）
d.   Press the loader control switch, the sample loader will close and seal and the furnace electrode will open.
e.   Remove crucible from electrode tip and discard.  Clean furnace area using the appropriate brushes.  Vacuum away loose dust.
f.    Place ~0.05 g 501-073 into the bottom of a 782-720 crucible.  ~0.05 g is approximay a ¼ full
503-032 glass accelerator scoop.
g.   Place the crucible on the lower electrode.
h.   Press the loader control switch, the furnace electrode will close and the analysis sequence will start automatically.
i.    Repeat steps 1a through 1h at least four more times.
j.    Enter blank following routine outlined in operator's instruction manual.
2.   Calibrate the instrument as follows:
a.   Weigh the calibration sample. （Weigh the calibration sample into the tin capsule.）
b.   Enter the calibration sample ID code and sample weight in the weight stack.
c.   Place the calibration sample （capsule） into a nickel basket.
d.   Press the loader control switch, the sample loader will open.
e.   Carefully place the calibration sample/nickel basket （capsule） into the loading head using clean tweezers.  Make sure that the calibration sample （capsule） stays in the basket and the basket
stays upright.
f.    Press the loader control switch, the sample loader will close and seal and the furnace electrode will open.

g.   Remove crucible from electrode tip and discard.  Clean furnace area using the appropriate brushes.  Vacuum away loose dust.
h.   Place ~0.05 g graphite into the bottom of a crucible.
i.    Place the crucible on the lower electrode.
j.    Press the loader control switch, the furnace electrode will close and the analysis sequence will start automatically.
k.   Repeat steps 2a through 2j a minimum of three times.
l.    Complete a calibration by following the auto calibration procedure as outlined in the operator's instruction manual.
m.  Verify the calibration by analyzing the calibration sample again.  It should fall within the expected tolerances.  If not, repeat steps 2a through 2l again.
3.   Analyze the samples as follows:
a.   Weigh ~0.1 g sample. （Weigh the sample into the tin capsule.）
b.   Enter the sample ID code and sample weight in the weight stack.
c.   Place the sample （capsule） into a nickel basket.
d.   Press the loader control switch, the sample loader will open.
e.   Carefully place the sample/nickel basket （capsule） into the loading head using clean tweezers.
Make sure that the sample （capsule） stays in the basket and the basket stays upright.
f.    Press the loader control switch, the sample loader will close and seal and the furnace electrode will open.
g.   Remove crucible from electrode tip and discard.  Clean furnace area using the appropriate brushes.  Vacuum away loose dust.
h.   Place ~0.05 g graphite into the bottom of a crucible.
i.    Place the crucible on the lower electrode.
j.    Press the loader control switch, the furnace electrode will close and the analysis sequence will start automatically.
 
Theory of Operation
The TC500 is a microprocessor-based, software-controlled instrument that measures both nitrogen and oxygen in a wide variety of metals, refractories, and inorganic materials. The inert gas fusion principle is employed. A weighed sample, placed in a high-purity graphite crucible, is fused under a flowing helium gas stream at temperatures sufficient to release oxygen, nitrogen, and hydrogen. The oxygen in the
sample, combines with the carbon from the crucible to form carbon monoxide. The nitrogen present in
the sample releases as molecular nitrogen, and any hydrogen present is released as hydrogen gas. The helium carries the sample gases through heated rare earth copper oxide which converts carbon
monoxide to carbon dioxide （CO2） and hydrogen to water （H2O）. The nitrogen passes through
unchanged. The gases are then passed through a CO2  infrared （IR） cell where the oxygen is measured as
CO2. CO2  and H2O are then removed by a Lecosorb/Anhydrone trap, while the nitrogen passes through
to a thermal conductivity （TC） cell for determination.
