Q1. What is different between HPLC and GC What is column in gc and HPLC What are chapter you have studied in msc How you prepare 1M solution of hcl
Ans. 
HPLC and GC differ in their mobile phase, stationary phase, and sample types. GC uses a gas phase while HPLC uses a liquid phase.
• HPLC uses a liquid mobile phase while GC uses a gas mobile phase

• GC uses a packed column while HPLC uses a solid or porous stationary phase

• GC is used for volatile and semi-volatile compounds while HPLC is used for non-volatile compounds

• Chapters studied in MSC depend on the program and universi...read more

Q4. What is better HPLC or gc
Ans. 
Both HPLC and GC have their own advantages and limitations, and the choice depends on the specific analytical requirements.
• HPLC is better for analyzing polar and non-volatile compounds, while GC is better for analyzing volatile compounds.

• HPLC is more sensitive and can detect lower concentrations of analytes, while GC has a faster analysis time.

• The choice between HPLC and GC also depends on the sample matrix and the req...read more

Q5. What is principal of uv
Ans. 
UV stands for ultraviolet and the principle of UV is the absorption of light in the UV region by molecules.
• UV spectroscopy is used to determine the concentration of a substance in a sample by measuring the amount of UV light absorbed by the sample.

• The principle of UV is based on the fact that molecules absorb light in the UV region of the electromagnetic spectrum.

• UV spectroscopy is commonly used in analytical chemistry

Q6. Detectors use in HPLC gc uv
Ans. 
Detectors used in HPLC, GC and UV include UV-Vis, fluorescence, refractive index, mass spectrometry, and flame ionization.
• UV-Vis detectors measure the absorbance of light by the sample at a specific wavelength.

• Fluorescence detectors measure the fluorescence emitted by the sample when excited by light.

• Refractive index detectors measure the change in refractive index of the mobile phase caused by the sample.

• Mass spectrom...read more

Questions on logical and quants

Q1. What is Bernoulli principle?
Ans. 
Bernoulli principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.
• States that as the speed of a fluid increases, its pressure decreases

• Used to explain lift in airplane wings

• Applies to various fluid dynamics situations such as flow through pipes

Q2. What is stress and how it can be measured?
Ans. 
Stress is a force acting on a material that causes deformation. It can be measured using techniques like strain gauges and load cells.
• Stress is a measure of the internal forces within a material resisting deformation.

• It is typically measured in units of force per unit area, such as Pascals or pounds per square inch.

• Common methods of measuring stress include strain gauges, load cells, and extensometers.

• Stress can be cat...read more
