Peroxidase determn. in enzyme immunoassay (EIA)-- use four: hydrogen donor of the alkyl-benzidine as chromogenic element

摘要

In order to enable the drawing-off of residual vapours of a low-boiling liquid from a pressure system (1) into a storage vessel (2), the pressure between said system and the storage vessel is first equalized, whereafter the presure in the storage vessel is reduced and the pressure in the pressure system increased, enabling thus passage of the low-boiling liquid with its vapours in the liquid state into the storage vessel. This process can be repeated in order to draw-off liquid with its vapours from the pressure system.
