A Company with Tradition and Future

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.

Semi Quantitative Test Strips

Test papers and test strips for semi quantitative analysis are extremely simple to handle. They are based on the principle of “Dip&Read”. They are available for a variety of parameters and comply with all requirements of a modern rapid test. The evaluation of these tests is carried out by a comparison with a colour scale.

Qualitative Test Papers – Without Colour Chart

Qualitative test papers come without a colour scale. With little effort, the presence of ions and other substances can be detected. The test papers change their colour when the concentration is above the specified limit of detection.

MACHEREY-NAGEL offers a versatile range of ready-to-use TLC and HPTLC layers, which are the result of 50 years of continuous research and development in thin layer chromatography.


The Comprehensive Range of TLC Products from MACHEREY-NAGEL Includes:

14963_tab_1

TLC/HPTLC glass plates

ADAMANT, SIL G or SIL HD are silica layers on glass backing. It’s hard to imagine a laboratory without our reliable TLC and HPTLC glass plates.

14963_tab_2

ALUGRAM and POLYGRAM TLC/HPTLC sheets are easy to handle, lightweight and flexible.

High performance silica on ALUGRAM Xtra sheets provides outstanding wettability for precise colourisation results. Moreover, these TLC sheets are easy to cut with scissors.

TLC Backings & Supports

mn

TLC/HPTLC plates and sheets consist of an adsorbent stationary phase on a backing support.

MACHEREY-NAGEL offers three different backings:
 

  • Glass plates
  • Aluminium sheets
  • Polyester sheets

Properties of TLC backings

Glass Plates

Glass plates are robust, heat proof and chemically resistant to all common mobile phases and visualisation reagents. They are the traditional option in TLC/HPTLC and are widely used in the pharmaceutical sector and other laboratory environments.

  • Thickness (approx.): 1.3mm
  • Weight and storage requirements: high
  • Torsional strength: ideal
  • Temperature stability: high
  • Susceptible to breakage: yes
  • Can be cut with scissors: no
  • Chemical resistance against solvents: high
  • Chemical resistance against mineral acids and concentrated ammonia: high
  • Suitability for aqueous detection reagents: depends on phases (layer)
 

Aluminium Sheets - ALUGRAM Xtra

Aluminium sheets are easy to handle, lightweight and flexible. High performance silica on ALUGRAM Xtra sheets provides outstanding wettability for precise colourisation results, even with 100% aqueous detection reagents. Moreover, ALUGRAM Xtra sheets are easy to cut with scissors. No flaking of silica occurs!

  • Thickness (approx.): 0.15mm
  • Weight and storage requirements: low
  • Torsional strength: relatively high
  • Temperature stability: high
  • Susceptible to breakage: no
  • Can be cut with scissors: yes
  • Chemical resistance against solvents: high

TLC and HPTLC

TLC_ accessories_developing_chamber_tank_20x20cm_chromatography_REF814019_003-Fisher-Banner_Crop

Features of modern TLC/HPTLC

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
14693_tab_3_banner

'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)
