Product Image-VARICP17985

Gas clean filter

Leverancier: VARIAN
Omschrijving: Schone gassen verkleinen het risico op kolomschade en vergroten de nauwkeurigheid en gevoeligheid. Deze onbreekbare filters met eigen indicatie bieden een hoge gevoeligheid voor zuurstof en vocht en kunnen in een paar seconden zonder gereedschap worden geïnstalleerd.

Solid phase extraction cartridges, Bond Elut™ SAX

Leverancier: VARIAN
Omschrijving: 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.

Solide fase voor de extractie van cartridges, Bond Elut™ SI

Leverancier: VARIAN
Omschrijving: Inheemse silica wordt algemeen beschouwd als het meest polaire SPE sorptiemiddel beschikbaar. Bond Elut™ SI is bijzonder effectief bij het scheiden van verbindingen met een vergelijkbare structuur. De analyten in een niet-polair oplosmiddel toepassen, daarna de polariteit van het oplosmiddel verhogen door de concentratie van een polaire modificator te verhogen, zoals THF of ethylacetaat, zorgt voor doeltreffende scheidingen.

Strong anion exchange HPLC columns, PL-SAX

Leverancier: VARIAN
Omschrijving: These columns are ideal for the anion exchange HPLC separations of proteins and deprotected synthetic oligonucleotides under denaturing conditions.

Solid phase extraction cartridges, Bond Elut™ NH₂

Leverancier: VARIAN
Omschrijving: 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.

Product Image-VARICP9033

High efficiency GC columns

Leverancier: VARIAN
Omschrijving: High efficiency 0,15 and 0,18 mm Int.Ø columns are a simple and cost effective way to increase sample throughput with existing GC or GC/MS instruments.

Analytical HPLC columns, Microsorb™ Si

Leverancier: VARIAN
Omschrijving: Microsorb™ Silica is ideal for the separation of low molecular weight compounds that dissolve in organic solvents. Separations on silica columns depend upon the difference in orientation, type and number of functional groups associated with the compounds in the sample.

Product Image-VARICP7420

Capillary columns, Select FAME

Leverancier: VARIAN
Omschrijving: The Select FAME column is tuned for optimal cis-trans separations of FAMEs, especially C₁₈ isomers.

Image Unavailable-VARICP7406

Capillary columns, CP-Sil 19 CB for pesticides

Leverancier: VARIAN
Omschrijving: Ideal as a confirmation column for reliable results.

Image Unavailable-VARI12113071

Solid phase extraction cartridges, Bond Elut™ C18 EWP

Leverancier: VARIAN
Omschrijving: 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.

Well plate tubes for Bond Elut C18 OH plates

Catalogus nummer: (VARI7551601C)
Leverancier: VARIAN
Omschrijving: VersaPlate™, VersaPlate well plate tubes, C18 OH, 100 mg
UOM: 1 * 96 ST
Product Image-VARICR2111XX

Ferrules for gas chromatography

Leverancier: VARIAN
Omschrijving: Vespel/graphite and precision graphite ferrules for chromatography applications.

Product Image-568-0699

Capillaire kolommen, CP-FFAP CB

Leverancier: VARIAN
Omschrijving: Kolommen voor vrije vetzuren in zuivelproducten.

Solid phase extraction cartridges, Bond Elut™ C8

Leverancier: VARIAN
Omschrijving: 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.

Solid phase extraction cartridges, Bond Elut™ C18 OH

Leverancier: VARIAN
Omschrijving: 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.
