In dissolution of tablets/capsules elaborate the Dissolution limit 20.0% to 60% Q in 30 minutes.
1 2832what is the limit for KF Factor ,we take factor using water we will found factor between 6 to 7 ,while on KF Reagent bottle mentioned 5 mg/ml water content.if we not use dried methanol it is effect on factor.
Atul,
1 2813Why only hydroxy naphthol blue indicator is used for standardisation of 0.05M EDTA solution instead of solochrome Black T or Euriochrome Black T indicator which is used for all sample analysis with 0.05M EDTA solution?

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
