Schematic overview of the data acquisition system for broadband acoustic resonance dissolution spectroscopy (BARDS).
Source publication
Broadband acoustic resonance dissolution spectroscopy (BARDS) has been recently introduced as a low-cost method for the analysis of powdered materials. In this study, ten Iranian natural table salts, each separated into five particle size fractions, were analyzed with BARDS. The compositions and crystalline structure of samples were investigated wi...

Context 1
... broadband acoustic resonance dissolution spectrometer (BARDS Acoustic Science Labs, Cork, Ireland) was used to obtain the acoustic profiles of the salt samples (Fig. 2). This spectrometer has a dissolution vessel made of borosilicate, suitable for 25 mL solvent which was demineralized water in this study. The sound was generated by the means of a magnetic stirrer, rotating off-set at the speed of 300 rpm, exciting the vessel's wall. The acoustic sensor was a uni-directional, cardio design, condenser ...
Context 2
... salts (PBH_HQ, PBH_MQ, PBH_LQ, IBH, IPH_HQ, IPH_LQ, and IH) were very similar to each other (Fig. 3a). F ERP of the sea salts (USS, ArSS, and ArSS_R) was remarkably lower than those of the rock salts. The lower F ERP at the same particle size range represents the higher powder ability of bubble formation at the early stages of the dissolution (Fig. 2). The presence of MgCl 2 in the sea salts (Table 1) may be the cause of the lower frequency (higher bubble volume) at early seconds after the introduction of solute to the solvent. It has been stated that the causes of lower F ERP between two powders in the same particle size range are due to a higher total dissolution rate and higher ...
