Proveedor: VARIAN
Descripción: PL-Guanidine MP SPE, flangeless, 500 mg/6 ml

Proveedor: VARIAN
Descripción: PLgel Olexis is optimized for the analysis of high molecular weight polymers at elevated temperatures, particularly polyolefins and high performance polymers.

Proveedor: VARIAN
Descripción: These rigid, strong ion exchange materials are extremely hydrophilic that is ideal for purification of biomolecules. The PL-SAX and PL-SCX materials are totally polymeric and are chemically and thermally stable over a full range of HPLC conditions.

Proveedor: VARIAN
Descripción: Bond Elut™ SAX is a strong anion exchange sorbent ideally suited for the extraction of compounds such as carboxylic acids, which may not retain effectively on weak anion exchange sorbents. The sorbent is supplied in the chloride counter ion form. You can modify the selectivity of the phase by replacing the chloride ion with other anions, such as acetate and hydroxide.

Proveedor: VARIAN
Descripción: Bond Elut™ C8 is very similar in properties to C18, but is not as retentive for non-polar compounds, due to its shorter hydrocarbon chain, and therefore reduced carbon loading. C8 is an excellent replacement for C18 when analytes are too strongly retained for effective elution. The potential for polar interactions is somewhat higher than for C18 because there is less coverage of the silica surface. These polar interactions are not, however, a significant property of C8.

Descripción: The MetaCarb™ line of carbohydrate columns provides high resolution columns for applications requiring high performance carbohydrate and organic acid analysis. These columns contain sulfonated polystyrene resins in the Calcium (87C), Hydrogen (87H), and Lead (87P) forms, and provide a wide range of selectivities for carbohydrate and organic analysis. They are widely used in the food and beverage industries for analysis of sweeteners, corn and cane sugars, fruit juices, soft drinks, beer and dairy products.

Descripción: Native silica is generally regarded as the most polar SPE sorbent available. Bond Elut™ SI is particularly effective at separating compounds with a very similar structure. Applying the analytes in a non-polar solvent, then increasing the solvent polarity by increasing the concentration of a polar modifier, such as THF or ethyl acetate, delivers effective separations.

Proveedor: VARIAN
Descripción: MonoChrom® columns provide excellent chromatography of organic amines, organic acids, amphoteric compounds and neutral compounds.
UOM: 1 * 1 UN


Proveedor: VARIAN
Descripción: Bond Elut™ C18 OH is a non-end capped version of the octadecyl bonded phases that enables the silanols on the silica surface to be more active. This low-load C18 has well-controlled silanol activity that permits the fractionation of metabolites and enhances retention of basic compounds compared to an endcapped C18. The pore size makes it a good choice for peptide extraction.

Proveedor: VARIAN
Descripción: Bond Elut™ NH₂ is a weaker anion exchanger than sorbents such as SAX (a quaternary amine sorbent that is always charged) and is therefore a better choice for retention of very strong anions, such as sulfonic acids, which may retain irreversibly on a SAX sorbent. Similar to Diol and SI sorbents, Bond Elut™ NH₂ is excellent for the separation of structural isomers.

Proveedor: VARIAN
Descripción: Bond Elut™ EWP is based upon standard particle size silica but with 500 Å pores to allow more efficient extraction of large molecules (>15000 MW), which are typically excluded from standard porosity silica phases.

Numero del catalogo: (VARI7541201C)
Proveedor: VARIAN
Descripción: Unique bond Elut PBA silica sorbent uses phenylboronic acid functionality to retain analytes via a reversible covalent bond, with high specificity and cleanliness.
UOM: 1 * 1 UN


Proveedor: VARIAN
Descripción: Vespel/graphite and precision graphite ferrules for chromatography applications.

Proveedor: VARIAN
Descripción: Columns for free fatty acids in dairy products.

Numero del catalogo: (VARICP7520)
Proveedor: VARIAN
Descripción: CP-Squalane gives the best separation of C₄-C₁₀ hydrocarbons.
UOM: 1 * 1 UN


Numero del catalogo: (VARICP7527)
Proveedor: VARIAN
Descripción: CP-Carbowax 400 has highest resolution for amyl alcohols for accurate quality inspection.
UOM: 1 * 1 UN
