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.
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 5 ml. Some of the
combination ion electrodes will read down to just 2 ml of liquid.
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.
All ion selective electrodes in the table below are combination
electrodes where the reference electrode is already included within the body of the
ion selective electrode. Mono electrodes without the reference electrode
are also available upon request. Please contact us for
pricing and delivery. |
