What does TLC stand for in drugs?

Thin Layer (or TLC) is a “tried and true” procedure that has been used for many years in drug identification laboratories. The “thin layer” is actually a sheet of plastic coated with a porous silica material. To analyze a substance, the plant material is extracted in solvent.

How thin layer chromatography is helpful in drug analysis?

Used routinely in drug control laboratories, forensic laboratories, and as a research tool, thin layer chromatography (TLC) plays an important role in pharmaceutical drug analyses. It requires less complicated or expensive equipment than other techniques, and has the ability to be performed under field conditions .

How is chromatography used in drug testing?

9 Depending on the specific test, chromatography uses a gas or liquid carrier medium to separate the urine sample's compounds by their molecular interactions with the carrier medium (mainly by different polarities).

What is TLC used for in real life?

TLC can be used in forensic studies where body fluids , such as urine and blood can be tested for the presence of drugs. Acidic and neutral drugs can be identified by using octadecyl silica in the stationary phase, while plain silica and octadecyl silica can be used to identify basic drugs.

How is TLC used in pharmaceutical industry?

In the pharmaceutical industry, TLC is widely used in production and quality assurance applications . The presence or absence of substances can be determined qualitatively, while quantitative tests can determine the purity of a drug sample. ... Although TLC can be fully automated, it is commonly a manual technique.

How is TLC used in industry?

TLC is used by many industries and fields of research, including pharmaceutical production , clinical analysis, industrial chemistry, environmental toxicology, food chemistry, water, inorganic, and pesticide analysis, dye purity, cosmetics, plant materials, and herbal analysis.

Why silica gel is used in TLC?

Silica gel is by far the most widely used adsorbent and remains the dominant stationary phase for TLC. ... The surface of silica gel with the highest concentration of geminal and associated silanols is favored most for the chromatography of basic compounds because these silanols are less acidic.

What is TLC analysis used for?

TLC is extremely useful in Biochemical analysis such as separation or isolation of biochemical metabolites from its blood plasma, urine, body fluids, serum , etc. Thin layer chromatography can be used to identify natural products like essential oils or volatile oil, fixed oil, glycosides, waxes, alkaloids, etc.

What is difference between TLC and Hptlc?

TLC and HPTLC are two chemical techniques used to separate non-volatile components in a mixture. The key difference between TLC and HPTLC is that the absorbent material in TLC plate has large particles whereas HPTLC plates have very small particles of adsorbent material .
