Standards, Calibration and Guidelines in Microcalorimetry

Project No.:120-18-97
Start date:1997-01-01
End date:2001-12-31
Division:Physical and Biophysical Chemistry Division
Objective:

Microcalorimeters are now employed in a wide variety of fields in medicine, food and biological studies, in addition to those where there are more traditional areas. The instruments are now manufactured commercially by a number of organisations worldwide and used by individuals and organisations with absolutely no expertise in the field. Since all microcalorimeters require calibration there is evidently an immediate need for some common standards and they do not exist at present. For the most part calibration have been carried out electrically, but the future will undoubtedly require other calibration systems such as chemical or biological calibrants. It is proposed to recommend such standards and procedures that are suitable. Further it is proposed to seek to define those properties of microcalorimeters that should be used to characterise performance. This is vital so that the merits of the instruments produced by different organisations can be compared in a rational way.

Progress:
The project consists of two parts:
  • Isotherm microcalorimetry[coordinator: I.Wadsö]
  • Temperature scanning (micro)calorimetry[coordinator: G.Della Gatta]

    • Thisproject was presented at a postersession at the IUPAC Congress/GA July 2001
