Precoated Layers for HPTLC

MERCK Precoated Layers for (conventional) TLC
Test Dye Mixtures

In most cases modern TLC utilizes precoated layers. Not only are they more convenient, their quality is superior to that of layers prepared from the type of adsorbents available for self-coating.

The following list contains the more common types of precoated plates and sheets manufactured by E. MERCK. Other MERCK plates not listed here may also be ordered through CAMAG.

Test Dye Mixtures

Test dye mixtures are useful for functionality checks of individual steps in the TLC
procedure and for studying the influence of specific parameters.

CAMAG offers four different test dye mixtures:

032.8001	Test Dye Mixture I 100 mL (suitable for silica gel) Dimethyl yellow - Oracet blue 2R - Oracet red G; solvent: toluene
032.8002	Test Dye Mixture II 100 mL (suitable for silica gel and aluminium oxide) Sudan black - Artisil blue - Sudan yellow - fatty orange - fat red 7B - (Sudan black separates into two fractions); solvent: toluene
032.8003	Test Dye Mixture III 10 mL (suitable for HPTLC silica gel) Ciba F II - Indophenol - Ariabel red - Sudan blue II - Sudan IV - dimethylaminoazobenzene; solvent: toluene
032.8004	Test Dye Mixture IV 50 mL (MERCK 9352, hydrophylic) Chrysoin S - fast yellow - Amaranth - brilliant black BN; solvent: methanol - water 1:1
