Abstract

Electrochemical cell array for the treatment of a sample via electro-(end-)osmotic flow, comprising (i) an electrode chamber, comprising a cathodic compartment (CC) and an anodic compartment (AC), (ii) a cathode (C), being arranged in the cathodic compartment (CC), (iii) an anode (A), being arranged in the anodic compartment (AC), (iv) an intermediate cathodic compartment (C1) (v) an intermediate anodic compartment (A1) (iv) a first selective membrane (M1) being arranged between said cathodic compartment (CC) and said first intermediate cathodic compartment (C1) (v) a second selective membrane (M2) being arranged between said anodic compartment (AC) and said first intermediate anodic compartment (A1) (vi) a treatment compartment (T) for the sample being arranged between said intermediate cathodic compartment (C1) and said intermediate anodic compartment (A1), further comprising a first separator membrane (S1) between said treatment compartment (T) and said intermediate cathodic compartment (C1) and a second separator membrane (S2) arranged between said treatment compartment (T) and said intermediate anodic compartment (A1).

Dependent claims

An electrochemical cell for the treatment of a sample via electro-(end-)osmotic flow, comprising:

(i) an electrode chamber,
(ii) a cathode, being arranged in a cathodic compartment of said electrode chamber,
(iii) an anode, being arranged in an anodic compartment of said electrode chamber,
(iv) an intermediate cathodic compartment,
(v) an intermediate anodic compartment,
(vi) a first selective membrane being arranged between said cathodic compartment and said first intermediate cathodic compartment,
(vii) a second selective membrane being arranged between said anodic compartment and said first intermediate anodic compartment, and
(viii) a treatment compartment for the sample being arranged between said intermediate cathodic compartment and said intermediate anodic compartment, further comprising a first separator membrane between said treatment compartment and said intermediate cathodic compartment and a second separator membrane arranged between said treatment compartment and said intermediate anodic compartment,
wherein the first separator membrane and the second separator membrane are electro-(end-)osmotically active membranes, and
wherein the first separator membrane and the second separator membrane comprise a gel.
