Mercury flow from a reservoir of mercury to a mercury drop capillary extending vertically downward from the reservoir is governed by selective engagement of a sealing surface immersed in the mercury reservoir with a valve seat also immersed in the mercury reservoir to allow for controlled formation of mercury drops at the lower end of the capillary which drops, after formation, are held non-growing or static. The capillary is removable from the housing and when so removed the sealing surface engages the housing of the reservoir to prevent loss of mercury from the reservoir.

Static drop mercury electrode

An effluent delivery tube directs effluent from below mercury drops formed by a mercury drop electrode in a vertically upward direction coaxial to the vertical axis of the mercury drop to provide turbulent free flow of effluent about the drops. A method of analyzing an effluent stream by directing an effluent from below a drop formed by a mercury drop electrode in a vertically upward direction coaxial to the vertical axis of the mercury drop to provide turbulent free flow of effluent about the mercury drop.
