| A key historic (1973) paper for rare earth detection limits. As the detection used photographic film, there is no detector gating. Samples were prepared from various stock solutions, then evaporated and powdered. Finally the powder was pressed into pellets for analysis. It was found that the sample matrix (Sodium Chloride, Sodium Nitrate, Sodium Perchlorate, Sodium Sulfate, Sodium DiHydrogen Phosphate) had an effect on the spectra. Sodium Sulfate had a particularly strong dampening effect on the spectra, but most matrices gave weaker signal than Sodium Chloride. | |||||
