Area classification refers to the classification of hazardous areas based on the presence of flammable gases, vapors, liquids, or combustible dusts.
Area classification is important for determining the type of electrical equipment that can be used in a specific area.
Common classifications include Class I (flammable gases or vapors), Class II (combustible dusts), and Class III (flammable fibers).
Examples of hazardous are...
I applied via Referral and was interviewed before Oct 2022. There were 3 interview rounds.
HPLC stands for High Performance Liquid Chromatography, a technique used to separate, identify, and quantify components in a mixture.
HPLC involves a stationary phase, mobile phase, and a detector.
It is commonly used in pharmaceutical, environmental, and food industries.
HPLC can separate complex mixtures into individual components for analysis.
It is a powerful tool for quality control and research purposes.

A clean area is a controlled environment that is free from contaminants and pollutants.
Clean areas are commonly found in industries such as pharmaceuticals, electronics, and food processing.
These areas are designed to minimize the presence of particles, dust, microbes, and other impurities.
Clean areas often have specialized ventilation systems, air filters, and strict protocols for cleanliness.
Examples of clean areas i...
Arch Pharmalabs interview questions for popular designations
I was interviewed in Sep 2016.
Pneumatic systems use compressed air to transmit power, while hydraulic systems use fluid to transmit power.
Pneumatic systems use air as the working fluid, while hydraulic systems use liquid.
Pneumatic systems are typically used for lighter loads and faster movements, while hydraulic systems are used for heavier loads and slower movements.
Pneumatic systems are generally less expensive and easier to maintain compared to ...
There are several types of welding techniques used in various industries.
Arc welding: Uses an electric arc to create heat and join metals.
MIG welding: Uses a consumable wire electrode and shielding gas to join metals.
TIG welding: Uses a non-consumable tungsten electrode and inert gas to join metals.
Spot welding: Joins metal sheets by applying pressure and heat at specific points.
Flux-cored arc welding: Similar to MIG w...
CNC and lathe machines are used for precision cutting and shaping of materials.
CNC machines use computer programming to control the cutting tools, allowing for highly precise and complex shapes to be created.
Lathe machines are used for turning and shaping cylindrical objects, such as metal rods or wooden dowels.
Both machines are commonly used in manufacturing and engineering industries.
Examples of products made using C...
UPLC stands for Ultra Performance Liquid Chromatography.
UPLC is a technique used in analytical chemistry to separate, identify, and quantify components in a mixture.
It is an advanced form of liquid chromatography that utilizes smaller particle sizes and higher pressures for faster and more efficient separations.
UPLC is commonly used in pharmaceutical, environmental, and food analysis.
It offers improved resolution, sens...
