Our family of
Ion-Selective Electrodes are
great for monitoring four
environmentally important ions:
Nitrate (NO3-),
Chloride (Cl-),
Calcium (Ca2+), and
Ammonium (NH4+).
Here are some of
their features:
- Electrodes are
combination-style,
non-refillable, and
gel-filled.
- It is important for you to
know that Vernier ISE
membranes, like all other
PVC ISE membranes, have a
limited life expectancy;
however, the replaceable
module of Vernier ISEs
allows you to simply discard
the used one, and replace it
with a new
module. We recommend
that you do not purchase
replacement modules far in
advance of their expected
time of use, as their life
expectancy is limited as
well.
- Included with each ISE are
two calibration
standards and a
Short-Term Soaking Bottle.
| Here
are some uses of each of
our four electrodes: |
| Nitrate
(NO3-) |
Nitrate ion
concentration is an
important parameter in
nearly all water quality
studies. Nitrates can be
introduced by acidic
rainfall, fertilizer
runoff from fields, and
plant or animal decay or
waste. |
| Chloride
(Cl-) |
This ion
gives a quick
measurement of salinity
of water samples. It can
even measure chloride
levels in ocean
saltwater or salt in
food samples. |
| Calcium
(Ca2+) |
This
electrode gives a good
indication of hardness
of water (as Ca2+).
It is also used as an
endpoint indicator in
EDTA-Ca/Mg hardwater
titrations. |
| Ammonium
(NH4+) |
This
electrode measures
levels of ammonium ions
introduced from
fertilizers. It can also
indicate aqueous ammonia
levels if sample
solutions are acidified
to convert NH3
to NH4+. |
