5. How to check the proper functioning of the µDSC 7 Evo ?

Start a series of blanks to check the drift
Pre-stabilization at -10 ° C by direct programming with a water temperature of about 30 ° C.
Phase 1: -10 ° C → 115 @ 1 ° C / min, 115 → 30 ° C @ 1 ° C / min, Phase 2: 3600s at 30 ° C
  Drift (mW) <1.1
  Background noise (μW) <2.2
Then do a naphthalene control fusion.
30 ° C → 50 ° C @ 1 ° C / min, 50 ° C → 90 ° C @ 0.7 ° C / min
Stabilization prior to 30 ° C by direct programming.
Melting temperature (° C) 80.25 ± 0.42
Melting enthalpy (J / g) 147.6 ± 2.6
