HPLC works when a reservoir holds the solvent and then it is sent to the pump manager.Next it goes to the HPLC coloumn .After it goes through there it usually ends in the detector than waste. Generally the stationary phase in the HPLC column is made up of alkyl coated silica making it relatively non-polar. Due to this the technique is also called reversed-phase HPLC.
mixture of enantiomers can be separated by HPLC
Yes, melamine can be detected by HPLC (High Performance Liquid Chromatography). HPLC is a common analytical technique used to separate and quantify compounds in a mixture, including melamine. Detection methods such as UV-Vis spectroscopy or mass spectrometry can be used in conjunction with HPLC to identify and quantify melamine accurately.
GC can give very resolved sharp peaks with short run time compared to hplc. additionally, there is less compatibility issue in setting an MS up to a GC than HPLC
HPLC is used to analyze, identify, purify and quantify organic compounds.
An ordinary liquid pump cannot be used in HPLC systems because HPLC requires pumps that can generate high pressure to push solvents through the column at a constant and precise flow rate. Ordinary pumps do not provide the level of pressure and flow rate control needed for HPLC separations, which can negatively impact the accuracy and reproducibility of chromatographic results. HPLC pumps are specifically designed to handle the high pressures and flow rates required for efficient separations.
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).

"RS-HPLC method" means "Related Substance HPLC Method".
You can purchase used HPLC detectors and other equipment from the usedhplc website or from the ebay bidding website. Alternatively you can buy HPLC detectors from the equipnet website.
In HPLC RRT means Relative Retention Time and RRF is Relative Response Factor
The dead volume in HPLC is 137.45. The dead volume in science is used in retention measurements and also in thermodynamic studies and the abbreviation HPLC stands for High Pressure Liquid Chromatography.
Normal phase HPLC separates compounds based on their polarity, with the stationary phase being polar and the mobile phase being nonpolar. Reverse phase HPLC separates compounds based on their hydrophobicity, with the stationary phase being nonpolar and the mobile phase being polar. Normal phase HPLC is typically used for separating polar compounds, while reverse phase HPLC is used for separating nonpolar compounds.

HPLC Column is one type of tube containing a stationary phase react with mobile phase to detect peak
GC can give very resolved sharp peaks with short run time compared to hplc. additionally, there is less compatibility issue in setting an MS up to a GC than HPLC
HPLC (High-performance liquid chromatography) is generally considered more advanced than GC (Gas chromatography) due to its broader application range, higher sensitivity, and ability to separate a wider range of compounds. HPLC is often preferred for analyzing complex mixtures and compounds that are not volatile.
