Answer Posted / suresh darling
assay means the total amount of API present in that tablet.
as per usp 97 to 103, as per IP 95 TO 100.
formula: area of sapmle/area of standard* wt of sample/x *
y/ wt of stanadrd * purity/100 * a.wt/l.c *100.
uniformity of content means in that we have taken 10
samples at a time we check the API in that sample wether it
is uniform or not.
formula: area of sapmle/area of standard* wt of sample/x *
y/ wt of stanadrd * l.c/100.

how you start the solubility study?
If change in specification which parameter require to do for validation? if change in chromtographic condition then which parameter? if api change then which parameter? if change composition then which parameter? if old method not work out then whicj parameter? if additional one impurity added then which parameter of validation require to do on above each conditions? elaborate separately

calibrtion procedue of LC-MS
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?
