The authors do a calibration, then analysis of Breakfast Cereals for Calcium content. Analysis samples were cryogenically milled then pressed into pellets. With this level of preparation no other (signal) processing was required despite differences in composition (sugar content, chocolate, different grains) |
Element | Detection Limit (ppm) | Wavelength (nm) | Other Wavelengths (nm) | Calibration Method | Calibration Range (ppm) | Notes |
---|---|---|---|---|---|---|
Ca | 9.5000 (Calibration Curve Slope) | 393.3000 | N/A | Univariate Calibration | 16.0000-3734.0000 | Analysis of cryogenically milled samples, pressed into pellets. LOD less than Ca content in any Breakfast Cereal tested. |
