Homework Help: Atomic absorption of mercury

  1. Jan 9, 2010 #1

    Mercury vapour detection is normally performed at 253.6 nm, which is the lowest emission line in the UVC range.
    I have to figure out if a similar atomic absorption approach would be valid at a longer wavelength, specifically at 365 nm, which is an other emission line but into the UVA range.
    I guess 253.6 nm was always used because it is the most abundant radiation emitted by simple discharge in a mercury vapour lamp, but would it also work ar 365 nm from a laser system?

    Thanks to anybody helping...
