This is equivalent to a cell productivity of 5 g/liter-hr. When the shots were being added every five minutes, some triple shot doses were required to meet the demand. This meant that 39 g of ethanol were being added essentially instantaneously. This could result in a brief period where the ethanol concentration reached 1 g/liter. Since this bordered on being undesirable, 2 minute control intervals were selected in the latter runs. This meant that there would never be more than a double shot, i.e. 26 g alcohol/40 liters added to the vessel. These conditions were expected to avoid acetate accumulation. This was borne out in the hourly gas-chromatograph analysis of the broth. At the end of the run the acetate was found to be less than 0.1 g/liter.

Two-shot injection molding n. Confusingly, this term has been used in the literature for two processes that are distinctly different. One is described under double-shot molding. In the other process, one first injects a metered amount of one material into a single-cavity mold. As this material just begins to chill against the cold mold surfaces, a second material is injected. This fills the interior and forces the first material outward to the cavity surfaces. The second polymer, usually a reclaimed material forms the interior of the finished article, while the virgin material first injected forms the outer shell and surface of the article.

The term coinjection can denote different products, such as sandwich construction, double-shot injection, multiple-shot injection, structural foam construction, two-color molding, and inmolding. Whatever its designation, a sandwich configuration has been made in which two or more plastics are laminated together to take advantage of the different properties each plastic contributes to the structure. 

Kodama et al [805] have analysed antioxidants in vulcanised SBR compounds using heat-desorption by means of a double-shot pyrolyser followed by GC-MS analysis. Schulten et al [675] performed TPPy-FIMS experiments using direct introduction. Rubber vulcanisates (BR, NR, SBR) were heated without any pretreatment from 50°C to 750°C in high vacuum with a heating rate of 1.2°C s mass range recorded 50-1500 Da. Figure 2.41 shows the thermogram for some pyrolysis products for BR. The counts (in arbitrary units) for the total ion current, butadiene (m/z 54), butadiene dimer (m/z 108), mercaptobenzothiazole (MBT) (m/z 167),...
