Atomic absorption of mercury

Hello!

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...

Federico
