Chrome Azurol S (CAS) has been used as a chromogenic reagent in the design of specific reagent strips for the determination by photothermal spectrometry (PTS) of beryllium(II) in aqueous samples collected on a membrane filter. This reagent must be carefully formulated for compatibility, stability, reaction speed, sensitivity and freedom from interferences. A linear relationship existed between PTS signal amplitude and Be(II) concentration for the concentration range of 0.1-15 μg g-1. The potential of this method for long-term sample storage is important in practical applications where the samples cannot be analyzed for Be(II) immediately after their collection on membrane filters in the field.
