Facility Features, Working Principle and Specifications
Facility Description
Heat Flux DSC
A technique in which the sample and reference crucible are heated uniformly (under the same conditions) with a definite amount of heat. The difference in temperature between the sample and the reference material gives the heat capacity of the sample and is measured as a function of time and temperature.
DSC is a thermal analytical technique that looks at how a material’s heat capacity (Cp) is changed by temperature. It measures the amount of heat released or absorbed by a material and hence DSC enables the measurements of the transition such as the glass transition, melting, and crystallization.
Instructions for Registration, Sample Preparation, User Instructions and Precautionary Measures
- Only online registration through the SAIF webpage will be accepted.
- Slots will be provided as per the queue. If the appointment is given but the user cannot come, a mail should be immediately sent to [at] iitb [dot] ac [dot] in to cancel his/her slot.
- Data will be sent to the registered mail ID. USB drives are not allowed due to computer virus problems.
- MSDS form has to be filled and uploaded.
- External users have to upload proof of payment.
- At least 30-40 mg of sample should be submitted.
- Sample size should be < 5mm in diameter and < 2.5mm in thickness.
- Samples containing halogens should not be sent and will not be accepted for analysis.
- Samples should not be toxic or hazardous.
- Heating program should be less than the decomposition temperature.
Samples containing corrosive substances that will react with Aluminium/Platinum/Ceramic pans should not be sent for analysis by DSC.
Charges (including 18% GST) *For Thermal Analysis, standard ramp is 10 ℃/min. Heating rates less than standard rate will be charged by hours.
