Jet is a type of aircraft that uses jet propulsion to move forward.

• Jet engines work by taking in air, compressing it, mixing it with fuel, and igniting it to create a high-pressure exhaust that propels the aircraft forward.

• Jets can fly at high altitudes and speeds, making them ideal for long-distance travel.

• Examples of jet aircraft include commercial airliners like the Boeing 747 and military fighter jets like the F-16.

GC test can be skipped in certain medical conditions.

• If the patient has a medical condition that can interfere with the accuracy of the test, such as liver disease or kidney failure.

• If the patient is taking medication that can affect the test results, such as antibiotics or antifungal drugs.

• If the patient has recently received a vaccine that contains live viruses, such as the MMR vaccine.

• If the patient has a low risk of infection or if the test is not necessary for diagnosis ...read more

Split ratio is important for accurate measurement of samples in analytical techniques.

• Split ratio determines the amount of sample that is introduced into the analytical instrument.

• It helps in reducing the sample size and improving the sensitivity of the analysis.

• Split ratio also helps in preventing instrument overload and prolonging the life of the instrument.

• For example, in gas chromatography, split ratio is used to control the amount of sample that enters the column.

• In mass...read more

Pharma guidelines and Agency

• Pharma guidelines refer to the set of rules and regulations that pharmaceutical companies must follow in order to ensure the safety and efficacy of their products.

• These guidelines are established by regulatory agencies such as the Food and Drug Administration (FDA) in the United States or the European Medicines Agency (EMA) in Europe.

• The guidelines cover various aspects including drug development, clinical trials, manufacturing practices, labeling,...read more

Glasswool is necessary for insulation and soundproofing purposes.

• Glasswool is a type of insulation material made from recycled glass fibers.

• It is used to insulate buildings, pipes, and other structures to reduce heat loss and save energy.

• Glasswool is also used for soundproofing to reduce noise pollution.

• It is lightweight, easy to install, and has good fire resistance properties.

• Glasswool is a cost-effective solution for improving energy efficiency and reducing environmental i...read more

Split ratio refers to the ratio of sample to solvent in a chromatography experiment.

• It is used in chromatography experiments to determine the amount of sample and solvent needed.

• It is expressed as a ratio, such as 1:10 or 1:100.

• The split ratio affects the sensitivity and resolution of the experiment.

• For example, a higher split ratio will result in a more dilute sample and lower sensitivity.

HPLC and GC are analytical techniques used to separate and analyze components in a mixture based on their interactions with a stationary phase and mobile phase.

• HPLC stands for High Performance Liquid Chromatography, where the sample is dissolved in a liquid mobile phase and separated based on interactions with a stationary phase.

• GC stands for Gas Chromatography, where the sample is vaporized and separated based on interactions with a stationary phase inside a column.

• Both tech...read more
