Connect the electrode to the sensor or measuring
device.
2. Prepare two standard solutions that differ in
concentration by a factor of ten and bracket the
expected sample concentration range. Use the con
-
centration unit that is most appropriate. The
standards are at the same temperature as the
sample.
Measurement:
If using a measuring devicewith direct concentration
reading capability see the software on-line help or the
measuring device’s instruction manual for specific
information:
1. Place 100 mL of the low standard into a 150 mL
beaker. Add 2 mL of ISA. Stir thoroughly.
2. Rinse electrode with Dl water, blot dry and place in
the beaker. Wait for a stable reading, and then
adjust the measuring device to display the value of
the standard. Refer to the software on-line help or
the measuring device’s instruction manual for the
adjustment procedure.
3. Measure 100 mL of the high standard into a second
150 mL beaker. Add 2 mL of ISA and stir.
4. Rinse electrode with Dl water, blot dry and place in
the second beaker. Wait for a stable reading, and
then adjust the measuring device to display the
value of the second standard.
5. Pipette 100 mL of sample into a 150 mL beaker. Add
2 mL of ISA. Stir thoroughly.
6. Rinse electrode with Dl water, blot dry and place in
the sample beaker. Wait for a stable reading and the
sample concentration will be displayed on the mea
-
suring device.
7. Determine the sample concentration using the data
analysis tools in the software.
Electrode Storage
Short Term (over night or the weekend):
Rinse the electrode thoroughly with Dl water and place
the tip in a diluted standard solution between
measurements. Slide the FastFil sleeve upward to close
the fill hole.
Refill the reference before putting the electrode back into
service
Long Term
Refill the electrode with Reference Filling Solution and
close the fill hole. Remove the sensing element and
store in the glass vial or replace the cap to protect the
sensing element.
Follow procedures in "Electrode Preparation" and
"Checking Electrode Operation" before using the
electrode again.
