Pro ce dure
1.
Fill test tube (0778) to 10 mL line with Demineralized Water
(1151).
2. Fill the 1.0 mL Titrator (0376) to 0 mark with sample water. Wipe
any excess water off the Titrator.
3. Dispense 0.5 mL of sample water into test tube by depressing
plunger until tip is at 0.5 mark. Discard remaining water in Titrator.
4. Add 3 drops of *Salinity Indicator Reagent A (7460). Cap and
gently swirl to mix.
5. Fill 0-20 Direct Reading Titrator (0378) with *Salinity Titration
Reagent B (7461). Insert Titrator in hole of test tube cap.
6. While gently swirling the tube, slowly depress plunger to titrate
sample until yellow color changes to pink-brown. Read test result
directly from the scale where the large ring on the Titrator meets
the Titrator barrel. Each minor Titrator division = 0.4 ppt Salinity.
EXAMPLE:
Plunger tip is 3 minor divisions below 10, test result is
10 plus (3 x 0.4) = 11.2 ppt.
