13X

Type 13X offers enhanced adsorption properties and the ability to remove impurities too large to be adsorbed by the type A zeolites.

3A

3A is made by ion-exchanging the sodium in type 4A zeolite with potassium. The 3A molecular sieve will exclude most molecules except water, making it very selective.

4A

4A is the sodium form of the type A zeolite molecular sieve and is widely used as a general purpose drying agent. Under certain conditions, it can also be used for removal of ammonia, alcohols, carbon dioxide, H2S and other specific molecules.

5A

5A is the calcium-exchanged form of the type A zeolite molecular sieve and is primarily used for removing carbon dioxide, carbon monoxide, alcohols and other oxygenates, hydrogen sulfide, methyl and ethyl mercaptans, and others.

Activated Alumina

Activated alumina adsorbent is an effective bed-topping layer used as a protective layer, at the inlet of gas-phase molecular sieve beds.

Calcium X

Calcium X (CaX) and Calcium LSX (CaLSX) molecular sieves are the calcium-exchanged forms of the 13X and LSX type zeolites.

Normal Phase Silica phases are suitable for separations of polar and basic organic compounds, such as vitamins, steroids, as well as pharmaceuticals.

Classical Normal Phase – Diol

Normal Phase Silica phases are suitable for separations of polar and basic organic compounds, such as vitamins, steroids, as well as pharmaceuticals.

Classical Normal Phase – NH2

Normal Phase Silica phases are suitable for separations of polar and basic organic compounds, such as vitamins, steroids, as well as pharmaceuticals.

Classical Reversed Phase – C18

ZEOsphere C18 phases are the most preferred as they offer an excellent range of hydrophobic separation power along with high surface area coverage.

Classical Reversed Phase – C4

ZEOsphere C4 is commonly used to separate large macromolecules such as proteins

Classical Reversed Phase – C8

An excellent range of hydrophobic separation power along with high surface area coverage, but when less retention compared to a C18 is needed.

Classical Reversed Phase – CN

Common applications based on Cyano phases include the separation of flavonoids, extraction of polar compounds from non-polar samples as well as analytes with a wide range of hydrophobicity.

Classical Reversed Phase – Phenyl and Derivatives

Classic reversed phase material based on 100Å and 120Å Ultra-pure silica with high surface area. ZEOsphere Phenyl as reverse phase or in HILIC mode shows alternative selectivity to C18 and C8 column

ZEObeads 50 C18 / 20-30µm

Spheroidal shape alkyl-bonded silica used in reversed-phase chromatography, preferably where superior flow performance and selectivity are needed.

ZEObeads 50 C8 / 20-30µm

ZEObeads 50 C8 / 20-30um is a spheroidal shaped silica with a reduced alkyl chain length, slightly less hydrophobic in reverse phase chromatography. The shorter alkyl chain length allows in some cases a better interaction with the target compound.

ZEObeads 50 Diol / 20–30µm

ZEObeads 50 NH2 / 20-30um is a spheroidal shaped amine bonded silica. It is used in normal phase chromatography for target compounds with more alkaline pH and as an excellent metal scavenger under conditions of superior flow performance.

ZEObeads 50 NH2 / 20-30µm

ZEObeads 50 NH2 / 20-30um is a spheroidal shaped amine bonded silica. It is used in normal phase chromatography for target compounds with more alkaline pH and as an excellent metal scavenger under conditions of superior flow performance.
