So you've used your DSC to measure loads of samples - but did you calibrate it first? I hope so, otherwise you can't trust your data! Calibration is quick and easy and if you don't know how it's performed, then this video will explain it all!
Calibration is designed to improve accuracy of measurement - NOT precision! If you are not clear on the difference between accuracy and precision, then the link below will take you to a helpful video;
Are accuracy and precision the same thing? https://youtu.be/BU9UhCMS99c
If you want to delve deeper into the design considerations of DSC, there are several excellent reference sources you might look at. I would recommend;
