Summary

A NEW VERSION OF A SQUID SUSCEPTOMETER IS PRESENTED. THE SAMPLE CAN BE INTERCHANGED IN MINUTES AND THE OVERALL TIME TAKEN BY THE ACTUAL MEASUREMENT PROCEDURE, TO GIVE RESULTS WITH HIGH ACCURACY, IS OF THE ORDER OF 5 MIN FOR ONE SAMPLE AT ONE TEMPERATURE. THE TEMPERATURE REGULATION IS PRECISE WITHIN 0.2 K BETWEEN 40 AND 300 K ; THE ACCURACY IN THE SAMPLE TEMPERATURE HAS BEEN TESTED TO BE WITHIN 0.5 K IN THE ROOM TEMPERATURE RANGE. THIS PERFORMANCE IS OF GREAT RELEVANCE FOR STUDIES OF BIOLOGICAL MOLECULES IN SOLUTION, WHEN DIFFERENT SAMPLES IN DIFFERENT SOLUTION CONDITIONS MUST BE COMPARED.
