Thermal anal. and calorimetry share a close relationship in the field of thermal research. With regards to the sp. heat capacity, researchers have been able to realize absolute measurement techniques by utilizing drop, conduction, and adiabatic methods that are used in calorimetry. Furthermore, it is possible to optimize differential scanning calorimetry, which is a comparative measurement technique for the sp. heat capacity used in thermal anal., by improving the absolute measurement techniques. At the National Metrol. Institute of Japan (NMIJ), we developed a new certified reference material (CRM) for comparatively measuring the sp. heat capacity, the single-crystalline silicon-NMIJ CRM 5806a, using a new type of cryogenic adiabatic calorimeter equipped with a pulse-tube refrigerator working at from 50 to 350 K. This CRM was produced in accordance with the quality specifications of NMIJ, and complies with the ISO/IEC 17025, ISO 17034, and ISO GUIDE 35 standards This paper reports on the procedure for fabricating this CRM and using it to perform sp. heat capacity measurements at low temperatures The sp. heat capacity was measured using a differential scanning calorimeter at from 280 to 340 K. NMIJ CRM 5806a was used to calibrate the heat flow. It was found that the uncertainty evaluation became easier because one factor of the uncertainty evaluation could be removed using the CRM. We show that the development of the CRM using the adiabatic calorimeter has led to an improvement in the sp. heat capacity measurement results obtained by the differential scanning calorimeter. The experimental process involved the reaction of Phenyl Salicylate(cas: 118-55-8).Category: esters-buliding-blocks
