MP EcoChrom™ Alumina B, Activity I are a good "all-round" adsorbents for laboratory use as well as for industrial use. They can be adjusted to lower activity by the addition of polar media, preferably water, but also higher alcohols, e.g. glycol or glycerol can be used. An oxide of aluminum, occurring in nature as various minerals such as bauxite, corundum, etc. It is used as an adsorbent, desiccating agent, and catalyst, and in the manufacture of dental cements and refractories.

MP EcoChrom™ Silica is an oxide of silicon. Their sieve cuts are optimized according to the sieve range of the German Industrial Standard (DIN). The irregular shape of this product permits easy packing of columns of different sizes and optimization of column permeability and plate number. They allow easy switching from one sieve cut to another, offering an easy way to change the chromatographic methods.

MP EcoChrom™ Silica, the chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with the chemical formula SiO2 with a mean pore size of 60Å and particles size of 100-200μm. MP silica are free of particles outside the standard range. The irregular shape of MP Silica permits the easy packing of column permeability and plate number. They allow easy switching from one sieve cut to another, offering an easy way to change the chromatographic methods. It has been known for its hardness since ancient times. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms.

Mean Pore Size: 60Å

In addition to the convential silica, MP Biomedicals produce active silica. These MP EcoChrom™ Silica, active, exhibit a well defined high inital activity in addition to the good properties of MP EcoChrom™ Silica. The initial activity of MP EcoChrom™ Silica, active, corresponds to the activity of Alumina activity I.

MP EcoChrom™ Silica, GF-TLC, contains fluorescent indicator F254 and gypsum. They are produced from the same highly standardized raw material as the MP EcoChrom™ Silica for column chromatography. They are available with or without binder and with or without fluorescent indicators.

MP EcoChrom™ Silica, the chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with the chemical formula SiO2 with a mean pore size of 60Å and particles size of 63-200μm. MP silica are free of particles outside the standard range. The irregular shape of MP Silica permits the easy packing of column permeability and plate number. They allow easy switching from one sieve cut to another, offering an easy way to change the chromatographic methods. It has been known for its hardness since ancient times. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms.

MP EcoChrom™ Silica is an oxide of silicon.

MP EcoChrom™ Silica-Plates cover a wide range of Thin-Layer Chromatography applications: qualitative and quantitative separations as well as semi-preparations. Their uniform surface makes MP EcoChrom™ Silica-Plates suitable for quantitative densitometric UV/VIS evaluation. MP EcoChrom™ Silica-Plates are prepared with an organic binder, inert to all solvents and reagents usually applied in TLC.
