Macherey-Nagel

MACHEREY-NAGEL was founded in 1911 in Düren as a specialist manufacturer of filter papers. Since that time, we have evolved into an innovative international company for chemical and biomolecular analysis. MACHEREY-NAGEL stands for innovative and creative solutions which we have a penchant for developing in-house. In addition to the “traditional” departments, such as research, production, sales and media design, we also have departments such as mechanical engineering and device development as well as our own joinery.

Our products are among the world’s most reliable analytical systems. They are used, for example, in industry, healthcare, biotechnology, environmental analysis and research. Numerous patents and international certifications underline the high quality of our products and the competence of our employees.

Features of modern TLC/HPTLC

TLC and HPTLC Image

The success of thin layer chromatography as a highly efficient microanalytical separation method is based on a large number of advantageous properties:

  • High sample throughput in a short time
  • Suitable for screening tests
  • Pilot procedure for HPLC and Flash chromatography
  • After separation the analytical information can be stored for a longer period of time (the TLC ready-to-use layer acts as storage medium for data)
  • Separated substances can be subjected to subsequent analytical procedures (e.g., IR, MS) at a later date
  • Rapid and cost-efficient optimisation of the separation due to easy change of mobile and stationary phase
Diagram

TLC and HPTLC are both widely used terms in laboratory environments, but what is the difference? At MACHEREY-NAGEL, we define 'HPTLC' where at least one of the following criteria is being fulfilled:

  • Layers with particle size 2 to 10μm
  • Layers prefixed with 'Nano'
  • Modified layers

Narrow fractionation of HPTLC silica particles allows:

  • Sharper separations
  • Shorter developing times
  • Shorter migration distances
  • Smaller samples needed
  • Increased detection sensitivity (compared to TLC)
