    • A pH sensor (120) for a single-use bioreactor (51) is provided. The sensor (120) includes a pH sensing electrode (146), a reference system, a storage compartment (150), and an access mechanism. The reference system includes a reference electrolyte (142), a reference electrode (144) disposed in the reference electrolyte (142), and a reference junction (152). The storage compartment (150) contains a storage solution (160) that is configured to contact the pH sensing electrode (146) within the storage compartment (150). The access mechanism is configured to, when actuated, couple the pH sensing electrode (146) to an interior of the single-use bio-reactor (51). The storage solution (160) includes a buffer solution that is compatible with the reference electrolyte (142).
    • 提供了用于一次性生物反应器(51)的pH传感器(120)。 传感器(120)包括pH检测电极(146),参考系统,储藏室(150)和存取机构。 参考系统包括参考电解质(142),设置在参考电解质(142)中的参考电极(144)和参考结(152)。 存储隔间(150)包含存储溶液(160),其配置成接触储存室(150)内的pH感测电极(146)。 进入机构被构造成当致动时将pH感测电极(146)耦合到一次性生物反应器(51)的内部。 存储溶液(160)包括与参考电解质(142)相容的缓冲溶液。

    • Herein is disclosed a method for detecting pH, the method comprising: providing an electrode comprising a carbon material having at least one plane of carbon atoms, wherein the plane of carbon atoms has been oxidised at its edge, such that quinone structures or hydroquinone structures form part of the plane, contacting a sample with the quinone or hydroquinone structures of the plane of carbon atoms, carrying out an electrochemical test to reduce the quinone structures or oxidise the hydroquinone structures and determine the potential at which the reduction of the quinone structures occursor at which the oxidation of the hydroquinone structures occurs, using the potential at which the reduction or oxidation occurs to calculate the pH of the sample.. An apparatus for carrying out the method for detecting pH is also disclosed herein.
