Applicant's summary and conclusion
- Conclusions:
- The particle size distribution (granulometry) of sodium 4-aminonaphthalene-1-sulphonate by the sieve analysis method was found to be in the range of 53 micrometer to 300 micrometer. Majority of the particles were found to be in the size range of 300 to 500 micrometer.
- Executive summary:
The particle size distribution (granulometry) of sodium 4-aminonaphthalene-1-sulphonate by the sieve analysis method was found to be in the range of 53 micrometer to 300 micrometer. Majority of the particles were found to be in the size range of 300 to 500 micrometer.
