parameters into memory. This icon will appear automatically when the user

Preparing a
fusion program
To build your first fusion program, you must first select a preset program template
that will be used as a starting point to design your own program. In most cases,
the Oxide program is a good all-around program. Copy it under your desired
name, as described above.
Once this "editable" program exists, you can adjust parameters to suit your
sample.
Heating steps
Heating steps all have the same structure. Hence, if you need only two
temperature plateaus, you could use Heating 1 and Heating 2, or Heating 1 and
Heating 3, and so on, without affecting anything. For standardization purposes,
Katanax tends to use the last heating steps, and leave the first ones empty when
not needed.
Temperature
Note that he K2 Prime firmware prevents the user to create a decreasing
temperature. The instrument will prevent a heating step from having a
temperature that is lower than an earlier step. Also, the instrument will
automatically increase temperatures of subsequent steps to match the step being
edited.
Examples:
User is advised that too high temperatures will affect the life expectancy of the
heating elements, but can also lead to analytical problems, due to evaporation of
the flux.
Suppose that we have a program with Heating 2 at 500°C and Heating 3 at
700°C. You will not be allowed to decrease Heating 3 below the temperature
of Heating 2, i.e. 500°C.
Now suppose that the program has Heating 1 at 900°C and Heating 2 also at
900°C. If you increase temperature of Heating 1, the temperature of
Heating 2 will be automatically increased by the same amount.
Katanax does not recommend exceeding 1050°C when using lithium borates.
Katanax does not recommend exceeding 1000°C when using sodium borates.
Heating above those temperatures could cause flux evaporation that could bias
the subsequent analysis. Please contact Katanax if you feel that your sample
type needs higher temperatures.
Furnace temperature can be adjusted by
pressing on the plus and minus buttons
besides the crucible temperature icon.
