And what is limit of LOD and LOQ according to S/N ratio.

[@bachelorcookings1466]

LOD not lessthan 3
LOQ not less than 10

[@dhanajighadage6240]

Tnanks sir

[@gopalgirase-01]

But sir why we need to calculate S/N ratio?

[@diego39500]

It iss needed in order to calculate the LOD and LOQ. Also its good to understand how the system is performing with certain compounds.

[@diego39500]

@@gopalgirase-01 lod is limit.of detection, how low can your system detect there is something. And Loq is the limit of quatitation. Lod might be 3 times the SD of spike blanks. And loq is 3.3 times the lod
