Differbetween
HPLC is a chromatographic technique done through a column while HPTLC is planar. ... HPTLC is an improved version of TLC, while HPLC is a pump driven flow system with a stationary phase filled column. HPLC and HPTLC are based on similar chromatographic principles and are high performance techniques.

What is the difference between HPLC and Hptlc?
HPLC refers to a form of liquid chromatography to separate compounds dissolved in a solution, while HPTLC refers to a most advanced form of planar chromatography. Thus, this is the main difference between HPLC and HPTLC.
What is the principle of Hptlc?
Principle of HPTLC have similar approach and employ the same physical principles of TLC (adsorption chromatography) i.e. the principleof separation is adsorption. The mobile phase solvent flows through because of capillary action. The components move according to their affinities towards the adsorbent.
What is the true about Hptlc?
High-performance thin-layer chromatography (HPTLC) is an enhanced form of thin-layer chromatography (TLC). ... The spot capacity (analogous to peak capacity in HPLC) can be increased by developing the plate with two different solvents, using two-dimensional chromatography.
What is the difference between column chromatography and HPLC?
High performance liquid chromatography is basically a highly improved form of column chromatography. Instead of a solvent being allowed to drip through a column under gravity, it is forced through under high pressures of up to 400 atmospheres. That makes it much faster.
How does the HPLC work?
How Does HPLC Work? ... HPLC is a highly improved form of column chromatography. A pump forces a solvent through a column under high pressures of up to 400 atmospheres. The column packing material or adsorbent or stationary phase is typically a granular material made of solid particles such as silica or polymers.
What is Hptlc fingerprinting?
High-performance thin-layer chromatography (HPTLC) is a powerful analytical technique which is wonderfully suitable for qualitative and quantitative analytical tasks. ... The development of chromatographic fingerprints plays an important role in the quality control of complex herbal medicines.
Which detector is used in Hptlc?
The CAMAG TLC Scanner 4 (densitometer) is the most advanced workstation for densitometric evaluation of TLC/HPTLC chromatograms and other planar objects. The chromatogram is evaluated under white or UV light.
What is the full form of Hptlc?
HPTLC (high-performance thin layer chromatography) is a sophisticated form of TLC, which provides superior separation efficiency. The HPTLC concept includes validated methods for qualitative and quantitative analysis, and fulfills all quality requirements for use in fully regulated environments.
Why is HPLC used?
High-performance liquid chromatography (HPLC) is a chromatographic technique used to split a mixture of compounds in the fields of analytical chemistry, biochemistry and industrial. The main purposes for using HPLC are for identifying, quantifying and purifying the individual components of the mixture.
What is Rf value?
RF value (in chromatography) The distance travelled by a given component divided by the distance travelled by the solvent front. For a given system at a known temperature, it is a characteristic of the component and can be used to identify components.
How do you perform a Hptlc?
The choice of the application technique and the device depend on the requirements. Spot wise sample application using a fixed volume capillary is the simplest way. Sample volumes of 0.5 to 5 μL can be applied as spots onto conventional layers without drying, on HPTLC layers it is up to 1 μL per spot.
What is the meaning of chromatography?
: a process in which a chemical mixture carried by a liquid or gas is separated into components as a result of differential distribution of the solutes as they flow around or over a stationary liquid or solid phase.
