How to Calibrate the Uncoded Hollow Cathode Lamps for 240 FS Atomic Absorption Spectrometer

To HJH: Yes, I agreed with your Lab manager -> It is NOT necessary to buy Coded (Certified) Hollow Cathode Lamps for your 220 FS AAS, however, he might neglect to give you some basic explanations.For Varia** AAS, I am NOT a Technical Expert, but according my 3-years experiences of Varia*: Coded Hollow Cathode Lamps is only good for the automatic lamp recognition SpectrAA software. So I prefer the Lower priced uncoded Hollow Cathode Lamps.

But, always remember that you need to Calibrate the Uncoded Hollow Cathode Lamps before the 1st analysis. 1-3 step is OK.
