Purify & Isolate Your Compounds Using Flash & Preparative HPLC | Dr. Sambhav Kumbhani | CSI
A flash liquid chromatography purification system, which is preparative
liquid chromatography (PLC) was used in a semi-preparative scale for the
isolation and purification of oligostilbenes from the methanol extracts of
Dipterocarpus semivestitus leaves. A method for the optimum chromatographic condition was developed on an ultra-high performance liquid chromatography (UHPLC) system. The method was transferred to the PLC with up-scaling modifications. Two stilbene trimers ampelopsin C, and -viniferin were isolated from the fractions. The purities of the compounds were determined by the UHPLC.

NIR & Raman Spectroscopy: Theory, Instrumentation & Application | D. Manikandan | CSI
Переглядів 6273 роки тому
Molecular vibrations can be exquisitely sensitive to molecular structure, and as such, measurements detecting them have gained favor for analytical purposes. Easy-to-use instrumentation to detect molecular vibrations is well developed in the mid-infrared (IR), near-IR (NIR), and visible (Raman) regions of the spectrum. The instrumentation has been optimized for each spectral range, but the phys...
UV-Vis & IR Spectroscopy Theory, Instrumentation and Applications | Dr. Rakesh Sharma | CSI

UV-Vis spectroscopy is a technique that complements the structural elucidation of molecules. A sample in solution is irradiated in UV visible range (wavelengths between 200 and 800 nm). At certain wavelengths, energy changes are produced in molecules that when returning to a resting state emit energy that is detected by the spectrophotometer allowing to identify of a functional group of the com...

Chromatographic Techniques Applied in the Purification of Biomolecules such as Proteins | CSI
Переглядів 6293 роки тому
Chromatography is an important biophysical technique that enables the separation, identification, and purification of the components of a mixture for qualitative and quantitative analysis. Proteins can be purified based on characteristics such as size and shape, total charge, hydrophobic groups present on the surface, and binding capacity with the stationary phase. Four separation techniques ba...

Importance of Impurity Profiling Regulatory Compliance in Pharma | Dr. Archana Bahuguna | CSI
Переглядів 1 тис.3 роки тому
There is an ever-increasing interest in impurities present in APIs. Nowadays, not only purity profile but also impurity profile has become mandatory according to various regulatory authorities. In the pharmaceutical world, an impurity is considered as any other inorganic or organic material, or residual solvents other than the drug substances, or ingredients, arise out of synthesis or unwanted ...

An electron impact (EI) or a chemical ionization (CI) ion source can be used to operate the mass spectrometer. Electron impact ionization delivers the highest energy to the analytes leading to ‘hard’ ionization and causes a large amount of molecular fragmentation.
