Merck’s HPTLC silica plates work three times faster than conventional TLC plates – and they’re more sensitive. This makes our HPTLC plates perfect for advanced separations. HPTLC and TLC plates use the same type of silica gel 60. But in HPTLC particle sizes range between 4-8 μm, and the mean particle size measures 5-6 μm. This yields a smoother surface and a higher separation power than conventional TLC plates. Highly compact sample bands (thanks to lower band diffusion) and an thin 200 µm layer translate into greatly enhanced sensitivity. 目录编号 产品 105547 HPTLC silica gel 60 ( 高效硅胶层析板 ) 25 Aluminium sheets 20 x 20 cm 105631 HPTLC Silica gel 60 ( 硅胶薄层层析板 ) 25 Glass plates 10 x 10 cm 105641 HPTLC Silica gel 60 ( 高效硅胶层析板 ) 50 Glass plates 20 x 10 cm 105633 HPTLC Silica gel 60 ( 高效硅胶层析板 ) 100 Glass plates 10 x 10 cm 105556 HPTLC Silica gel 60 F254 ( 高效硅胶薄层层析板 ) 20 Aluminium sheets 5 x 7.5 cm 105548 HPTLC Silica gel 60 F254 ( 高效硅胶层析板 含荧光指示剂 ) 25 Aluminium sheets 20 x 20 cm Its small pore size of 100 Å provides larger surface area enabling additional 105628 HPTLC Silica gel 60 F254 ( 硅胶薄层层析板 含荧光指示剂 ) 25 Glass plates 10 x 10 cm 105642 HPTLC Silica gel 60 F254 ( 硅胶薄层层析板 含荧光指示剂 ) 50 Glass plates 20 x 10 cm 105629 HPTLC Silica gel 60 F254 ( 硅胶薄层层析板 含荧光指示剂 ) 100 Glass plates 10 x 10 cm 105649 HPTLC silica gel 60 F254 ( HPTLC硅胶60 F254 ) Glass Plates 20 x 10 cm 111764 HPTLC Silica gel 60 F254 AMD,extra thin ( 硅胶薄层层析板 含荧光指示剂 ) 25 Glass plates 20 x 10 cm for AMD acc. to DIN 38407-F11 115696 HPTLC Silica gel 60 F254s ( 硅胶薄层层析板 含荧光指示剂 亲水性处理 ) 25 Glass plates 20 x 10 cm 105644 HPTLC Silica gel 60 Multiformat pre-scored to 5 x 5 cm ( 硅胶薄层层析板 ) 100 Glass plates 10 x 10 cm 113749 HPTLC Silica gel 60 with concentrating zone 20 x 2.5 cm ( 高效薄层层析板 ) 50 Glass plates 20 x 10 cm 115552 HPTLC Silica gel 60 WR F254s ( 硅胶薄层层析板 含荧光指示剂 亲水性处理 ) 25 Glass plates 20 x 10 cm 112363 HPTLC Silica gel 60 WRF254s AMD extra thin ( 硅胶薄层层析板 含荧光指示剂 亲水性处理 ) 25 Glass plates 20 x 10 cm for AMD acc. to DIN 38407-F11 105616 HPTLC Silica gel F254 ( 硅胶薄层层析板 含荧光指示剂 ) 25 Glass plates 5 x 10 cm 超薄单石型硅平板(UTLC) 105007 UTLC Silica gel monolithic,10 µm ( 整体化硅胶层析板 ) 制备级层析片(PLC) Preparative thin-layer plates allow users to separate samples that vary greatly in size – from grams down to milligrams. Available with or without a fluorescence indicator, PLC plates come as thin as 0.5 cm and as thick as 2 cm. They also use the same proven Merck silica-binder technology as in analytical TLC plates. In PLC, samples are typically applied as a band across the entire width of the plate. UV detection is used almost exclusively to render substances visible. To isolate the substance by extraction, users can simply scrape the spot from the layer. 