Modulations, multi-component analysis

The tools for the analysis of the glass transition are developed in Chap. 4 and general descriptions are given in Sect. 6.1.3. In Sect. 7.3, finally, thermal analysis is applied to the study of the glass transition in multi-component systems. In the present section time-temperature effects are reviewed first (Sect. 6.3.1). This is followed by a description of modeling by using temperature-modulated DSC (Sect 6.3.2). Finally, applications to the study of pressure and strain, crystalhzation, and network formation are treated in Sects. 6.3.3-S, respectively. 

Table 1.2 gives some of the reasons for the LGC setting up its automation team. The primary motivation was economic. LGC was often subject to constraints on staffing in parallel with large increases in analytical commitments. The introduction of cost-effective analyses, using mechanical or automatic instruments, reduces staff involvement and allows well qualified people to be released for the development of new analytical requirements. The analysis of beer samples by multi-channel continuous flow analyser [S, 6, 7] and the introduction of a mechanical solvent extraction and identification system to analyse and measure levels of quinizarin in gas oil, both for duty purposes, were prime examples [8], Both systems involved commercially available components and/or instruments integrated with modules designed and built in-house.
