Is UPLC the same as HPLC?
A: Both HPLC and UPLC are both liquid chromatography techniques used to separate the different components found in mixtures. However, UPLC operates at higher pressures (15,000 psi) and allows for lower particle sizes in columns, while HPLC operates at lower pressures (max <6000 psi).
Is UPLC faster than HPLC?
A: UPLC has shorter run time, so the TAT of UPLC method is generally shorter of HPLC. | Used to separate different components of a compound through identification and quantitation.

What is UPLC in pharma?
Abstract. Ultra Performance Liquid Chromatography (UPLC) is a relatively new technique giving new possibilities in liquid chromatography, especially concerning decrease of time and solvent consumption. UPLC chromatographic system is designed in a special way to withstand high system back-pressures.
Why is UPLC is with a higher efficiency than HPLC?
The key difference between HPLC and UPLC here is that UPLC has a clear advantage of HPLC, thanks to its higher pressure. This allows for shorter run times, lower solvent consumption and greater analyte separation and detection by the detector.
How do you create a calibration curve in HPLC?
Prepare the calibration curve (graph), that plot of peak area vs concentration using Excel/ relevant software. Draw a best fit straight line on your graph. Make sure the coefficient of determination/correlation is close to one. 5.
How do you create a calibration curve?
To construct the calibration curve, use a computer program to plot the data as signal vs. concentration. Use the standard deviation of the repeated measurements for each data point to make error bars. Remove portions of the curve that are non-linear, then perform a linear regression and determine the best-fit line.
How do you plot a calibration curve in HPLC?
Perform the HPLC analysis for all standard solutions and record the peak area and retention time for each component. 4. Prepare the calibration curve (graph), that plot of peak area vs concentration using Excel/ relevant software. Draw a best fit straight line on your graph.
What is the purpose of UPLC?
7.6. UPLC instruments are specially designed to resist higher back-pressures than those supported in conventional LC, providing higher speed, resolution, and sensitivity.
Why caffeine is used in HPLC calibration PDF?
Caffeine is convenient because it is not volatile, readily available, safe, has strong UV adsorption if you are using UV detector, and does not retain too long on RP columns (faster calibration).
Which standard is used for HPLC calibration?
HPLC Calibration – GMP SOP This HPLC calibration Standard Operating Procedure (SOP) describes all the individual steps necessary for calibrating a HPLC in accordance with cGMP (current good manufacturing practices).
What is UPLC analysis?
