    摘要： A low maintenance reference electrode has a liquid junction body with a multiplicity of micron-sized capillary channels extending through the body for transporting electrolyte to a test solution. A viscosity-increasing agent thickens the electrolyte to limit its flow to a rate on the order of microliters/day so that a few milliliters of electrolyte suffice to provide an extended electrode life.

    摘要翻译： 低维护参考电极具有液体接合体，其具有延伸穿过主体的多个微米级毛细通道，用于将电解质输送到测试溶液。 粘度增加剂使电解液增稠以将其流动限制在微升/天的数量级，使得几毫升的电解液足以提供延长的电极寿命。

    摘要： Temperature compensation for ion-selective electrodes is obtained by positioning a temperature-measuring element in a chamber of limited thermal mass which is in thermal contact with the measuring electrode filling solution but is thermally isolated from other filling solutions in the electrode. In a preferred embodiment, the temperature-measuring element comprises a thermistor enclosed within thin flexible tubing; the electrical leads of the thermistor are forced against a segment of the inner wall of the tubing by an elongated strand of material abutting the thermistor to enhance heat transfer with the thermistor.

    摘要翻译： 离子选择电极的温度补偿通过将温度测量元件放置在与测量电极填充溶液热接触但与电极中的其它填充溶液热隔离的有限热质量室中来获得。 在优选实施例中，温度测量元件包括封装在薄柔性管内的热敏电阻; 热敏电阻的电引线通过与热敏电阻邻接的细长材料束而被迫靠在管道的内壁的一段上，以增强与热敏电阻的热传递。

    摘要： A marker molecule for monitoring cleaving enzyme activity is disclosed. The marker molecule includes a protein, a peptide, or an oligonucleotide. A co-factor is conjugated to the protein, the peptide, or the oligonucleotide, thereby forming a co-factor labeled protein, a co-factor labeled peptide, or a co-factor labeled oligonucleotide. The co-factor is adapted to produce an enzymatic signal that is optically detectable.
