    Abstract: An embodiment provides a permanent sealing assembly for a container, such as a reagent bottle. The permanent sealing assembly allows for drip-less reagent container exchange for liquid analysis instruments. The permanent sealing assembly may be integrated into a container, such as a reagent bottle, and provides an outflow tube that extends into the container. The permanent sealing assembly and the outflow tube thereof remain in the container such that, on an exchange of regent containers, a removable cap assembly of the liquid analysis instrument may be affixed to a new container of reagent without the risk of reagent from the old container contacting the surroundings. Other aspects are described and claimed.

    Abstract: A method for controlling a hydrogen sulfide concentration of a wastewater stream, the method including measuring a hydrogen sulfide concentration in one phase of the wastewater stream. At least one additional parameter of the wastewater stream is measured, and a hydrogen sulfide concentration of the other phase of the wastewater stream is calculated with a mathematical model that characterizes the hydrogen sulfide concentration in the other phase based on a set of variables that includes the measured hydrogen sulfide concentration in the one phase and the measured at least one additional parameter. Based on the calculated hydrogen sulfide concentration of the other phase, a treatment dosage of a treatment agent that reduces the hydrogen sulfide concentration of the wastewater stream is determined and applied to the wastewater stream.
