Thermal lag caused by poorly heat-conductive samples results in nonlinear temperature gradients during non-isothermal DSC measurements in the absence of thermal events

Key Points

• Nonlinear temperature gradients arise from significant thermal lag in samples, impacting measurement reliability.
• The observed variation in temperature was notably affected by the heat-conductive properties over several trials.
• Observational analysis across multiple conditions indicated that poorly heat-conductive samples led to inaccurate thermal readings.
• These findings highlight measurement inaccuracies, necessitating better sample selections for reliable non-isothermal DSC measurements.
