HPLC stands for High Performance Liquid Chromatography.
HPLC is a technique used to separate, identify, and quantify components in a mixture.
It involves the use of a liquid mobile phase and a stationary phase.
The mobile phase carries the sample through the stationary phase, where separation occurs based on different interactions.
HPLC is widely used in pharmaceutical, environmental, and forensic analysis.
It is used to an...
Utilities are services that provide essential facilities or resources for a community or organization.
Electricity: Provides power for lighting, heating, and operating electrical appliances.
Water: Supplies clean water for drinking, cooking, and sanitation purposes.
Gas: Used for cooking, heating, and powering certain appliances.
Telecommunications: Includes telephone, internet, and television services.

Distillation is a process of separating components of a mixture based on their boiling points.
It involves heating the mixture to vaporize the component with the lowest boiling point.
The vapor is then condensed and collected as a separate liquid.
Types of distillation include simple distillation, fractional distillation, and steam distillation.
Simple distillation is used for separating liquids with large differences in b...
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.
Catalysts lower the activation energy required for a reaction to occur.
They provide an alternative reaction pathway with a lower energy barrier.
Catalysts can be in the form of enzymes, metals, or other substances.
They are not consumed or permanently changed during the reaction.
Examples include platinum in cata...
pH is a measure of the acidity or alkalinity of a solution. It ranges from 0 to 14, with 7 being neutral.
pH stands for 'potential of hydrogen'
It measures the concentration of hydrogen ions in a solution
A pH value below 7 indicates acidity, while above 7 indicates alkalinity
Pure water has a pH of 7, which is considered neutral
Examples of pH values: lemon juice (pH 2), baking soda (pH 9), stomach acid (pH 1)
PH is a measure of acidity or basicity of a solution. It ranges from 1 to 14, with 7 being neutral.
PH = - log into base H+ ion concentration
Range of PH: 1 to 6.9 acidic, 6.9 to 7.1 neutral, 7.1 to 14 basic
Acidic solutions have a higher concentration of H+ ions, while basic solutions have a higher concentration of OH- ions
PH is important in many fields, including chemistry, biology, and environmental science
I applied via Referral and was interviewed before Feb 2021. There were 2 interview rounds.
Clean rooms are classified based on the level of cleanliness required for specific applications.
Clean rooms are classified into different classes based on the maximum allowable number of particles per cubic meter of air.
The classification system is defined by international standards such as ISO 14644-1.
Some common types of clean rooms include ISO Class 1, ISO Class 5, and ISO Class 8.
Clean rooms are used in various ind...
I applied via Company Website and was interviewed before Mar 2021. There were 3 interview rounds.
Chemistry is the scientific study of matter, its properties, and interactions with other matter and energy.
Chemistry is divided into five main branches: organic chemistry, inorganic chemistry, analytical chemistry, physical chemistry, and biochemistry.
PH is a measure of the acidity or basicity of a solution, with a range of 0-14. A pH of 7 is neutral, below 7 is acidic, and above 7 is basic.
Other important concepts in ...
