Whether GC or HPLC is a more preferable analytical method depends on the material being analyzed for, the likely concentration in which it is found, and what medium it may be in/on (water, oil, different kinds of filters, etc.) There is no single, universally applicable answer.

What is the function of pump in HPLC?
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.
How do you estimate Serratiopeptidase in Pharmaceutical products Is there a HPLC method available?
To estimate Serratiopeptidase in pharmaceutical products, HPLC (High-Performance Liquid Chromatography) is a commonly used method. A validated HPLC method can separate and quantify Serratiopeptidase in a sample, providing accurate results for quality control purposes in pharmaceutical analysis. It is essential to use appropriate standards and optimize chromatographic conditions for this analysis.
What is difference between specificity and selectivity in hplc method validation?
Specificity refers to the ability of an analytical method to accurately measure the analyte of interest in the presence of potential interfering substances. Selectivity, on the other hand, refers to the ability of the method to only detect the analyte of interest while ignoring any other components present in the sample. Both are important parameters in HPLC method validation to ensure accurate and reliable results.
Why is anthracene is used for calibration of hplc?
Anthracene is used as a calibration standard in High Performance Liquid Chromatography (HPLC) because it has a well-defined retention time and peaks in the UV-visible spectrum, making it easy to detect and quantify. Its consistent behavior helps in determining retention times, resolving power, and column efficiency during method development and troubleshooting in HPLC.
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 the definition of method development by hplc?
Method development is a process amenable to continuous improvement
What are the guidelines for method development of hplc according to ich?
the same guidelines for method validation
What has the author Stavros Kromidas written?
Stavros Kromidas has written: 'HPLC Richtig Optimiert' 'Validierung in der Analytik' -- subject(s): Analytic Chemistry, Quality control

Why reproducibility is important in hplc?
Reproducibility in HPLC ensures that results can be consistently obtained when the experiment is repeated, leading to reliable data. It allows for verification of results by other researchers and ensures the accuracy and reliability of the method. Reproducibility is crucial for validating the robustness of the HPLC method and for ensuring that results are accurate and can be trusted.
How you find out Pka value of organic compound for HPLC method develoment?
If you can't find it in the literature it can be determined experimentally by titration.
Why the pH of buffer is not changes in robustness of validation of hplc method?
it must change by (+- 0.3) to have control in pH meter error

What is assay by HPLC?
Assay by HPLC refers to using high-performance liquid chromatography (HPLC) as a technique to quantify the presence and concentration of a specific compound or analyte in a sample. HPLC separates and analyzes components within a mixture based on their interactions with the mobile and stationary phases, allowing for accurate measurement of analyte concentrations. It is commonly used in pharmaceutical, environmental, and food industries for quality control purposes.

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).
