Turn valve towards back. b. Place bottle in lowest position possible. c. Insert stopper into open end of furnace tube. d. Raise bottle and place in upper rack. e. Observe pink confining solution liquid in calibrated column. Weigh samples into ceramic boats: 2 3 Ensure valve is turned towards back (closed). 4 Using tongs, place boat in end of furnace tube. 5 Turn on main valve for oxygen (gauge should read approximately 20 psi). 6 Use rod to slide boat into center region of tube. 7 Stopper open end of furnace tube.

Percent Carbon on Platformer Catalyst by Volumetric Are Revision Unit Operating Procedure # Certified by Date a # Procedure Continued 3 Lab 09. 201 1 OPS-LB-FL-008 Page 2 of 2 Percent Carbon on Platformer Catalyst by Volumetric Procedure (continued) 8 Open needle valve for oxygen (turning slowly) to purge sample. 9 Observe confining solution in column – when it reaches black line in reservoir, immediately close needle valve for oxygen. 10 Place bottle on lower rack. 11 Remove stopper from furnace tube. 12 Ensure that level of confining solution drops to 0. 00, if not then adjust by turning wheel located inside bottom rack. 13 Turn valve to left, raise bottle and place on upper rack. 14 Ensure glass float locks in confining solution (pink) reservoir, then turn valve towards back. 15 Wait 15 minutes. NOTE: Boat may be removed at this point with hooked rod. Pull boat carefully until reaches end of tube. 16 Lower bottle and simultaneously turn valve back to left position. 17 Continue lowering bottle until glass float in KOH reservoir locks then return valve to rear (closed) position. 18 Place bottle on lower rack and wait for liquid in column to stop rising. 19 Raise bottle slowly until liquid level in column is even with liquid level in bottle. 20 Record reading from calibrated column to 2 decimal places. 21 Turn valve to left (open) position to vent gas. 22 Ensure glass float locks in confining solution reservoir. 23 Remove boat from end of furnace tube with tongs and place on ceramic block in tray. 24 Shut off oxygen valve.
