To run an instrument, users must first be trained. In addition to instrumentation, additional equipment is also available for use. Instrument and/or equipment training can be requested here.

The Rheometer and DMA instruments requires advanced classes prior to training. Understanding these results and developing experiments require a greater understanding of these instruments. Suggested introductory webinars are provided on their instrument pages. Webinars should be viewed prior to seeking training.

Any experiment requiring temperature ramping and/or holding a sample at an elevated temperature requires TGA sample evaluation prior to further investigation. Namely, DSC and DMA experiments can involve sample temperature manipulation. Performing experiments outside a sample’s temperature stability range can damage the instrumentation and nullify any results acquired. Therefore, all DSC and DMA experiments require TGA evaluation (for the 95% decomposition temperature) prior to acquisition on either instrument. DSC and DMA experiments should only be conducted at temperatures below the T95 (generally, Tmax = T95 – 10 °C). If users desire DSC or DMA training, TGA training is also required. Service requests for DSC or DMA sample analysis will also require TGA evaluation prior to the requested service.

The GPC systems are submission-based only. Samples should be submitted as prepared solutions in THF or HFIP (2 mg/mL), filtered (0.2 µm) and particulate free, or as pre-weighed (2-5 mg) solid material. Samples should only be submitted in well-sealed glass containers.

The Universal mechanical tester (i.e., the Tensile Tester) is submission-based only. Students are welcome to watch the analysis while is being performed, but testing must be performed by a staff member.
