how to calculate ppm of quinine in the sample

Using the same 1000 item sample, the standard deviation is calculated to be. Next, determine the standard deviation of the sample. In this case, after 1000 items are produced the mean is found to be 4.75 inches. Quinine hemisulfate salt monohydrate: C20H24N2O20.5H2SO4H2O, Molecular Weight: 391. Process results: calculate amount of quinine in your starting sample in mg/mL. Analyze your results using the calibration. Quinine: C20H24N2O2, Molecular Weight: 324.44 g/mol. Dilute the sample using 100 mL volumetric flasks, and measure the intensity at emission maximum in triplicate. This will be the mean of the dimension through a certain lot of goods. I need to turn it into the concentration of quinine (ppm) in the sample, then calculate the concentration of quinine (ppm) in tonic water. The upper limit of one of the dimensions on that product is 5 inches and the lower limit is 4 inches. When the FIA method was used, recoveries averaged 99.70 from mineral water samples spiked with 16.22 and 162.20 ppm quinine. In this example, we are looking at a product that needs to be made to certain specifications. The first step in calculating CPK (process capability index) is determining the upper and lower limits of the specifications. Where CPK is the process capability indexĬPK is defined as the process capability index and is a measure of the ability of a process to produce objects to a customer’s specifications.The following formula is used to calculate the CPK, or process capability index, of a given set of data.ĬPK = Min The CPK calculator will evaluate and display the process capability index of those values.

Enter the upper specification limit, lower specification limit, standard deviation, and process mean into the calculator.
