Title: Standards, Calibration and Guidelines in Microcalorimetry

Coordinator(s): I.Wadsö and G. Della Gatta


Completion Date: 2001 - project completed

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.

The project consists of two parts:

  1. Isotherm microcalorimetry [coordinator: I.Wadsö]
  2. Temperature scanning (micro)calorimetry [coordinator: G. Della Gatta]

This project was presented at a poster session at the IUPAC Congress/GA July 2001

Final drafts of these papers have been prepared, and they are now being reviewed for publication.
