E133 - Briliant blue
Exploratory experiments
The goal is to evaluate the concentration required to have an absorbance of around 0.5.
We took 427.0 mg in 100mL of water.
From this we placed 0.5mL in 100mL.
21 mg/L
| Color | Absorbance | Emission |
|---|---|---|
| Red | 1.04 | |
| Green | 0.04 | |
| Blue | 0.10 | |
| UV | 0 |
10.5 mg/L
| Color | Absorbance | Emission |
|---|---|---|
| Red | 0.61 | |
| Green | 0.05 | |
| Blue | 0.01 | |
| UV | 8 |
Conclusions
We need around 9 mg/L to have an absorbance in red of around 0.5.
