Thin layer chromatography (HPTLC/TLC)
MACHEREY‑NAGEL is a pioneer in chromatography. We produce TLC glass plates, aluminum sheets and polyester sheets coated with silica gel, cellulose, aluminum oxide and special adsorbents in order to create TLC and HPTLC layers, that meet your needs. We are your partner in thin layer chromatography.
Thin layer chromatography (TLC) and high performance thin layer chromatography (HPTLC), also called planar chromatography are based on a multistage distribution process involving
- Suitable adsorbents (the stationary phase) coated as a thin layer onto a suitable support / backing (e.g., glass plate, polyester or aluminum sheet)
- Solvents or solvent mixtures (the mobile phase or eluent)
- Sample molecules (analytes)
Today TLC has gained increasing importance as an analytical separation technique, which is probably due to effects of instrumentation and automation. At the same time the applicability of thin layer chromatography was enhanced by development of new adsorbents and backings. MACHEREY-NAGEL offers a versatile range of ready-to-use layers, which are the result of 50 years of continuous research and development.
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 optimization of the separation due to easy change of mobile and stationary phase
