17. Based on the control type selected, enter method parameters as follows:
a. Scroll and select the desired ramp time minutes (0 – 60 minutes).
b. Scroll and select the desired ramp time seconds (0 – 59 seconds).
c. Scroll and select the hold time minutes (0 – 60 minutes).
d. Scroll and select the hold time seconds (0 – 59 seconds).
e. Scroll and select the desired temperature (0 – 300 ºC in increments of 1).
f. Scroll and select the desired pressure (0 – 800 psi in increments of 50).
g. Scroll and select the desired temperature delta (0 – 50 C in increments of 5) –
when using Evaporation only
h. Scroll and select the desired power (0 - 1800 watts in increments of 10).
i. Toggle the stirring option to the desired setting (on or off).
Note:
General guidelines for 100% power are as follows:
1 - 2 Framed Vessels
400 watts
8 – 12 MARS Xpress Vessels
800 watts
3 - 6 Framed Vessels
800 watts
13 – 20 MARS Xpress Vessels
1200 watts
7 - 12 Framed Vessels
1600 watts
21 – 40 MARS Xpress Vessels
1800 watts
Note:
Based on the vessel type chosen for the method, the instrument will allow the user to scroll only from the minimum
to the maximum pressure and temperature. If no control is selected, the instrument will not accept any pressure or
temperature. The following table indicates the maximum pressure and temperature for each vessel which can be utilized
in the MARS 6 instrument.
