I wasn´t able to find a definition of the unit mAU in the literature that is available to me.
It seems to be the unit for detector signals of various detector types e.g. UV or FID.
Maybe someone can tell me something about this?

Thanks a lot.

mAU = one-thousandth of an absorbance unit; absorbance unit as from UV-visible spectroscopy.

It is the mass Absorbance Unit

Hello anonymus,
only one remark: FID is an ionisation detector and here is NO absobance but a ionisation, normally in pA (pico-ampere = 10 exp-12A) really small unit)
If You read mAU in an FID system, someone has made a joke...

If feeble memory serves, if you read a Agilent GC FID file (such as copied onto floppy disk) on an Agilent HPLC Chemstation computer, the scale WILL show mAU.

ChemStation A.08.03 display "counts" for a FID signal, even if the SW was installed for a HPLC (just tried! :-))

How you define artifact? What are the characteristics of an artifact peak?

I am under the understanding that mAU = milli Absorbance Unit as opposed to mass Absorbance Unit
