在Lazar微型PH電*成功使用后，Lazar研究實(shí)驗(yàn)室有限公司開發(fā)了一系列的微離子電*，它們至今被全世界各個(gè)研究中心使用。我們的離子電*可測(cè)量*低10微升
特點(diǎn)：
1、靈敏度高：大多數(shù)低于1 ppm的離子都可以被測(cè)量。一些離子如銅(+2)檢測(cè)范圍可*低達(dá)到十億分之一。
2、快速回應(yīng)時(shí)間：由于薄膜的上等設(shè)計(jì)，選擇離子參數(shù)時(shí)，離子濃度變化的響應(yīng)速度非?？?，典型的響應(yīng)速度時(shí)間是30秒。
3、寬泛的濃度范圍：電*偵查離子的范圍在百萬分之一至幾千ppm。一些電*可以檢測(cè)1摩爾的濃度。
4、抗體：電*可以使用在酸、堿和一些溶劑中。
5、便于攜帶的：不需要回到實(shí)驗(yàn)室，可以當(dāng)場(chǎng)測(cè)量。
6、小樣本測(cè)量：可測(cè)量10微升的小樣本。
7、閱讀快速輕松：電*可以與任何手提式打字機(jī)或者實(shí)驗(yàn)室PH毫伏表使用。
8、直接銜接：我們的電*可以直接插入你的PH 毫伏表。不存在不兼容問題。
一些離子電*可用于核磁共振管：
完整的微型離子測(cè)量系統(tǒng)集測(cè)量、記錄、制圖于一體。系統(tǒng)包括：計(jì)量?jī)x、離子電*、**電腦制圖軟件。
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
