Most substances are easily soluble in these solvents. They have lower absorbance in routine HPLC working range (205-400 nm). Hence no interference will be there due to these solvents.
Due to less density, they create less pressure in column and hence the column life can be improved.

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?
