Common Questions Asked in Interview for the post of Synthesis Chemist | Analytical Chemist | Quality Control Chemist

-

Question 1) What is Good manufacturing practices (GMP)?
Answer: 
Good manufacturing practices are regulation, codes, and guidelines for the manufacture of drug products, medical devices, in vitro and in vitro diagnostic products, foods. The term “cGMP” is used by the federal government as a current good manufacturing practice.

Question 2) What is GLP?
Answer: 
GLP stands for Good Laboratory Practice. It is a quality control system used in research laboratories to ensure data integrity( i.e. data is generated under high quality and reproducible conditions). enable mutual acceptance of data between countries.

Question 3) What are the Rules of lab safety?
Answer: 
Rule 1:WALK
When going into the lab make sure to WALK. there will be no running in the lab. There will be materials and equipment out that can break if you accidentally knock into them. There may be electrical wires on the ground that you may trip over as well. DO NOT RUSH. Walk slowly and be careful. 

Rule 2: PROPER LAB ATTIRE
You have been given a schedule of when our labs will be held. The day before we do a lab will remind you so that you can come to class prepared with proper lab attire. 

Proper attire is as follows:

  1. CLOSED TOED SHOES
  2. HAIR MUST BE TIED BACK
  3. SAFETY GOGGLES 
  4. LAB COATS 

Rule 3: HANDLING CHEMICALS
When handling chemicals during lab it is important to proceed with caution. Wear gloves whenever pouring chemicals or handling them. If there is a spill be sure to let the teacher know. If you have to dispose of chemicals, always use the waste containers provided on your lab tables. NEVER POUR THE CHEMICALS BACK INTO THE CONTAINER YOU GOT IT FROM. If you do, whatever was in your container could cause a chemical reaction with the chemical in the original container.

NEVER SMELL A CHEMICAL DIRECTLY. You can fan the fumes toward yourself. You can do this by waving your hands over the flask or beaker (I will demonstrate).

Rule 4: HANDLING EQUIPMENT

It is important that when you are using different lab equipment, you handle them with care. The microscope should be held with both hands, one underneath, and one on the arm. When handling glassware be sure to hold it with both hands when can. If something is hot, then make sure to use a pair of tongs. NEVER USE YOUR HANDS.

Rule 5: HAND WASHING

BEFORE LEAVING THE LAB ALWAYS WASH YOUR HANDS. Make sure you use soap and water and rub your hands thoroughly at the handwashing station. Some of the materials we will be using could be harmful to you, so you must wash your hands so you do not get sick.   

Question 4) What is the main purpose of the chemistry laboratory?
Answer: 
The purpose of the laboratory component of the course is several-fold. It reinforces the material you have learned in a class and it gives a chance to apply your knowledge. You will learn some important experimental techniques that are necessary for you to become an effective chemist.

Question 5) What is meant by QMS?
Answer: 
A quality management system (QMS) is defined as a formalized system that documents processes, procedures, and responsibilities for achieving quality policies and objectives.

Question 6) What is the difference between QA and QC?
Answer: 
QA is a set of activities for ensuring quality in the processes by which products are developed. QC is a set of activities for ensuring the quality of products. The activities focus on identifying defects in the actual products produced. QA aims to prevent defects with a focus on the process used to make the product.

Question 7) How do you behave in a lab?
Answer: 
Dress for lab work. Roll up your sleeves and keep long hair tied back. Wear shoes that are closed-toe, low heeled, and cover your entire foot. Wear clothes that cover your whole body, such as long pants or long skirts. jewelry and contacts should not be worn in the lab.

Question 8) What is SOP?
Answer: 
A standard operating procedure (SOP) is a set of step by step instructions compiled by an organization to help workers carry out complex routine operations. SOPs aim to achieve efficiency, quality output, and uniformity.of performance while reducing miscommunication and failure to comply with industry regulation.

Phosphating processes

Phosphating processes: According to heading fall such processes as result in formation of an insoluble phosphate coating on the surface of a metal. The formation of such coatings is invariably linked with the corrosion of the substrate metal. In a narrower definition, phosphating processes are only those which form surface coatings with useful properties. Thus phosphoric acid pickling solutions are a marginal case, since their primary function is removal of corrosion products and their usefulness in forming protective phosphate coating is very much a secon dary one. Technically and economically, the most important processes are those based on aqueous solutions which form protective coatings on metal surfaces, whether by spraying, pouring, immersion or other methods. Depending as to whether or not components are coated on removal from the solution, one may distinguish between the so-called phosphate coating processes and the 'non-coating" alternatives. In addition, there are ph

Organic Nanochemistry

Organic Nano chemistry:  Organic Nano chemistry is a branch of chemistry that studies organic reactions involving chemical synthesis of drugs, polymers and natural products which also includes the study of individual organic molecules in the laboratory. Nano materials: Nano materials are single unit sized , which can be described by the principle of 1 to100 nm of Nano scale or 1 to 10-9 meters. When scientists observed the different variations in materials he gave the Nano as a prefix to the Nano chemistry. Several chemical modifications on nanometer scale structure, approves effects of being size dependent. Nanoscale material: Nanoscale materials are also known as nanoscopic scale, which is lower bound to the mesoscopic scale for most solids. These usually refer to structures with a length scale applicable to nanotechnology, these materials where at least one relevant length scale, within the range of nanometers ranges from 1-100 nanometers.  These materials usually have v

Carbon: An important element

-

Allotropy -  some elements occur in nature more than one form. The chemical properties of these different forms are the same but their physical properties are different. This property of the elements is called allotropy.  Allotropes of carbon : The element carbon is available abundantly in nature and occurs in free as well as in a combined state.  1. Symbol of carbon-C 2. Atomic number -6 3. Atomic mass -12 4. Electron configuration- 2,4 5. Valency -4 6. Non-metallic element Compounds obtained directly or indirectly from plants and animals are called organic compounds and compounds obtained from minerals are called inorgani uuc compounds. All the organic compounds contain carbon. Carbon is the main element even in cellular DNA and RNA that transfer hidden characteristics from one generation to the next. Occurrence of carbon - The name carbon is derived from the Latin word 'carbo' meaning coal. Carbon is found in nature in a free as well as compound state carbon in t
