Sample Preparation
See the sample preparation instructions for the parent instrument.
Sample Pans
The types of sample pans that you can use for the DSC 4000 and DSC 6000 with
autosampler are all sizes of the standard robotics sample pans that are available. The sample
pans must be sealed using the Universal Crimper press which comes with the system. The
capacities for the sample pans are 10, 25, 30, and 50 µL.
Sample Loading
Before loading the sample into the crucibles for the TGA 4000 or STA 6000, you will have to
tare the crucibles, that is, have the system weigh them so the weight of the crucible is not
included in the data. Load the empty crucibles into the sample trays. You can do this with
the trays either separate from the autosampler or while they are still in place. After filling the
locations with crucibles, carefully place the trays back onto the autosampler, making sure
that the two “buttons” on the bottom side of each tray engage the holes in the autosampler.
If you keep the trays on the autosampler, load the sample into each crucible while it is off
the tray and then use tweezers to place the crucible onto the tray.
You can tare all of the crucibles in the tray using the Pyris Player Tare All feature. To do this,
your play list must contain a Sample Group. If you are creating a new play list, select Sample
Group as the first entry. If you are using an existing play list, it should have a Sample Group
in it in order to use the tare feature.
In a new play list, with Sample Group highlighted, click the
Tare All
button to display the
Advanced Tare Options dialog box. If you choose
This Group Only; Populate from Tray
,
the Sample List is filled with a line for each position in the trays that contains a crucible and
the tare weight of the crucible is included. You can also add sample lines yourself and then
select
This Group Only; Sample List Items Only
from the dialog box. Only the crucibles in
the positions that you selected for your Sample List will be tared.
