摘要： To detect contamination in used PET returnable bottles, they are fed to a first testing station which takes a gas sample from each bottle. This first testing station tests for the presence of heavy contamination. Heavily contaminated bottles are identified as dirty. The bottles are then fed to a second testing station which takes gas samples from the clean bottles and tests them for contamination with a lower detection threshold. Bottles detected here as contaminated are removed, as are the bottles which fail the first test. The two-stage process allows testing with greater sensitivity while maintaining a high bottle throughput.

摘要： Inspection of PET bottles for contamination is performed with a mass spectrometer in which the gas sample is ionized by an ionized primary gas. This causes greatly reduced fragmentation, or unambiguous fragmentation, of the gas sample. As a consequence, the spectrum obtained is very meaningful on its own, and can be interpreted very rapidly, which is an essential prerequisite for the use of mass spectrometers in industrial inspection.

摘要： The sample and the reagent required for titration are fed into a titration vessel (1), the reagent and/or sample being supplied intermittently in the form of pulses of liquid. Toward this end, a controlled valve (9) is provided in the supply line (4) for the reagent. The opening and closing times of this valve (9) and, hence, the frequency and duration of the pulses of liquid, are chosen such that the ratio of the average sample flow to the average reagent flow is sufficient to achieve the ratio of sample to the reagent at the equivalence point. This renders continuous titration possible, for which only one pump (7) is needed, which does not require any complex servo system and, therefore, has a low energy consumption.

摘要： An apparatus and method for the indirect determination of concentrations of additives in metal plating electrolyte solutions, particularly organic additives in Cu-metalization baths for semiconductor manufacturing. The apparatus features a reference electrode housed in an electrically isolated chamber and continuously immersed in the base metal plating solution (without the additive to be measured). An additive concentration determination method comprises electroplating a test electrode at a constant or known current in a mixing chamber wherein the base metal plating solution is mixed with small volumes of the sample and various calibration solutions containing the additive to be measured. Plating potentials between the electrodes are measured and plotted for each of the solution mixtures, and data are extrapolated to determine the concentration of the additive in the sample. A multi-cycle method determines the concentration of both accelerator and suppressor organic additives in Cu plating solution in a single test suite.