目录编号 产品 105788 PLC Aluminium oxide 60 F254, 1.5 mm ( 制备氧化铝层析板 ) 12 Glass plates 20 x 20 cm 105726 PLC Aluminium oxide 150 F254, 1.5 mm ( 氧化铝制备层析板 ) 12 Glass plates 20 x 20 cm 105744 PLC Silica gel 60 F254, 0.5 mm ( 硅胶薄层层析板 含荧光指示剂 ) 20 Glass plates 20 x 20 cm 113895 PLC Silica gel 60 F254, 1 mm ( 制备薄层层析板 含荧光指示剂 ) 15 Glass plates 20 x 20 cm 105717 PLC Silica gel 60 F254, 2 mm ( 硅胶薄层层析板 含荧光指示剂 ) 12 Glass plates 20 x 20 cm 105637 PLC Silica gel 60 F254+366, 2 mm ( 硅胶薄层层析板 含254+366 荧光指示剂 2mm ) 12 Glass plates 20 x 20 cm 105434 PLC Silica gel 60 RP-18 F254s, 1 mm ( 制备层析板RP-18 含荧光指示剂 ) 15 Glass plates 20 x 20 cm 113894 PLC Silica gel 60, 0.5 mm ( 薄层分析用硅胶片 ) 20 Glass plates 20 x 20 cm 105745 PLC Silica gel 60, 2 mm ( 制备薄层层析板 ) 12 Glass plates 20 x 20 cm CN-, Diol-, NH2- 修饰硅平板(TLC和HPTLC) These plates tackle extraordinary separation challenges. Our NH2, CN, and diol-modified silica sorbents are less polar then conventional silica phases, making them ideal for separating hydrophilic or charged substances. Our moderately polar cyano- and diol-modified silica plates can be used for both normal phase and reversed phase systems. An alternative to PEI cellulose, amino-modified NH2 plates provide weak basic ion exchange characteristics with special selectivity for charged compounds. Most modified plates contain F254s, the blue fluorescent, acid stable UV indicator. Fluorescence quenching is used on samples that absorb shortwave UV at 254 nm. 目录编号 产品 116464 HPTLC Silica gel 60 CN F254s ( 硅胶薄层层析板 氰基 含F254s荧光指示剂 ) 25 Glass plates 10 x 10 cm 112668 HPTLC Silica gel 60 DIOL F254s ( 薄层分析用层析片 ) 25 Glass plates 10 x 10 cm 105636 HPTLC Silica gel 60 DIOL F254s ( Diol薄层层析板 含荧光指示剂 ) 25 Glass plates 20 x 10 cm 112572 HPTLC Silica gel 60 NH2 ( 高效薄层层析板 ) 25 Glass plates 20 x 10 cm 113192 HPTLC Silica gel 60 NH2 F254s ( 高效薄层层析板 ) 25 Glass plates 20 x 10 cm 115647 HPTLC Silica gel 60 NH2F254s ( 高效薄层层析板NH2含荧光指示剂 ) 25 Glass plates 10 x 10 cm 105533 TLC Silice gel 60 NH2 F254s ( NH2层析板 含荧光指示剂 ) 20 Aluminium sheets 20 x 20 cm 氧化铝薄层板 (TLC) These plates are used to analyze basic and neutral compounds at different pH levels.

