Alkalinity TA Visocolor ECO Test Kit
Instruction Manual
Test kit for the photometric determination of total alkalinity (acid capacity)
Method:
Alkalinity (acid capacity / acid binding capacity) describes the capability of
water to neutralize acids with a pH range of up to 4.3.
The capability results from the sum of all bases (hydroxide ions) and buffers
(carbonates, phosphates, etc.).
The photometric determination of alkalinity uses bromophenol blue as an
indicator.
Measurement range
0.4–17.5 °e
5–250 mg/L CaCO3
Contents:
sufficient for 100 tests
23 mL TA- 1
2 x 50 NANOFIX TA-2
1 syringe 5 mL
1 syringe 1 mL
2 tips for syringe 1 mL
1 instruction leaflet
Hazard warning:
Information regarding safety can be found on the box label and in the safety
data sheet. You can download the SDS from www.mn-net.com/SDS.
Procedure
Required equipment: Test tubes 16 mm OD (REF 91680)
- Rinse the test tube several times with the test sample and fill it with a 5 mL sample (syringe 5 mL).
- Place the test tube in the photometer and measure ZERO.
- Add 0.2 mL TA-1 (syringe 1 mL + syringe tip)
- Add 1 NANOFIX TA-2, close, and shake vigorously.
- Clean the outside of the test tube and measure after 2 min.
- Rinse and close the tubes after use. The method can be applied also to the analysis of seawater.
To achieve more accurate results, the usage of pipettes is recommended.
