Question: Which of the three options is the best approach to analyze tap water for minute levels of lead (expected levels <0.01 ppb).

Option 1: The water sample is filtered through a 0.45 um filter and then analyzed by Ion Chromatoraphy along with lead calibration standards for comparison

Option 2: The water sample is put into a Nebulizer attached to an ICP Spectrometer and the absorbance peak measured at the proper wavelength of lead. Standards are also analyzed to produce a calibration curve for comparison.

Option 3: The water sample is put into a Nebulizer attached to an ICP-MS instruent and the mass spectral data is used to determine the concentration of lead, compared to a calibration set of standards.
