Two chromatographic methods highperformance TLC HPTLC and HPLC were developed and used for separation and quantitative determination of chlorogenic acid in green coffee bean extracts. Click to see full answer.
Normally after crude spotting of samples TLC plates are dunked in a jar for separation.
Difference between tlc and hplc. 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. TLC is thin layer chromatography. HPTLC usually mechanize this process which permits very accurate sample applications and detectionHere are some points of difference between TLC and HPTLCTLC.
The full form of TLC is thin layer chromatography. This is a time-consuming method. The important difference between HPLC and TLC is the quantitative separation of a sample is possible for HPLC whereas TLC in which there is no quantitative separation of the sample.
Here are some points of difference between HPLC and TLC. HPLC is a high-performance liquid chromatography. TLC is a thin layer chromatography.
TLC is carried out against gravity. Column chromatography is run under gravity. TLC uses for analytical purposes.
Column chromatography uses for the preparative purpose. TLC required less time to separate than the column chromatography. Column chromatography takes more time to separate than the TLC.
Two chromatographic methods high-performance TLC HPTLC and HPLC were developed and used for separation and quantitative determination of chlorogenic acid in green coffee bean extracts. For HPTLC silica gel Kieselgel 60 F 254 plates with ethyl acetatedichlormethaneformic acidacetic acidwater 10025101011 vvvvv as mobile phase were used. HPTLC is simply the application of high technology to the running of a traditional TLC glasssilica plates.
Normally after crude spotting of samples TLC plates are dunked in a jar for separation. They were 1230 815 935 and 580 for the HPLC method in the same order. The linear regression coefficient ranged from 09980999 for HPLC and from 09960998 for TLC method indicating only marginal differences between the two methods.

Key Difference TLC vs HPTLC 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. TLC is thin layer chromatography. Click to see full answer.
HPTLC is a planar chromatography were the solvent moves through a plate fixed stationary phase due to capillarity. HPTLC is an improved version of TLC while HPLC is a pump driven flow system with. The key difference between HPLC and HPTLC is that HPLC allows quantitative separation of components in a sample whereas HPTLC does not allow quantitative separation of components in a sample.
- in liquid chromatography HPLC and TLC the mobile phase is a liquid. - in HPLC the liquid mobile phase is pumped through a column packed with the stationary phase. - in TLC the liquid mobile phase moves by capillarity through a.
Difference Between HPLC and HPTLC Definition. HPLC refers to a form of liquid chromatography to separate compounds dissolved in a solution while HPTLC. HPLC is high-pressure liquid chromatography or high-performance liquid chromatography while HPTLC is.
As the name suggests gas chromatography uses gases as its mobile phase with the stationary phase either be liquid or solid. On the other hand High Performance Liquid Chromatography system uses a liquid as its mobile phase and a solid as its stationary phase in the analysis. The other differences are HPTLC TLC Layer of Sorbent 100μm 250μm Efficiency High due to smaller particle size generated Less Separations 3 - 5 cm 10 - 15 cm Analysis Time Shorter migration distance and the analysis time is greatly reduced Slower Solid support Wide choice of stationary phases like silica gel for normal phase and C8 C18 for reversed phase modes Silica gel Alumina.
High performance liquid chromatography HPLC is a form of column chromatography used to separate compounds with varied polarity. Thin layer chromatography TLC is a form of chromatography used to separate compounds with varied polarity based on a stationary and mobile phases on a silica plate. HPTLC process phase is similar to the traditional TLC separation technique.
The characteristic of the separation plate is the primary distinction between the TLC and HPTLC. The HPTLC plates depend on enhanced silica with a considerably smaller size.
