  • Only Powder, Metal, Pellet, Thin film samples can be done. No liquid samples can be done.
  • Either Low temperature (20K to 300K) or High temperature (300K to 1000K) can be done within the given range. No measurement can be done in a single stretch starting from 20K to 1000K.
  • For Powder sample minimum sample required is 100 mg.
  • For thin film samples the dimension should be 10 mm x 4 mm (length x breadth).
  • For High temperature measurements only Pelletized form of samples can be done.
  • The users should fill up the form (downloadable from the 'Forms' page) and submit it with the sample
  • Each sample has to be listed separately.
  • External samples will be analyzed in que at a fixed rate.

Payments

  • External users, please bring a draft in the name of  Registrar, IIT Madras  for the appropriate amount.
