Product Details
| Product Code | 607400 |
| Contents | Indicator, 6 mL Titration Solution, 15 mL Test Tube, 10 mL Instructions for Use |
| Analytical Method | Alkalimetric Titration: The water sample is titrated with sodium hydroxide to the pH of 8.2 against a pH indicator (phenolphthalein). |
| Number of Tests | 50 – 80 |
| Interferences | This test is suitable for natural waters not high in total dissolved solids. Positive interferences are caused by metal ions that precipitate in alkaline solution (aluminium, chromium, copper, iron), as well as by weak bases (ammonia, amines) and salts of weak acids and strong bases (borate, nitrite, phosphate, silicate, sulphide). Such substances should not exceed 5 % of the carbon dioxide concentration. This test is not suitable for seawater. |
| Measuring Range | The recommended measuring range is 40 to 400 mg/L (2 – 20 drops @ 20 mg/L) for 5 mL of sample volume. This range can be extended by taking a smaller or larger water sample. For a 2.5 mL sample the measuring range is 80 to 800 mg/L and for a 10 mL sample the range is 20 to 200 mg/L. |
| Shelf Life | 2 years |
| Applications | Determination and monitoring of carbon dioxide levels of ground water (bore water) and in aquaculture. |
