Dishman Carbogen Amcis Research Associate Interview Questions and Answers

Q1. What is peak purity & % area normalisation??
Ans. 
Peak purity is the measure of the homogeneity of a peak in a chromatogram, while % area normalization is a method to compare the relative amounts of different peaks in a chromatogram.
• Peak purity is determined by comparing the spectra at different points within a peak to ensure they are similar, indicating a pure compound.

• % area normalization involves adjusting the peak areas in a chromatogram to a common reference poin...read more

Q2. What's difference between PDA & DAD detector??
Ans. 
PDA detector measures absorbance at multiple wavelengths, while DAD detector measures absorbance at all wavelengths simultaneously.
• PDA detector uses a photodiode array to measure absorbance at multiple wavelengths, allowing for more detailed analysis.

• DAD detector uses a diode array to measure absorbance at all wavelengths simultaneously, providing faster and more comprehensive data.

• PDA detector is more suitable for app...read more

Q3. What's Beer's Ambert Law??where it's applicable??
Ans. 
Beer's Ambert Law states that the absorbance of a substance is directly proportional to its concentration and the path length of the light through the sample.
• Beer's Ambert Law is commonly used in spectrophotometry to determine the concentration of a substance in a solution.

• The law is expressed as A = εlc, where A is the absorbance, ε is the molar absorptivity, l is the path length, and c is the concentration.

• It is appl...read more