Merck concentrating zone plates are based on different adsorption properties of two adsorbents. The first is a large pore concentrating adsorbent where the samples are applied; the second is a selective layer for separation. Regardless of the spots’ shape, size, or position, the sample always concentrates as a narrow band where the two adsorbents overlap and where the separation starts. 目录编号 产品 113187 HPTLC Silica gel 60 F254 with concentrating zone 5 x 2.5 cm ( 高效薄层层析板 ) 25 Glass plates 5 x 10 cm 113727 HPTLC Silica gel 60 F254 with concentrating zone 10 x 2.5 cm ( 高效层析硅胶片 ) 25 Glass plates 10 x 10 cm 113728 HPTLC Silica gel 60 F254 with concentrating zone 20 x 2.5 cm ( 高效硅胶层析片 ) 50 Glass plates 20 x 10 cm 115498 HPTLC Silica gel 60 RP-18 F254s with concentrating zone 20 x 2.5 cm ( 薄层层析板 RP-18 含荧光指示剂 ) 25 Glass plates 20 x 10 cm 115037 HPTLC Silica gel 60 RP-18 with concentrating zone 20 x 2.5 cm ( 高效薄层层析板 ) 25 Glass plates 20 x 10 cm for PAH determination acc. to DIN 38409-H13 113748 HPTLC Silica gel 60 with concentrating zone 10 x 2.5 cm ( 高级率层析硅胶片 ) 25 Glass plates 10 x 10 cm 113794 PLC Silica gel 60 F254, 0.5 mm with concentrating zone 20 x 4 cm ( 制备层析硅胶片 含荧光指示剂 ) 20 Glass plates 20 x 20 cm 113792 PLC Silica gel 60 F254, 1 mm with concentrating zone 20 x 4 cm ( 制备层析硅胶片 含荧光指示剂 ) 15 Glass plates 20 x 20 cm 113793 PLC Silica gel 60 F254, 2 mm with concentrating zone 20 x 4 cm ( 制备层析硅胶片 含荧光指示剂 ) 12 Glass plates 20 x 20 cm 111846 TLC Silica gel 60 F254 with concentrating zone 10 x 2.5 cm ( 薄层分析用硅胶片 ) 50 Glass plates 10 x 20 cm 105583 TLC Silica gel 60 F254 with concentrating zone 20 x 2.5 cm ( 60 F254s硅胶薄层层析板，浓缩区20 x 2.5 cm ) 25 Aluminium sheets 20 x 20 cm 111798 TLC Silica gel 60 F254 with concentrating zone 20 x 2.5 cm ( 硅胶薄层层析板 含荧光指示剂 ) 25 Glass plates 20 x 20 cm 111845 TLC Silica gel 60 with concentrating zone 2.5 x 20 cm ( 60硅胶薄层层析板，浓缩区2.5 x 20 cm ) 25 Glass plates 20 x 20 cm 111844 TLC Silica gel 60 with concentrating zone 10 x 2.5 cm ( 薄层分析用硅胶片 ) 50 Glass plates 10 x 20 cm 105582 TLC Silica gel 60 with concentrating zone 20 x 2.5 cm ( 硅胶薄层层析板 ) 25 Aluminium sheets 20 x 20 cm HPTLC特纯度平板添加到分类最爱 Ideal for advanced pharmacopoeia applications, this high-performance plate keeps separations free of contamination. The plate is highly pure and exhibits minimal background, even with middle-polar solvent systems. Its separation performance is an exact match to the related HPTLC plate product. Based on the proven HPTLC 60 F254 plate, the HPTLC premium purity plate comes carefully wrapped in a special, plastic-coated aluminum foil. This prevents plasticizers (such as phthalates) from leaving deposits. Without the foil, the plasticizers could appear as an “unknown extra zone” when mid-polar solvent systems (such as toluene/ethyl acetate (95/5)) are in use, and they could be stained by derivatization reagents (such as anis aldehyde). 目录编号 产品 105648 HPTLC Silica gel 60 F254 Premium Purity ( HPTLC Silica gel 60_F254 Premium Purity ) 50 Glass plates 20 x 10 cm Multiformat Plates (TLC和HPTLC) These pre-scored glass plates fold into smaller formats with just one easy snap of the fingers. 目录编号 产品 105635 HPTLC Silica gel 60 F254 Multiformat pre-scored to 5 x 5 cm ( 硅胶高效层析板 ) ex Glass plates 10 x 10 cm 105620 TLC Silica gel 60 F254 Multiformat prescored to 5 x 10 cm ( 硅胶薄层层析板 含荧光指示剂 含多种规格片 ) 25 Glass plates 20 x 20 cm, 105608 TLC Silica gel 60 F254 Multiformat pre-scored to 5 x 20 cm ( 硅胶薄层层析板 含荧光指示剂 ) 20 Glass plates 20 x 20 cm GLP平板 (TLC和HPTLC) These plates feature individual laser coding for GLP applications.

