1.PDA Stands for PHOTO DIODE ARRAY DETECTOR.
It is Used to take Multi wavelength chromatograms.
2.The purity of the peak is good or not will be known by
PDA.
3.For Example your sample has three componets. each
componenet has different wavelength maxima. in that case it
is not possible by UV in singl injection. we can do it by
PDA Detector only.
4.In case of UV, It is dual wavelength detector only.

We use Potassium Dichromate solution for the calibration of UV-Visible Spectrophotometer in UV region. My question is to calibrate visible region which solution could be used in photometric accuracy

when we talk about change in entropy we consider total entropy means of surround +entropy of system but when we talk about change in Gibss free energy we consider entropy of system.explain with reason.
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?
