Dear All,

I need to use 80% Ethylene Glycol for high temperature calibration.

Before I do the calibration, I compared it with 99.8% MeOD at 303 K.

When I set temperature to 303 K,
99.8% MeOD gives 303.03 K while 80% Ethylene Glycol gives 300.57 K
The difference between the two calibration samples is 2.46 K.

Is this normal?

Your comments are appreciated!

Best regards,
