When recording an IR spectrum in the lab, we take no special precautions to account for the presence of oxygen, nitrogen, or argon in the air. What are the consequences of this?

Argon gas consists of individual atoms which can not undergo molecular vibration .So argon is IR inactive.oxygen & Nitrogen is having dipole moment zero during vibration.so Oxygen&Nitrogen is IR inactive.hence it is not necessary to consider this gases during IR analysis.

I have compare C2H2-air and C2H2-N2O flame AAS on determination calcium. Both use same range of std to plot calibration curve. (2-6ppm) When i measure the sample with phosphate, KCl and LaCl, C2H2-N2O flame give false positive result, around 0.5ppm. When i measure the sample with phosphste, KCl and EDTA. C2H2-N2O flame also give 0.5ppm false positive. But both above mentioned sample would not give false positive when measured by C2H2-air flame. What is the reason?

My question about gas chromatography sulfur chemiluminsecence detector. I test unknown sample gas by GC-SCD (calibrated ) and the result of *H2S is 279 PPM , *but when I test the same sample with the GC-TCD (calibrated ) the value of *H2S is 2500 PPM . I'd like to inform you that both GCs are calibrated and have very good operation conditions with stable parameters . the question is if the sample gas with higher H2S over detection limits of SCD detector (1000 ppm). why the result it 279 ppm Best regards
