Apparatus for determining the amount of volatile impurities in a liquid material and method for using the same

摘要

The invention relates to an apparatus (22) with a hermetically sealable measuring chamber (8) comprising a bottom part (5), a chamber part (6) and a measuring part (7) with a closable opening (1) for introducing a liquid material (11) into the measuring chamber (8). The bottom part (5) is moveably arranged in the chamber part (6) and configured to reduce the pressure in the measuring chamber (8) to a predefined pressure such that the volatile impurities are released over a free surface of the liquid material as gas bubbles (12) which collapse leaving a gas volume. The measuring chamber (8) further comprises a transparent panel (9) for determining the gas volume. Moreover, the invention relates to a method for using the apparatus (22).
