Injection speed materials data

To demonstrate the linear response of the High Speed Sulfur Analyzer, a 750.1 mg/kg reference diesel sample was diluted eight times sequentially on a 1 1 basis with a near-zero sulfur light hydrocarbon of similar density. Each of the nine samples was injected multiple times in a HSS series analyzer that was set for a 1000 ppmw full scale range and calibrated with the neat reference material. The data are summarized in Table 4, and the correlation is plotted in Fig. 10. The r2 correlation coefficient was 0.999. The data in Table 4 indicate a % RSD of better than 10.1 % in the 4-28 mg/kg sulfur range. At the higher sulfur levels, between 50-750 mg/kg, the %RSD is between 4-0.6%. Figure 10 illustrates the correlated linearity data. 

The need for high deformation speeds leads to the use of shorter tensile specimens than usual. The specimen used for the results presented in this paper is presented on the right side of fig. 3. For short-fiber reinforced materials the tensile specimens are not directly injection-molded. Instead they are milled out of plates that are filled by a film gate with an almost parallel melt front. So stiffness and strength data along and transverse to the predominant fiber orientation can be measured.
