Can melamine detect 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.
Who uses a hplc?
High-performance liquid chromatography (HPLC) is commonly used by chemists, biochemists, pharmaceutical scientists, and researchers in various fields for separating and analyzing compounds in a mixture. It is a valuable tool in drug development, food analysis, environmental monitoring, and quality control in industries such as pharmaceuticals, food and beverage, cosmetics, and academia.
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 the H.P.L.C. chromatography?
HPLC stands for high performance liquid chromatography. It is a liquid chromatography which involves the separation of the compounds on the basis of their polarity. It is used to analyze, identify, purify & quantify the compounds.
What analytic method is more preferrable betwee GC and HPLC?
The choice between gas chromatography (GC) and high performance liquid chromatography (HPLC) depends on the properties of the compounds being analyzed. GC is typically used for volatile compounds with low to medium molecular weight, while HPLC is more suitable for non-volatile or thermally unstable compounds. Ultimately, the decision should be based on the specific needs of the analysis, such as analyte characteristics and detection requirements.
Can melamine detect 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.
Definition of standard in HPLC?
In HPLC, a standard is a known compound with a defined chemical structure and purity used for comparison and identification purposes. Standards are essential for calibrating instruments, determining retention times, and quantifying unknown compounds in samples during analysis.
What is Difference Between HPLC UV detector Spectrophotometer uv detector?
HPLC UV detector is a component used in high-performance liquid chromatography (HPLC) to monitor eluent absorbance, while a spectrophotometer UV detector is a standalone instrument used to measure the absorption of light at different wavelengths. HPLC UV detectors are specifically tailored for chromatography applications, whereas spectrophotometer UV detectors are more versatile and used for various analytical purposes.
What is HPLC normally used to detect?
HPLC (High Performance Liquid Chromatography) is typically used to detect and quantify compounds in a mixture. It is commonly used in analytical chemistry to separate, identify, and quantify components in complex mixtures such as pharmaceuticals, chemicals, food, and environmental samples.
How do you distinguised np-hplc and rp-hplc?
NP-HPLC (normal phase HPLC) separates compounds based on their polarity, where the stationary phase is polar and the mobile phase is nonpolar. RP-HPLC (reverse phase HPLC) separates compounds based on their hydrophobicity, where the stationary phase is nonpolar and the mobile phase is polar. RP-HPLC is more commonly used due to its versatility and ability to handle a wider range of compounds.
What is drift in hplc?
In HPLC, drift refers to the gradual change in baseline signal or signal intensity over time. This can occur due to fluctuations in detector sensitivity, temperature, or system stability. Drift can affect the accuracy and precision of the analytical results and should be monitored and corrected, if necessary.

Retention time calculation for hplc?
why RT was shifting & how to RT calculation in HPLC
How HPLC is used as separation technique?
HPLC, or High Performance Liquid Chromatography, is a widely used separation technique in analytical chemistry. It separates components in a mixture based on their interactions with a stationary phase and a flowing solvent. By controlling parameters such as solvent composition, flow rate, and column material, HPLC can separate compounds with high resolution and sensitivity, making it useful for identifying and quantifying components in complex mixtures.
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".
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.
