- Reason why a reference material must be analysed side by side with the sample in in DSC analysis
Step by step

- One method for quantitative determination of the concentration of constituents in a sample analyzed by gas chromatography is the area normalization method. In this method, complete elution of all of the sample constituents is necessary. The area of each peak is then measured and corrected for differences in detector response to the different eluates. This correction is accomplished by dividing the area by an empirically determined correction factor. The concentration of the analyte is found from the ratio of its corrected area to the total corrected area of all peaks. For a chromatogram containing three peaks, the relative areas were found to be 16.4, 45.2, and 30.2 in the order of increasing retention time. Calculate the percentage of each compound if the relative detector responses were 0.60, 0.78, and 0.88, respectivelyWhat are method blanks and method detection limit used in analytical chemistry? Explain thoroughlyWhy is strict implementation of LQMS (Laboratory Quality Management System) or GLP is necessary ? What are the elements ?
- The response of the instrument must be lincar in the sample matrix. Systematic errors can occur due to sample or standard preparation. It consists of a series of standard analyte solutions separate from the unknown. A blank is used to correct the response from the instrument. Known quantities of a standard solution of the analyte are added to the unknown. It is the method of choice when the matrix of the sample may affect the signal. Matrix effects can cause the same analyte concentration in an unknown and standard to give different responses. It is used to measure the instrument response as a function of a known analyte concentration under a set of conditions.Plot a professional quality standard curve (absorbance vs. protein amount in µg) with an appropriate title and caption underneath the plot from the data give above.

- Please help with the Chemical shift Splitting pattern Integration HNMRThe concentration of hydronium ions and hydroxide ions can vary widely in a solution, easily from 1 M to 1 x 10-14 M. This variation is too wide to fit on an analog readout. In order to make this into a smaller scale suitable for an analog readout, the log to the base 10 was used so that the read out is focused on powers of 10. Note that the log [1] = 0, and the log of 1 x 10-14 = -14. It was then decided that the numbers should be positive so the sign was changed. The way to measure concentrations of both H+ and OH- was thus defined as -log. This was then referred to as p. Thus, pH = -log[H+], pOH = -log[OH-], and pK = -log[Keq]. You need to figure out how to do this mathematical manipulation on your calculator. The acid-base reaction in pure water is H2O + H2O ⇔ H3O+1 + OH-1 and it was found that in pure water under standard conditions the [H3O+1] = [OH-1] = 1 x 10-7 M Neutral pH is defined as having a [H+] or [H3O+1] of 1 x 10-7 M. The pH of a neutral solution is thus pH = -log[1 x…List three typical examples applications of SFC analysis.
