Thin Layer Chromatography TLC Testing Services
Thin layer chromatography (TLC) is a chromatographic technique in which the stationary phase is a thin adsorbent layer, coated onto an inert supporting plate. The samples are deposited as spots into the plate, which is dipped into an eluent. The eluent moves up the thin adsorbent by capillary action and elutes analyte molecules at varying rates resulting in their separation.

What Is Thin Layer Chromatography TLC?
Thin-Layer Chromatography (TLC) is a simple, rapid, and cost-effective analytical technique used to separate and identify components in a mixture. It operates on the principle of differential migration of compounds on a stationary phase under the influence of a mobile phase, allowing qualitative analysis of complex samples.
TLC is widely used in pharmaceuticals, chemicals, food testing, and environmental analysis for compound identification, purity checks, and reaction monitoring. Its versatility, minimal sample requirement, and quick results make it a valuable tool for routine laboratory analysis and research applications.

Our Testing Procedure
Sample Preparation
The sample is dissolved in a suitable solvent and prepared for spotting on the TLC plate.
1Plate Spotting
Small spots of the sample and standards are applied onto the stationary phase plate.
2Development
The plate is placed in a solvent chamber allowing compounds to migrate and separate.
3Visualization & Analysis
Separated spots are visualized and analyzed to identify compounds and calculate Rf values.

Thin Layer Chromatography TLC FAQs
Thin-Layer Chromatography is an analytical technique used to separate and identify compounds in a mixture. It works based on differential movement of substances on a stationary phase under the influence of a solvent.
TLC can analyze organic compounds, pharmaceuticals, food components, and environmental samples. It is widely used for qualitative analysis and identification of substances in various industries and research applications.
Rf value is the ratio of the distance traveled by a compound to the distance traveled by the solvent front. It is used to identify substances by comparing with known standards under similar conditions.
Factors include solvent composition, stationary phase, sample concentration, temperature, and humidity. Proper control of these parameters ensures effective separation and accurate results.
Compounds are visualized using UV light or chemical reagents that produce visible spots. Some compounds naturally fluoresce under UV light, while others require staining for detection.
