A high-performance liquid chromatography, or HPLC, refers to a technique in analytic chemistry that is used to separate the components in a mixture. The pump in HPLC passes a pressurized liquid solvent that contains the sample mixture through a column filled with a solid adsorbent material.

What type of species can be separated by HPLC but not by gas liquid chromatography?
mixture of enantiomers can be separated by HPLC
Retention time in Hplc?
The Time-Taken the sample Or elute in the column is called the retention time in hplc.
Why volatile compounds are analysed in gc but not in hplc?
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
Which are the top commercial uses for HPLC?
HPLC is used to analyze, identify, purify and quantify organic compounds.
Who uses a hplc?
Analytical chemists and Polymer Chemists
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 are the HPLC Calibration parameters and elaborate it?
1. Flow rate 2. Temp. of column 3. Detector function 4. Resolution
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.)
Definition of standard in HPLC?
Answer: HPLC standards are an indispensible tool for analytical HPLC applications. They are used to monitor column performance & calibrate detector response.
What type of species can be separated by HPLC but not by gas liquid chromatography?
mixture of enantiomers can be separated by HPLC
How the hearts function?
PUMP
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
Where can one purchase HPLC detectors?
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.
Retention time in Hplc?
The Time-Taken the sample Or elute in the column is called the retention time in hplc.
