Oct 28, 2015 - Standards
Sample Prep
~120-130 ppm standards were prepared
- Sodium pyrophosphate ( Na4P2O7) from Sigma Aldrich 0.123g to 100g DI water
- Sodium Polyphosphate ( SHMP) from Sigma Aldrich 0.0128g to 100g DI water
- Sodium Hexametaphosphate (Hexaphos)from ICL Performance Products LP 0.0126g to 100g DI water
- Sodium Acid Metaphosphate from ICL Performance Products LP 0.0129g to 100g DI water
- Sodium Phosphate ( H2NaPO4) from Acros Organics 0.0133g to 100g DI water
- Sodium Hexametaphosphate (Sodaphos) from ICL Performance Product LP 0.0119g to 100g DI water
- Sodium Tripolyphosphate (Na5P3O10) from Sigma Aldrich 0.0121g to 100g DI water
- Sodium Trimetaphosphate ((NaPO3)3) from Alfa Aesal 00120g to 100g DI water
Results
- Samples were filtered through 0.45 µm filter
- Instrument was equilibrated for 49 minutes and auto-zeroed
Conclusions
- UN-SCAN-IT 6.0 was used to convert chromatographs into data < data was plotted in excel < Excel graphs were compared to assign retention times to phosphate species.
