minimum conc of the std compound in which the peak of the std get merged with noise called the LOD while LOQ is the 10 times multiple of LOD
The previously recorded answer in inaccurate on several levels (see below for quotations of previous repsonse)Linearity is the correlation of a regression line. Range is typically derived from linearity. Range implies that the method developed corresponds to the "range"between 80-120% (ideally) of the expected sample range (concentration, wt. etc). For content uniformity, range is expected to be 70-130% of the test concentration. These are guidelines governed by ICH Q2 R1 (International Conference for Hamonisation).In terms of HPLC method development:LOQ is the smallest amount that will give a S/N ratio of 10 meaning this is the smallest amount you may give a numerical value with confidence. TYPICALLY, THE LOWER RANGE (AND USUALLY LINEARITY) IS LOQ.LOD is the smallest value that will give an S/N ratio of 3, meaning you can say the specific compound is there qualitatively, but not quantitate the compound.Previous:"The range is any value that lies between the limit of detection (LoD) and the limit of quantitation (LoQ). Where the LoD is the lowest concentration that can be accurately measured and the LoQ is the highest concentration that can be accurately measured.Linearity describes the correlation to a regression line that has been fit to the data that. For some nice pictures to explain this see regression line at:"
Difference between collenchyma and chlorenchyma
Concentration of sample= estimated LOQ concentration (µg/mL) x 1/desired LOQ (%) x 100LOQ should be Equal to or less than 0.05% of that of test concentration. Response of the impurity should be NLT 2000 at LOQ level for better precision.
Potential difference.
Whichever is higher in value should be subtracted
LOQ (Limit of Quantification) is the lowest concentration of an analyte that can be reliably measured and quantified. LOD (Limit of Detection) is the lowest concentration of an analyte that can be distinguished from background noise but may not be reliably quantified. Both are important parameters in analytical chemistry to determine the sensitivity of an analytical method.
The Limit of Detection (LOD) and Limit of Quantitation (LOQ) can be calculated using the signal-to-noise ratio method. For example, LOD is typically calculated as 3 x standard deviation of the blank signal divided by the slope of the calibration curve. LOQ is typically calculated as 10 x standard deviation of the blank signal divided by the slope of the calibration curve. Both LOD and LOQ are important parameters to determine the sensitivity and reliability of an HPLC method.

'Actually for LOQ precision there is no guidelines, but LOQ definition is to be actually quantified with accuracy and precision. That,s why to conform the precision we are injecting six times and find the rsd less than 10%. It shows that LOQ is able to quantify with accuracy and precision
MC gives only % of water in a substance(Low melting range substance).But LOD result is a combination of water content and other volatile organic solvents.And more over Melting range of a substance has to be considered in case of LOD. Substances whichever is having high melting point is required for LOD checking.
