Confirm with scientists, what temperature and how long samples should be run for. Below is a quick reference guide:
Material | Ignition Time at °C |
Basalts | 4 or 5 hr at 1025°C |
Si-rich sediments | 4 or 6 hr at ~900°C |
Samples with:
| 6 hr or more at XXX°C |
A common program is an increase in temperature of 3°C/min to a target temperature of 900°C and a hold of one hour. Then ramp up at a rate of 3°C/min to a target temperature of 1025°C and hold for four hours. This ramp cycle is already programmed into the furnace and corresponds to 'Program 1'. To check or edit a program see additional guides attached to the furnace itself. It is also possible to run the furnace manually without a ramp up cycle. Discuss with scientists their preference
Either enter the desired temperature manually or select your program. If you are running the furnace manually, enter the desired temperature; no other buttons or steps are needed. If selecting a program, press and hold 'Run' (Fig. 46).
