10+ TCS Interview Questions and Answers

Incidence OOS and OOT refer to out-of-specification and out-of-trend occurrences in research and scientific analysis.

• Incidence OOS (Out-of-Specification) refers to test results that fall outside the predetermined acceptance criteria or specifications.

• Incidence OOT (Out-of-Trend) refers to a trend in data that deviates from the expected or established pattern.

• Both incidences are important in research and scientific analysis as they indicate potential issues with the quality, r...read more

GLP, GDP, GMP, and data integrity are important concepts in scientific research and quality control.

• GLP stands for Good Laboratory Practice and refers to a set of guidelines for conducting non-clinical laboratory studies.

• GDP stands for Good Documentation Practice and involves maintaining accurate and complete records of all activities and data.

• GMP stands for Good Manufacturing Practice and ensures that pharmaceutical products are consistently produced and controlled according...read more

Molarity, normality, and molality are units of concentration used in chemistry.

• Molarity is the number of moles of solute per liter of solution.

• Normality is the number of equivalents of solute per liter of solution.

• Molality is the number of moles of solute per kilogram of solvent.

• Molarity and normality are temperature-dependent, while molality is not.

• Example: A solution with a molarity of 0.5 M contains 0.5 moles of solute per liter of solution.

HPLC principle is a chromatographic technique used to separate, identify, and quantify components in a mixture based on their interaction with a stationary phase and a mobile phase.

• HPLC stands for High-Performance Liquid Chromatography.

• It involves the use of a stationary phase (typically a solid or liquid) and a mobile phase (liquid) to separate and analyze components in a sample.

• The separation is based on the differential interaction of the components with the stationary pha...read more

Data integrity refers to the accuracy, consistency, and reliability of data throughout its lifecycle. Alcoa principles emphasize ensuring data integrity in pharmaceutical manufacturing.

• Data integrity ensures that data is accurate, consistent, and reliable.

• Alcoa principles (Attributable, Legible, Contemporaneous, Original, Accurate) are used to ensure data integrity in pharmaceutical manufacturing.

• Examples of maintaining data integrity include proper documentation, regular aud...read more

UV principle refers to the principle of ultraviolet radiation and its effects on various materials and organisms.

• UV principle is based on the understanding of ultraviolet radiation, which is a type of electromagnetic radiation with a wavelength shorter than that of visible light.

• Ultraviolet radiation can have both beneficial and harmful effects on different materials and organisms.

• UV principle is widely used in various fields such as physics, chemistry, biology, and environme...read more

The marks of each subject in 10th standard vary depending on the specific subjects taken by the student.

• Subjects like Mathematics, Science, English, Social Studies, and a second language are common in 10th standard

• Each subject is typically graded out of 100 marks

• Grades are usually given in the form of percentages or CGPA

Cream is a dairy product composed of the higher-butterfat layer skimmed from the top of milk before homogenization.

• Cream is made by skimming the top layer of milk, which contains a higher concentration of butterfat.

• The cream is then pasteurized to kill any harmful bacteria.

• Different types of cream include heavy cream, light cream, and whipping cream.

• Cream is commonly used in cooking and baking to add richness and flavor to dishes.

Primary packing is the initial packaging of a product, while secondary packing is the packaging used to group and protect primary packs.

• Primary packing is the first layer of packaging that directly touches the product.

• Secondary packing is used to group and protect primary packs for transportation and display.

• Primary packing is usually in direct contact with the product, while secondary packing is more for marketing and logistics purposes.

• Examples: Primary packing can be a bli...read more

Forced degradation studies involve subjecting a drug substance or product to stress conditions to determine its stability.

• Forced degradation studies are conducted to evaluate the stability of a drug substance or product under various stress conditions such as heat, light, humidity, and oxidation.

• The purpose of these studies is to identify potential degradation products and degradation pathways of the drug.

• Various analytical techniques such as HPLC, GC-MS, and NMR are used to ...read more
