why we are using 6 dosage units in dissolution, and why we
are using 6 tablets in disintegation test.is there any
scientific reason beyond 6?




Answer Posted / madan joshi

The use of six dosage units as the basic sample size in
dissolution is partially due to the configuration of the
dissolution test assembly with six positions. However, in
some statistical procedures such as the estimation of a
confidence interval for precision of a measurement, a
sample size of six represents the point of diminishing
returns where the decrease in the confidence interval from
5 units is significantly greater than the decrease from 6
to 7 units. Thus the added value of obtaining additional
measurements is significantly less once six measurements
have been acquired.

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
