Abstract: Measurements of the squalene content in oil-in-water emulsions can be used as a way of checking for problems during production. In particular, it has been found that a drop in squalene content can indicate that filtration problems occurred. Testing the squalene content in the final lots is easier than investigating the characteristics of the filter, and so a squalene assay simplifies the quality control of oil-in-water emulsions.

Abstract: A resonator arrangement has a conductive, semi-open outer housing, at an interior of which a conductive bar is provided disposed coaxially to the housing. At one end of the bar in a direction of a housing bottom, the bar has a die and, together with a dielectric and the housing bottom, forms a capacitor. The bar is short-circuited to the housing at another end, so that the bar and housing together form an LC oscillator circuit. Also disclosed is a method for analyzing a sample using a resonator arrangement.
