Removing the Lid to Pressure Chamber

Chamber must be purged of gas before trying to remove lid due to pressurization.

Removing Final Cell Lid

There are many lids protecting the analysis area

The Two Thermal Pedestals

This is where you place your sample material. One pedestal is left unused as a control. The difference in energy between the two to keep them at the same temperature is plotted in a graph for analysis.

My Samples

I used a small hole punch to create samples with little variation.

A Look at the HDPE After Analysis

It has melted and resolidified.

A Sample of Analysis Output

This depicts the energy input as the material was heated, cooled, and heated again. From this, I can use linear regression to estimate the melting temperature.

My Final Poster

Unfortunately, this is the only picture of it. I wish it were more clear.