It allows to carry out almost every type of separation by suitable choice of the mobile phase. Merck classical silica TLC plates are based on a combination of Merck silica gel 60 and the addition of a unique polymeric binder resulting in a very adherent and hard surface that will not crack or blister and even allow writing with a pencil on the surface without risk to damage the layer. The smooth and extremely dense plate surface ensures narrow bands for maximum separation efficiency with lowest background noise e.g. when performing scanning densitometry. http://www.merck-chemicals.com.cn/classical-silica-tlc-plates-tlc/chinese/c_zWmb.s1LzOQAAAEWuOAfVhTl RP修饰硅平板 (TLC和HPTLC) These plates serve two purposes: act as a pilot method for HPLC and allow to choose various solvent system for special separations. RP-modified silica layers from Merck are well suited for many separation challenges that unmodified silica cannot overcome. These layers use aqueous solvent systems to separate extremely non-polar substances and analyze particular polar substances that can adapt to ion-pair chromatography. What’s more, RP-modified silica layers are less dependent on atmospheric humidity. Unlike unmodified silica, RP-phases do not exhibit catalytic activity. This makes them the plates of choice for unstable substance that tend to experience oxidative degradation. 目录编号 产品 113726 HPTLC Silica gel 60 RP-2 F254s ( 高效薄层层析板 ) 25 Glass plates 10 x 10 cm 105914 HPTLC Silica gel 60 RP-18 ( 高效RP-18 薄层层析板 ) 25 Glass plates 20 x 10 cm 113724 HPTLC Silica gel 60 RP-18 F254s ( 高级率逆相层析硅胶片 ) 25 Glass plates 10 x 10 cm 114296 HPTLC Silica gel 60 RP-18 W ( 高效薄层层析板 ) 25 Glass paltes 10 x 20 cm 113124 HPTLC Silica gel 60 RP-18 WF254s ( 高效薄层层析板 亲水性处理 含荧光指示剂 ) 25 Glass plates 10 x 10 cm 113725 HPTLC Silice gel 60 RP-8 F254s ( 高效薄层层析板 ) 25 Glass plates 10 x 10 cm 105746 TLC Silica gel 60 RP-2 ( RP-2 硅胶薄层层析板 ) 25 Glass plates 20 x 20 cm 105747 TLC Silica gel 60 RP-2 F254 (silanized) 25 Glass plates 20*20cm ( TLC硅胶60 RP-2 F254硅烷化25玻板，20*20cm ) 115684 TLC Silica gel 60 RP-8 F254s ( RP-8薄层层析板 含荧光指示剂 ) 25 Glass plates 5 x 10 cm 115388 TLC Silica gel 60 RP-8 F254s ( 薄层层析板 RP-8 含荧光指示剂 ) 25 Glass plates 20 x 20 cm 115424 TLC Silica gel 60 RP-8 F254s ( 薄层层析板 RP-8 含荧光指示剂 ) 50 Glass plates 10 x 20 cm 105560 TLC Silica gel 60 RP-18 F254s ( 60 RP-18 F254s硅胶薄层层析板 ) 20 Aluminium sheets 5 x 7.5 cm 105559 TLC Silica gel 60 RP-18 F254s ( RP-18薄层层析板 含荧光指示剂 ) 20 Aluminium sheets 20 x 20 cm 115685 TLC Silica gel 60 RP-18 F254s ( RP-18薄层层析板 含荧光指示剂 ) 25 Glass plates 5 x 10 cm 115389 TLC Silica gel 60 RP-18 F254s ( 薄层层析板 RP-18 含荧光指示剂 ) 25 Glass plates 20 x 20 cm 115683 TLC Silica gel 60 RP-18 F254s ( 薄层层析板 ) 50 Glass plates 5 x 20 cm 115423 TLC Silica gel 60 RP-18 F254s ( 薄层层析板 RP-18 含荧光指示剂 ) 50 Glass plates 10 x 20 cm 胜肽分析平板 At Merck, we’ve enhanced our ProteoChrom® plates to make separation highly efficient – especially when peptides and protein digests need to be analyzed.
