| Description | SIL G unmodified standard silica layers for TLC, glass plates/ POLYGRAM® Linear- K: give rapid, precise recognition. The pre-adsorbent layer is thicker than the silica layer and functions like a sponge that pre-concentrates the sample before it reacts with the silica layer. This allows the user to apply sample volumes that would not be possible with standard TLC-plates. The symbol for silica gel is K (from the German Kieselgel). followed by a classification designation: - K5 10-12µm silica, with pore size 150 Å - K6 10-12µm silica, with pore size 60 Å - High-performance silica is prefixed with the letters HP: HP-K 4.5 µm silica, pore size 60 Å - Reversed-phase plates with a bonded alkyl group are represented by a K, followed by the length of the alkyl chain KC-18 10-12µm Silica 60 Å, octadecyl bonded phase Further identification information for a particular plate can be found from the following letter codes: - L pre-adsorbent layer for the easier application of larger volumes. Compresses each sample into a narrow horizontal band, so also known as Linear-K, prefix L. - D channelled plates with separate lanes. 2mm clear glass channels separate the individual sample lanes to prevent the samples becoming mixed, so D for Division. - F fluorescent indicator: fluorescent plates glow bright green under UV light. Samples that absorb UV at 254nm are recognised by fluorescence quenching. - M microscope slide, plate size 25/75mm. - P preparative layer. Has a thickness of 500µm or 1000µm for large samples. These letter codes enable easy, rapid identifcation of all TLC plates, for example PLK6DF = preparative K6 silica 60 Å pore diameter, separate lanes, fluorescent indicator and pre-adsorbent layer. glass plates, POLYGRAM®, ALUGRAM® silica 60, specific surface (BET) ~500m²/g, mean pore size 60 Å, specific pore volume 0.75 ml/g, particle size 5 to 17µm; standard grade; thickness of layer for analytical plates 0.25mm, for preparative plates 0.5 and 1mm; for 2mm preparative layers a slightly coarser material is used indicators: manganese activated zinc silicate with green fluorescence for short-wave UV (254nm); special inorganic fluorescent pigment with blue fluorescence for long-wave UV (366nm) binders: highly polymeric products, which are stable in almost all organic solvents and resistant towards aggressive visualisation reagents; binder system for Polygram® sheets is also completely stable in purely aqueous eluents available as glass plates, Polygram polyester sheets and Alugram aluminium sheets. Available as glass plates with or without fluorescent indicator (UV254). Type ALUGRAM® aluminium sheets SIL G Plate format 20 x 20 cm Gel thickness 0.20 mm |
