What is the difference between an instrument detection limit and a method detection limit?
Just so, what is instrument detection limit?
Instrument Detection Limit (IDL) is the concentration equivalent to a signal, due to the analyte of. interest, which is the smallest signal that can be distinguished from background noise by a particular. instrument.
Secondly, what is the difference between limit of detection and limit of quantification? LoD is the lowest analyte concentration likely to be reliably distinguished from the LoB and at which detection is feasible. LoQ is the lowest concentration at which the analyte can not only be reliably detected but at which some predefined goals for bias and imprecision are met.
Also question is, how do you calculate limit of detection?
Basically you make a solution of the analyte that is one to five times the estimated detection. Test this solution seven or more times, then determine the standard deviation of the data set. The method detection limit is calculated according to the formula: MDL = Student's t value x the standard deviation.
What is the difference between sensitivity and detection limit?
Detection limit, as they state very well in another part of the text, is the lowest detectable level of analyte distinguishable from zero, whereas analytical sensitivity is the slope of the calibration curve. The higher the analytical sensitivity, the lower the detection limit.
