why has inject 6 injection in Releted compounds..

Answer / ramakrishna- micro labs

In RS analysis we r analysed for impurity purpose,here we take
more concentration when compare to standard,that's why
standard area comes very less when compare to sample,so inject
standard 6 replicates the % RSD is NMT 5.0 , we give 5
replicates %RSD is NMT 2.0,the system suitability criteria
than more chances to pass for 6 replicates injections
