The sorbents used on these plates are carefully standardized and controlled. Each is characterized by narrow particle size and pore volume distribution, standardized surface area and activity, high resolution and capacity. Pre-coated products are stable and economical. Feature uniform, hard, abrasion-resistant coating.
The numbers and abbreviations in column 1 of the price table are defined as follows: a). F254 is a fluorescent indicator with a 254nm excitation wavelength. b). F254+366 is a fluorescent indicator with 254nm and 366nm excitation wavelengths. c). F254s is an acid-stable fluorescent indicator with a 254nm excitation wavelength. d). RP-18 is reversed phase C18 (with an octadecylsilyl chain). e). W is for water tolerant, wettable layer.
