temperature possible without sample degradation. Most runs should not come

within 25 °C of the T

 When choosing a method, determine if the method is appropriately made. Runs

should mostly look like the following:

o Dynamic Segment (heating or cooling)

o Dynamic Segment

o Isothermal Segment @ end temperature of the dynamic segment for 2-5 m

o Dynamic Segment

o Isothermal Segment @ end temperature of the dynamic segment for 2-5 m

o Dynamic Segment

o Isothermal Segment @ end temperature of the dynamic segment for 2-5 m

o Dynamic Segment

o Isothermal Segment @ end temperature of the dynamic segment for 2-5 m

o Dynamic Segment back to room temperature

 When creating a new method/modifying an old method, make sure that the end

temperature of one segment matches the start temperature of the next segment.

 The maximum temperature for the instrument is 500 °C.

7. Sample Preparation:

 Weigh out the sample in an aluminum pan. The weight should be between 3-10

mg.

 Once weighed out, bring the sample to the press and place the pan in the press

holder.

 Place the hat (top half of the DSC pan) onto the pan. It should sit in fairly easily.

 Place the press holder in the press and crimp the pan.

 OPTIONAL: Using the pin in the DSC box, poke a small hole in the top of the

pan. You do not need to stab the pan, light force is sufficient in poking the pan.

8. Once a method is selected, place a sample name into the field. Sample name should be

placed as follows: YYMMDD_NOTEBOOK CODE_DSC

Place the weight of the sample in the box and place the sample into the DSC on the left

side. DO NOT TOUCH THE BLUE SENSOR WITH THE TWEEZERS! The position

does not matter. Click Send Experiment.

 The DSC does not have an auto sampler.

 Make sure the reference pan matches the sample pan. If the sample pan has a hole

in the top, the reference pan should also have one. If the sample does not have a

hole, the reference should match.
