Automatic Distillation by Herzog
1
Clean all glassware and thermometer thoroughly prior to beginning analysis.
2
Swab condenser tube with a chamois cloth fastened to a long piece of wire.
3
Fill the measuring cylinder (receiving cylinder) with sample to 100% by volume mark ensuring that bottom of meniscus is exactly at
the mark.
4
If glassware is new or was cleaned in muffle furnace so that no burned material remains on bottom of flask, add one or two boiling
chips to flask to reduce bumping.
5
Pour sample from cylinder into flask ensuring side arm of flask is pointed upward.
6
Place the correct flask support board on the heater – use 38 mm hole board for Group 1 or 2 samples (gasoline) or 50 mm hole
board for heavier samples such as diesel or kerosene.
7
Insert sample thermometer into flask such that the top edge of the PT 100 (in the tip of thermometer) lines up exactly even with the
lower inside edge of the sidearm (see diagram below).
8
Place flask on support board and adjust heating plate by turning the small
hand wheel until the end of the silicone stopper on side arm fits snugly
into the condenser opening.
9
Ensure flask sits precisely in center of support board hole and is in a vertical
position (not leaning sideways).
10
Attach the metal drop plate in receiving cylinder so that tip of plate touches
inside of cylinder wall.

22
If all parameters are acceptable, click on the “Acknowledge” button on display screen on PC and a box will pop up where the amount
of residue is entered to 1 decimal place.
23
