Stability study is a process of testing the shelf life of a product under various conditions to ensure its quality and safety.

• Stability study determines the shelf life of a product

• It helps in identifying the optimal storage conditions for a product

• It ensures the quality and safety of a product over time

• Stability studies are conducted on pharmaceuticals, cosmetics, and food products

• Examples of stability testing include accelerated stability testing and real-time stability test...read more

HPLC and UV are analytical techniques used in quality control. HPLC separates and quantifies components in a mixture, while UV measures the absorption of light by a sample.

• HPLC uses a stationary phase and a mobile phase to separate and quantify components in a mixture.

• Calibration of HPLC involves preparing standard solutions of known concentrations and plotting a calibration curve.

• UV measures the absorption of light by a sample at a specific wavelength.

• Calibration of UV invol...read more

Expected CTC, last CTC, and experience are important factors in determining fit for the role.

• Expected CTC: I am looking for a competitive salary based on my experience and skills.

• Last CTC: My last CTC was $X at my previous company.

• Experience: I have X years of experience in quality control roles.

I always maintain a record of my work and behavior to ensure accountability and improvement.

• I keep a log of my daily tasks and accomplishments

• I regularly seek feedback from my supervisor and colleagues

• I take responsibility for my mistakes and work to correct them

• I strive to maintain a positive and professional attitude at all times

HPLC stands for High Performance Liquid Chromatography, a technique used to separate, identify, and quantify components in a mixture.

• HPLC involves passing a liquid sample through a column filled with a stationary phase, where different components in the sample interact differently with the stationary phase and elute at different times.

• The eluted components are detected and quantified based on their retention times and peak areas.

• HPLC is commonly used in pharmaceutical, enviro...read more

Force is the external influence applied on an object, while strain is the deformation caused by the force.

• Force is a vector quantity, while strain is a scalar quantity.

• Force is measured in Newtons (N), while strain is measured in units of length per length (e.g. mm/mm).

• Force can cause different types of strain, such as tensile, compressive, or shear strain.

• Examples of force include gravity, friction, and tension, while examples of strain include stretching, bending, and twist...read more

pH is a measure of the acidity or alkalinity of a solution on a scale of 0 to 14.

• pH stands for 'potential of Hydrogen'

• It indicates the concentration of hydrogen ions in a solution

• A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline

• pH is important in various industries such as food, pharmaceuticals, and environmental monitoring

HPLC process is a chromatographic technique used to separate, identify, and quantify components in a mixture.

• HPLC stands for High Performance Liquid Chromatography.

• It involves passing a liquid sample through a column filled with a stationary phase, where different components interact differently and get separated.

• The separated components are detected and quantified based on their retention times.

• HPLC is commonly used in pharmaceutical, environmental, and food industries for q...read more

GC process stands for Gas Chromatography process used for separating and analyzing compounds in a mixture.

• GC process involves injecting a sample into a heated inlet, where it vaporizes.

• The vaporized sample is carried by an inert gas through a column packed with a stationary phase.

• Different compounds in the sample interact differently with the stationary phase, leading to separation based on their properties.

• The separated compounds are detected by a detector at the end of the ...read more
