What features of FTIR spectroscopy make it useful for applications in sorting plastic recycling? Are there any disadvantages? Briefly explain.

7 of 10 > Atomic absorption spectroscopy was used to determine the amount of aluminum in a sample of sunscreen. A blank solution was measured seven times to determine the detection and quantitation limits of the spectrometer. The blank readings were: 0.0073, 0.0082, 0.0110, 0.0101, 0.0102, 0.0098, and 0.0090 AU. Determine the signal at the detection limit and the signal at the limit of quantitation for this method. signal detection limit: signal limit of quantitation: hulu étv 14
