Capillary columns, SE-30 and SE-54

Leverancier: Agilent
Omschrijving: These columns are not bonded or cross-linked, and are therefore useful for established methods that do not require the column to have cross-linked or bonded polymer phases. Because SE series columns are not bonded or cross-linked, solvent rinsing is not recommend.

HPLC-kolommen voor analyse van koolhydraten, Hi-Plex

Leverancier: VARIAN
Omschrijving: Hi-Plex HPLC-kolommen zorgen voor meer efficiëntie, lagere werkdrukken en een langere levensduur van kolommen van monogedispergeerde materialen. Met een reeks ligand tegenionen voor optimale selectiviteit en resolutie en materialen afgestemd op de USP-definities van mediatypen L17, L19, L34 en L58, is de Hi-Plex-reeks ideaal voor isocratische scheiding met water of verdund zuur als het eluent. Dit vereenvoudigt de HPLC-systeemvereisten en er hoeven geen mogelijk gevaarlijke organische oplosmiddelen te worden gebruikt.

Product Image-514-0698

Bottle top vacuum filtration systems

Leverancier: SciLabware
Omschrijving: This filteration system is used for microbiology and preparation of HPLC solvents. It is used with 47 mm Ø membranes.

Shut-off valves, Upchurch Scientific®

Leverancier: UPCHURCH SCIENTIFIC
Omschrijving: Stop a flow stream quickly with these shut-off valves. The bodies are manufactured from either PEEK or ETFE. Both versions feature a PCTFE rotor, making them highly resistant to chemicals. The blue colorant used in some valve configurations has proven not to leach out with common HPLC solvents.

HPLC columns, Pursuit™ UPS2,4

Leverancier: VARIAN
Omschrijving: Pursuit™ UPS 2,4 columns couple highly efficient, fast separations with superior ease-of-use. They are designed for solvent applications and samples where lifetime and back pressure are important concerns.

Product Image-554-0237

HPLC-kolommen voor anionuitwisseling, PRP-X100

Leverancier: HAMILTON BONADUZ
Omschrijving: The PRP-X100 is a polymeric column packing for separation of inorganic and organic anions from 10 to 500 ppm. These columns can be used to separate ions at concentrations from 1 to 1000 ppm without suppression or elaborate preconcentration techniques. The highly inert polymeric support resists chemical attack from organic solvents and aqueous buffers (0 - 100% aqueous or organic; pH 1 to 13), effectively lengthening column life.

8330 calibration mix #1 (7 components)

Catalogus nummer: (REST31450)
Leverancier: Restek
Omschrijving: EPA method 8330 is used to measure explosives residues in water and soil samples, using HPLC with UV detection. Target analytes are nitroaromatic and nitramine explosives and their degradation products. Obtaining pure, neat compounds for Method 8330 reference standards can be very difficult. To ensure the highest quality standards, Restek's Quality Control (QC) lab confirms the identity and purity of mixture components and solvents using one or more of the following techniques: GC-FID, HPLC, GC-ECD, GC-MS, LC-MS, refractive index, and melting point.
UOM: 1 * 1 mL
