13) Explain what makes a molecule into organic molecule?
In a molecule when a hydrogen atom is less than the ratio of the carbon atom, then such molecules are referred to as an organic molecule.
What is your opinion on the role of computers in analytical chemistry?
There are many ways in which computers can be used in analytical chemistry, from simple data processing and analysis to more complex applications such as mathematical modeling and simulation. The interviewer is likely interested in the candidates opinion on the usefulness of computers in analytical chemistry, and how they believe they can help or hinder the work of an analytical chemist. It is important for the interviewer to understand the candidates views on this topic so that they can gauge their level of expertise and understanding of the subject matter.
Example: “ I believe that computers play a very important role in analytical chemistry. They help us to store and organize data, as well as to perform complex calculations. Additionally, computers can be used to create models of chemical systems, which can be used to predict the behavior of real-world systems. ”
How do you see the future of analytical chemistry?
The interviewer is asking how the analytical chemist sees the future of analytical chemistry because it is important to know how the field is progressing and what new technologies or methods may be developed. This information can help the company plan for the future and make sure that they are using the most up-to-date methods.
Example: “ The future of analytical chemistry is very exciting. With the advent of new technologies, analytical chemists will be able to develop more sensitive and specific methods for analyzing chemicals. Additionally, analytical chemistry will become increasingly important in the field of nanotechnology as researchers strive to develop ever-smaller devices. ”
What is your experience with method validation?
An interviewer might ask “What is your experience with method validation?” to an Analytical Chemist in order to gauge the Chemists experience and expertise in the field. Method validation is an important process in analytical chemistry that ensures the accuracy and precision of analytical methods.
Example: “ I have experience with method validation in the context of analytical chemistry methods. This includes validating new methods, as well as verifying the performance of existing methods. In general, method validation involves assessing the suitability of a given method for a specific purpose, and ensuring that the results obtained from the method are accurate and precise. This usually requires designing and conducting experiments to test the various aspects of the methods performance. ”
tlc is used to check wheather the reaction is completed or not. hplc is used to identify, quantify,and for separation of mixture
calibration is also one of the system suitability test,whether the system working satisfactory or not physically so when you do the calibration for pH meter with standard pH buffer solution (which is from NIST-it may accurate solution for actual pH)and once if your instrument has calibrated,you can cross verify your insrument against those pH buffer solution (NIST) and the acceptable range is +/- 0.02 then you can conclude for ? once if temperature raises the pH will decrease and its not all cases
#Base line is nothing but the detectors response to the mobile phase.(gc,hplc) #Base line should be stable to start a run. #Un stabilized base line is called as base line noise. #Base line noise is of many types.. 1)Cyclic base line 2)Synchorinise noise 3)Asynchorinise noise 4)Base line drift 5)Spikes 6)Negative peaks 7)No peaks #Base line noise is attributed due to mobile phase,sample, system problems.leaks in the system,temperature variations in lab etc..
The chemical substances that pair each other, to form complexes. These can use for stabilization of one of the molecule that is more active or to colorifying etc.
The H is the height of the main peak and the h is the lowest height of a peak in the range of X5 the main peak (around the amin peak)
