Description

Thin Layer Chromatography (TLC)

In TLC a solid phase, the adsorbent, is deposited as a thin layer onto a solid support, often glassware, plastics, or aluminium. The efficacy of this sort of chromatographic separation is determined by a number of parameters. First, the adsorbent should be extremely selective toward the compounds being separated, resulting in substantial differences in the rate of elution. Some adsorbents may be too strongly or too weakly adsorbing for the separation of any particular mixture.

Thin layer chromatography is a commonly used technique for analysing a broad range of organic and inorganic compounds due to its specific benefits such as little sample smooth, a large selection of mobile phases, flexibility in sample separation, high sample drug loading, and low price.

TLC is a strong method for screening unknown compounds in bulk medicines. It provides a rather high level of assurance that all possible components of the medicine have been isolated. The great specificity of TLC has been used for quantitative analysis by spot elution followed by spectrophotometric measurement. Some steroids, such as pioglitazone, celecoxib, and noscapine, have been determined via TLC. TLC is critical in the early stages of drug development when knowledge on impurities and degradation products in drug substance and drug product is limited.

High Performance Thin Layer Chromatography (HPTLC)

HPTLC is a rapid separation technology that can analyse a wide range of samples. This approach is useful in many ways since it is simple to use and just takes a short amount of time to examine the complex or crude sample clean-up. Without regard for time, HPTLC analyses the full chromatogram using a range of criteria. Furthermore, numerous samples and standards are developed simultaneously but independently on each plate, increasing the dependability of the results. Drugs such as ethinyl estradiol and cyproterone, alfuzosin and tramadol, and pentazocine have all been quantified using HPTLC.

High-Performance Liquid Chromatography (HPLC)

HPLC is a type of liquid chromatographic that is used to separate the complex combination of molecules found in chemical and biological systems in order to better understand the importance of individual molecules. The specificity of the HPLC method is great, and acceptable precision is also achieved. However, it should be noted that the astounding specificity, precision, and accuracy are only possible if extensive system compatibility testing are performed prior to the HPLC analysis. As a result, the cost of high sensitivity, accuracy, and reliability is also significant.

For spectroscopy, a Photodiode Array (PDA) is a lined array of discrete photodiodes on an Integrated Circuit (IC) chip. It is placed at the picture plane of a spectrometer to sense a variety of wavelengths at the same time. When utilizing a Variable Wavelength Detector (VWD), a sample must be injected multiple times with varying wavelengths to ensure that all peaks are detected. When using PDA, a wavelength range can be programmed, and all substances that absorb within this range can be discovered in a single examination. Peak purity can also be determined with a PDA sensor by comparing wavelengths inside a maximum.
