1 2436What is use of LOD and LOQ in validtion and give range and in calculation why we use 3.3* LOD here why we use 3.3
2 5546In the method validation proceedure,lod & loq calculation we use the formulae for LOD=3.3*SD/slope and for LOQ=10*SD/slope,why we use 3.3 & 10 in the formulae?
1 10077In HPLC Chromatographic separation Resolution equation is Rs = 1.18 (tR2 –tR1)/wh1+Wh2, Where, tR2 and tR1 is run time of eluent ratios of the distances from the point of application to the centers of the spots and the distance travelled by the solvent front from the point of application (retardation factor), and Wh1and Wh2 , is peak width of at half height. What is 1.18 ?
