What is Resolution?

-

The resolution is the separation of two components in a mixture, calculated by:

Resolution = 2 × (tR2 − tR1)/(W1 + W2) 

where tR2 and tR1 are the retention times of the two components; and W2 and W1 are the corresponding widths at the bases of the peaks obtained by extrapolating the relatively straight sides of the peaks to the baseline. 

Where electronic integrators are used, it may be convenient to determine  the resolution, by the equation: 

Resolution = 1.18 × (tR2 − tR1)/(W1,h/2 + W2,h/2)

What relation Resolution and Peak seperations?

What is Retention time?

Retention time (RT) is a measure of the time taken for a solute to pass through a chromatography column. Retention time (RT) is calculated as the time from injection to detection. The RT for a compound is not fixed as many factors can influence it even if the same instrument and column are used.  These include: The flow rate Temperature differences in the oven and column Column degradation Column length What is RRT?

What is RRT?

Relative retention time (RRT) is the ratio of the retention time of analyte peak relative to that of another used as a reference obtained under identical conditions. RRT = (T analyte / T reference)  Wher T = Retention time As per USP Relative retention time (RRT): Also known as the “unadjusted relative retention”. Comparisons in USP–NF are normally made in terms of unadjusted relative retention, unless otherwise indicated. RRT = tR2/tR1 The symbol rG is also used to designate unadjusted relative retention values. The use of the relative retention time (RRT) reduces the effects of some of the variables that can affect the retention time. What is Retention time?

Establishment of expiry dating for chemicals, reagents, solutions, and solvents?

Laboratory “reagents, and standard solutions,” as referenced in the CGMP regulations at 211.194, includes laboratory chemicals such as solvents (including mobile phases), dry chemicals (salts, primary standards, etc.), and solutions (buffers, acids/bases, quantitative analytical preparations, etc.), whether purchased or prepared in-house. Laboratory reagents and solutions are used in analytical tests of components, in-process materials, and finished products. If the purchased laboratory reagent or solution includes a manufacturer’s suggested "use by" or expiry date, that date should be followed. For purchased laboratory reagents and solutions without a "use by" or expiry date, FDA would expect that an assessment be conducted (literature review may be acceptable) of that specific chemical's or chemical family's stability and that an appropriate "use by" or expiry date be determined. For in-house prepared solutions, such as mobi
