- Q1. What is the role of pka in HPLC method development
- Ans.
pKa plays a crucial role in HPLC method development by determining the ionization state of analytes and their retention on the stationary phase.
pKa helps in selecting the appropriate mobile phase pH for ionizable compounds.
It influences the ionization of analytes, affecting their solubility and interaction with the stationary phase.
pKa values aid in optimizing separation by adjusting the pH to enhance selectivity and r...
- Q2. How pka value of the product is calculated
- Ans.
The pKa value of a product is calculated based on its acid dissociation constant and the concentration of the acid and its conjugate base.
pKa is a measure of the acidity or basicity of a compound.
It is calculated using the equation: pKa = -log10(Ka), where Ka is the acid dissociation constant.
The acid dissociation constant is the ratio of the concentration of the dissociated form of the acid to the concentration of the...
- Q3. Tyes of titration with mechanism
- Ans.
Titration is a technique used in chemistry to determine the concentration of a substance in a solution.
Acid-base titration: involves the reaction between an acid and a base to determine the concentration of either
Redox titration: involves the transfer of electrons between reactants to determine the concentration of a substance
Complexometric titration: involves the formation of a complex between a metal ion and a ligand...
- Q4. How to develope a HPLC Related substances method
- Ans.
Developing an HPLC related substances method involves selecting appropriate column, mobile phase, and detection wavelength.
Select a suitable column based on the analyte properties and separation requirements.
Optimize the mobile phase composition and gradient program for efficient separation.
Choose an appropriate detection wavelength based on the analyte's UV absorption properties.
Validate the method by testing specific...
- Q5. How many types of GC Capillary column and which one is best& why
- Ans.
There are several types of GC capillary columns, including non-polar, polar, and specialty columns. The best type depends on the specific application and analytes being analyzed.
Non-polar columns are best for separating non-polar compounds, such as hydrocarbons.
Polar columns are ideal for separating polar compounds, such as alcohols and acids.
Specialty columns, like chiral columns, are used for separating enantiomers.

- Q1. 1) self introduction 2) How to develop method for Api to finished products of Assay and Related substances in injectable? 3) column chemistry? 4) method validation 5) ich guidelines
- Ans.
The interview questions cover topics such as self-introduction, developing methods for API to finished products, column chemistry, method validation, and ICH guidelines.
For self-introduction, briefly talk about your background, education, and relevant experience.
To develop a method for API to finished products, consider factors such as the desired assay and related substances, analytical techniques, and regulatory requ...
- Q2. 6)if mass balance not achieved in forced degradation then whts the possible reason??
- Ans.
Possible reasons for not achieving mass balance in forced degradation
Incomplete degradation of the analyte
Formation of unknown degradation products
Loss of analyte during sample preparation or analysis
Inaccurate measurement of sample or standard volumes
Errors in weighing or dilution of samples
Contamination of samples or equipment
Inadequate mixing or homogenization of samples
Inefficient extraction of analyte from the mat...
- Q3. 7) how to develop multimedia dissolution method?
- Ans.
Multimedia dissolution method can be developed by considering the physicochemical properties of the drug and the media used.
Select appropriate media that mimic the physiological conditions of the drug's intended site of action
Determine the solubility and stability of the drug in different media
Optimize the pH and temperature of the media to enhance drug solubility
Use appropriate equipment and techniques for sample prep...
- Q4. 8) what is sink condition in dissolution?
- Ans.
Sink condition in dissolution refers to a state where the drug being dissolved is completely solubilized and no further dissolution occurs.
Sink condition is achieved when the concentration of the drug in the dissolution medium is much lower than its solubility.
It ensures that the dissolution process is not limited by the drug's solubility but by other factors like diffusion.
Sink condition is important for accurate and ...
- Q5. 9) pka value determination and their role in development?
- Ans.
pKa value determination and their role in development
pKa value is a measure of the acidity or basicity of a compound
It helps in understanding the chemical properties and behavior of a compound
pKa values are important in drug development as they affect drug solubility, absorption, and stability
Determining pKa values can aid in optimizing drug formulations and predicting drug-drug interactions
- Q6. 10) Bsc classification and their uses.
- Ans.
Bsc classification is a system used to categorize and classify living organisms based on their characteristics.
Bsc classification stands for Biological Species Concept classification.
It is used to group organisms based on their physical and genetic characteristics.
The classification system includes Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Each level of classification is based on specific characteristic...

- Q1. Difference between Tuple and Dictionary
- Ans.
Tuple is an ordered collection of elements, while a dictionary is an unordered collection of key-value pairs.
Tuples are immutable, while dictionaries are mutable.
Tuples are accessed using indexing, while dictionaries are accessed using keys.
Tuples are typically used to store related pieces of data, while dictionaries are used for mapping and lookups.
- Q2. What is Adjusted R square
- Ans.
Adjusted R square is a statistical measure that represents the proportion of variance in the dependent variable accounted for by the independent variables.
Adjusted R square is an extension of R square, which measures the goodness of fit of a regression model.
It takes into account the number of predictors in the model and adjusts for the degrees of freedom.
Adjusted R square ranges from 0 to 1, where a higher value indic...
- Q3. Which is better Random forest or XG Boost
- Ans.
Both Random Forest and XG Boost are powerful machine learning algorithms, but their performance depends on the specific problem and data.
Random Forest is an ensemble learning method that combines multiple decision trees to make predictions.
It is known for its ability to handle high-dimensional data and maintain good performance even with noisy or missing data.
XG Boost, on the other hand, is a gradient boosting algorith...
- Q4. What is Max pooling
- Ans.
Max pooling is a pooling operation that selects the maximum value from a region of the input data.
Max pooling is commonly used in convolutional neural networks (CNNs) for feature extraction.
It reduces the spatial dimensions of the input data while retaining the most important features.
Max pooling helps in achieving translation invariance, making the model more robust to variations in input position.
For example, in a 2x...
