GMP stands for Good Manufacturing Practices while cGMP stands for Current Good Manufacturing Practices.

• GMP is a set of guidelines for ensuring that products are consistently produced and controlled according to quality standards.

• cGMP is an updated version of GMP that includes current technologies and processes.

• cGMP is mandatory for pharmaceutical and biotech industries while GMP is not.

• cGMP requires documentation and validation of processes while GMP does not.

• Examples of cGMP...read more

pH is a measure of acidity or alkalinity in a solution. Sterilization is the process of killing or removing all microorganisms. Conductivity is the ability of a substance to conduct electricity. Sterilization temperature refers to the temperature required to kill microorganisms. Types of pH include acidic, alkaline, and neutral.

• pH is a numeric scale used to specify the acidity or alkalinity of a solution.

• Sterilization is the process of eliminating all forms of life, including...read more

Tablets are solid dosage forms of medication that are made by compressing a mixture of active ingredients and excipients.

• Tablets are a common form of medication that are easy to administer and store.

• They are made by compressing a mixture of active pharmaceutical ingredients (APIs) and excipients.

• The process of tablet manufacturing involves blending the ingredients, compressing them into a solid form, and coating if necessary.

• Common defects in tablet manufacturing include capp...read more

High Performance Liquid Chromatography (HPLC) system is used.

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

• Common types of HPLC systems include reverse-phase, normal-phase, and ion-exchange.

• Examples of HPLC systems include Agilent, Waters, and Shimadzu.

Grade of concrete refers to the strength of the concrete mix design.

• Grade of concrete is denoted by the ratio of cement to sand to aggregate in the mix.

• Common grades of concrete include M10, M15, M20, etc.

• Higher grade numbers indicate higher strength concrete.

• For example, M20 concrete has a compressive strength of 20 megapascals.

Downstream process refers to the steps involved in the purification and processing of a product after it has been produced.

• Involves purification and processing of a product

• Includes steps such as filtration, chromatography, and drying

• Goal is to isolate and purify the desired product

• Important in industries like pharmaceuticals, biotechnology, and food processing

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

• HPLC stands for High Performance Liquid Chromatography

• It involves passing a liquid sample through a column packed with a stationary phase material

• Different components in the sample interact differently with the stationary phase, leading to separation

• The separated components are detected and quantified as they elu...read more

The type of columns in HPLC are typically packed with stationary phase material to separate compounds based on their interactions with the stationary phase and mobile phase.

• Columns in HPLC can be classified based on the type of stationary phase material used, such as reversed-phase, normal-phase, ion-exchange, size-exclusion, and affinity columns.

• Reversed-phase columns are the most commonly used in HPLC, where the stationary phase is non-polar and the mobile phase is polar.

• No...read more

Cell theory is a fundamental principle in biology stating that all living organisms are composed of cells, the basic unit of life.

• Cell theory states that all living organisms are made up of one or more cells.

• Cells are the basic unit of structure and function in living organisms.

• All cells come from pre-existing cells through cell division.

• Cells contain genetic material that is passed on from parent cells to daughter cells.

• Examples include bacteria, plants, animals, and fungi, ...read more

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

• HPLC works by pumping a sample mixture through a column filled with a stationary phase, where different components interact differently with the stationary phase and elute at different times.

• The eluted components are detected by a detector and can be quantified based on their retention times.

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