This Jupyter-notebook plots spectra from SpectroWorks™ and calculates the absorbance in a given range. It also calculates the particle size and concentration of samples of Titanium Dioxide.
Test A: Absorbance of TiO2
|Minimum Wavelength (nm)||Maximum Wavelength (nm)||Minimum Absorption|
Result: The absorption is calculated and a Pass / Fail result is produced.
|Calculated Absorption||Pass / Fail|
Test B: Particle Size of TiO2
Figure 2: A graph showing the distribution of particle number and particle diameter as calculated using the NanoCuvette S™ and the SpectroWorks™ software.
Description: Calculate the diameter of the particle in nm IF enough particles found within bounds of size, otherwise give NaN.
Parameters: Enter the expected diameter of TiO2 and the tolerance in nanometers.
|Diameter (nm)||Diameter tolerance (nm)|
Result: The diameter of the particles are calculated and a Pass / Fail result is produced.
|Diameter of TiO2 (nm)||Pass / Fail|
Test C: Percentage of particles of TiO2 with given size
Description: Calculate the number of particles within the desired diameter range (set above) as a percentage of total particles and test if above a minimum percentage.
Parameters: Enter the minimum percentage of particle concentration within size bounds relative to the total concentration (%).
|Particles within size bound (%)||95|
Result: The number of particles as a percentage of total particles are calculated and a Pass / Fail result is produced.
|Are there at least 95% of total particles within the diameter range 35 < d < 85 nm?||Pass / Fail|
Test D: Concentration of TiO2
Description: Calculate the total concentration of TiO2 in the sample and test if it is within the bounds of desired concentration.
Parameters: Enter the total volume in cm3 for the sample:
|Sample Volume (cm3)||1000|
|TiO2 mass in sample (g)||20|
|Density of TiO2 in sample (g/cm3)||3.78|
|Concentration tolerance percentage (%)||20|
Result: The total concentration is calculated and a Pass / Fail result is produced.
|Total Concentration of TiO2 in sample (g/l)||Pass / Fail|
