Silica Gel Extra Hard Layer (XHL) Glass Backed TLC Plates
| Silica Gel Extra Hard Layer (XHL) plates feature a newly developed binder system, resulting in an outstanding hardness of the silica layer. Due to its excellent abrasion resistance, the formation of dust on the surface of XHL Silica is minimized. Several advantages of the Silica XHL TLC: •The plate can be easily labeled with a lead pencil for clear identification. •The high abrasion resistance prevents undesired changes or damage to the layer (thickness) during transportation or handling. A dust-free plate allows convenient handling and avoids cross-contamination of the TLC chamber. The UV indicator of the XHL Silica features an increased detection sensitivity. The increased sensitivity allows for successful applications in trace analysis. Compared to Hard Layer (HL) and Soft Layer (SL) Silica plates, Extra Hard Layer (XHL) Silica demonstrates improved separation efficiency, since the particle size distribution of the silica was optimized. The selectivity of XHL Silica is different compared to HL and SL Silica. Thus the chromatographer now can choose from 3 different types of Silica plates (XHL, HL, and SL) in order to optimize a given chromatographic experiment. |
