How do you optimise peak separation in HPLC?
we can optimize peak separation by optimizing the HPLC conditions for standard solutions.
How do you distinguised np-hplc and rp-hplc?
NP-HPLC is "Normal Phase" HPLC, wherein the solvents used are less polar than the substrate in the HPLC column (e.g. using hexane or dichloromethane with a silica HPLC column). RP-HPLC is "Reverse-Phase" HPLC, wherein the solvents used are more polar than the substrate in the HPLC column (e.g. using Water and Methanol with a octadecylsilane (ODS or C18) column).
Which one is advanced gc or hplc?
HPLC is advanced
What is C8 and C18?
HPLC columns. (HPLC - High Performance Liquid Chromatography.)
What is difference bet GLC and HPLC?
GLC has a stationary liquid phase and gas moving phase HPLC had a stationary solid phase and liquid moving phase HPLC is done under high pressure. HPLC can be used for thermally unstable compounds as opposed to GLC HPLC can be used for polar or low volatile compounds as opposed to GLC
How do you optimise peak separation in HPLC?
we can optimize peak separation by optimizing the HPLC conditions for standard solutions.
What is the definition of method development by hplc?
Method development is a process amenable to continuous improvement
Why propyl paraben used in HPLC calibration?
propyl paraben being a stable compound with reproducible chromatographic parameters used as a internal standard for the calibration of the HPLC systems
How you can analyze pregabalin on HPLC with UV detector?
We can quantitatively analyse pregabalin on hplc with uv detector, wavelength will be 210 n.m. and mobile phase will be 5 % acetonitrile. standard & sample solution preparation should be in mobile phase.

How will calculate rrf in hplc?
RRF= (area or height peak X amount IS)/(area or height X amount pk) IS is the internal standard
Retention time calculation for hplc?
why RT was shifting & how to RT calculation in HPLC
What is C8 and C18?
HPLC columns. (HPLC - High Performance Liquid Chromatography.)
What type of species can be separated by HPLC but not by gas liquid chromatography?
mixture of enantiomers can be separated by HPLC
What is rs-hplc?
"RS-HPLC method" means "Related Substance HPLC Method".
What is difference bet GLC and HPLC?
GLC has a stationary liquid phase and gas moving phase HPLC had a stationary solid phase and liquid moving phase HPLC is done under high pressure. HPLC can be used for thermally unstable compounds as opposed to GLC HPLC can be used for polar or low volatile compounds as opposed to GLC
