在Lazar微型PH电*成功使用后，Lazar研究实验室有限公司开发了一系列的微离子电*，它们至今被全世界各个研究中心使用。我们的离子电*可测量*低10微升
特点：
1、灵敏度高：大多数低于1 ppm的离子都可以被测量。一些离子如铜(+2)检测范围可*低达到十亿分之一。
2、快速回应时间：由于薄膜的上等设计，选择离子参数时，离子浓度变化的响应速度非常快，典型的响应速度时间是30秒。
3、宽泛的浓度范围：电*侦查离子的范围在百万分之一至几千ppm。一些电*可以检测1摩尔的浓度。
4、抗体：电*可以使用在酸、碱和一些溶剂中。
5、便于携带的：不需要回到实验室，可以当场测量。
6、小样本测量：可测量10微升的小样本。
7、阅读快速轻松：电*可以与任何手提式打字机或者实验室PH毫伏表使用。
8、直接衔接：我们的电*可以直接插入你的PH 毫伏表。不存在不兼容问题。
一些离子电*可用于核磁共振管：
完整的微型离子测量系统集测量、记录、制图于一体。系统包括：计量仪、离子电*、**电脑制图软件。
Micro Ion Electrodes
After the success of the Lazar micro pH electrode, Lazar Research Laboratories, Inc. developed a series of micro ion electrodes which are used today by research centers worldwide. Our micro ion electrodes measure ions down to 10 micro liters.
Features:
High Sensitivity: Most ions can be measured to below 1 ppm. Some ions such as copper (+2) can be measured down to the low part per billion range.
Fast response time: Due to membrane design parameters ion selective have a rapid response to changing ionic concentration. Response time of 30 seconds is typical.
Broad concentration range: Electrodes will detect ions down to the low part per million range up to several thousand ppm. Some of the electrodes will measure up to a concentration of 1 Molar.
Resistant Body: Makes electrodes usable in acids, bases and some solvents.
Portable: On-the-spot field measurements can be made without a trip back to the laboratory.
Small Samples: Measures samples as small as 10 micro liters.
Quick and Simple Readings: The electrodes can be used with any portable or laboratory pH/millivolt meter.
Direct Plug: Our electrodes plug directly into your pH/millivolt meter. No compatibility problems.
Some micro ion electrodes also available for NMR tubes - see below
