Sorry about the maths equation. The reason I gave it is to explain
why a small increase in column diameter gives such a large change in
performance or output, which is the "bottom line answer" to your
question. YOU NEED A BIGGER DIAMETER COLUMN to achieve bigger
output. (not shouting, just emphasising) :-)

All is relative. To increase output, you need to put more vapor up
the column. This requires more applied heat. More heat requires an
increase in column capacity, otherwise the vapor speed will increase
also, and reduce your purity.

The math on column capacity is easy to follow if you remember back
to school when they taught about circles. There are formulae for
circumference, area, cylinder volume (that's what we want).

To explain: Pi is always 3.1416 (near enough). R is radius of
column (half the diameter). ^2 is the previous number (radius)
multiplied by itself. Ht is the height of the column.
So for your column (cylinder) it's:
Pi x R^2 x Ht
3.1416 x 0.75" x 0.75" x 26" which gives 46 cubic inches.

If you increase the column to 2", then:
3.1416 x 1.0" x 1.0" x 26" which gives 81 cubic inches, nearly
double the volume or capacity.

This will enable you to increase the heat input without increasing
the vapor speed. Then you'll get your increased product output and
no loss of quality. But remember, all is relative. If you increase
the heat, you need to remove that increased heat at the condenser,
IOW up the coolant flowrate to match.

Slainte!
