PHARMACEUTICAL APPLICATIONS OF HPTLC AND METHOD VALIDATION

  HPTLC as an analytical technique has applications in multiple fields. It can be used for qualification and quantification of samples in sectors like Pharmaceuticals, Herbals, Cosmetic, Food and Forensic sciences and it can also be used as a fingerprint analysis technique in the above fields.  HPTLC instrumentation  involves different modules for application, development, image documentation and detection. Application of HPTLC in pharmaceutical field: As all the compounds which are analysed by TLC can be analysed using HPTLC, it has a wide variety of applications in the Pharmaceutical field. 1.         Impurity profiling 2.         Content Uniformity 3.         Forced Degradation 4.         Stability 5.         Limit test 6.         Assay Validation...

Dyes & Dye Intermediates Analysis by HPTLC?

 Dye and dye intermediates have applications in paints, inks, textiles, paper and plastic industry. They are used as raw material for direct dyes, acid dyes and reactive dyes. India is a major exporter of synthetic and organic dyes. Dyes are classified into many types such as acid dyes, basic dyes, direct dyes, disperse dyes, azo dyes, and sulphur dyes etc. Dyes are susceptible to adulteration hence it becomes mandatory to analyse dyes. HPTLC being a versatile technique proves to be just the right analytical tool to analyse without much hassle. Dyes are non-volatile organic substances and so best suited for HPTLC analysis . One such example of dyes analysis by HPTLC is comparison between the formulation and the dyes used in it. Here disperse dyes formulation was compared with standard dyes used in the commercial product. Disperse orange 288, Disperse Orange 61, Disperse violet 93.1 and disperse blue 291.1 along with the formulation were applied on HPTLC plate. The plate w...

What Is CAMAG HPTLC And How Is It Helpful In Chromatography

  High Performance Thin Layer Chromatography (HPTLC) is chromatographic technique based on the principle of planar chromatography. It is a modernized version of Thin Layer Chromatography (TLC) with enhanced capabilities. CAMAG is Swiss based company manufacturing TLC since 1961. They are the world leaders in instrumental HPTLC. First Manual TLC was into existence. Over the years the technique has evolved from manual to semi-automatic which now has upgraded to fully automated HPTLC PRO system in 2019 for routine quality control. HPTLC not only achieves miniaturization of chromatograms but most importantly better resolution and reproducibility with a state of art software for documentation and control over the instrumentation. It is cost effective with high throughput. Up to 15 samples can be run on plate at a time and with less solvent consumption. CAMAG HPTLC  has modules of instruments combined to form a system. Each step has a designated module catering to analyst...

Types Of Analyses Done Using HPTLC

HPTLC High Performance Thin Layer Chromatography is a modernized version of TLC technique. The underlying principle remains the same i.e. planar chromatography. HPTLC gives better separation and resolution of bands compared to TLC technique. Also, quantification aspect is added in HPTLC which an analyst won’t achieve using conventional TLC. HPTLC has a wide area of applications ranging from herbal, food, pharmaceuticals to forensics. Let us have a look at what kind of analyses can be done using  CAMAG HPTLC . Application of herbals involve HPTLC fingerprinting where there is no requirement of marker/standard. Fingerprint is the individual chromatographic track representing all the constituents in a plant sample. This allows us to differentiate at species to species level. Class of compounds is a phytochemical test confirming the presence of functional groups such as phenols, flavonoids, alkaloids and antioxidants etc. This type of analysis is qualitative. Applications in the field ...
