In-line syringe filters, Nalgene®

Dodavatel: Thermo Fisher Scientific
Popis: These syringe filters with PTFE membrane and PP housing are used for benchtop fermenters, in-line gas filtration for sterile air or CO₂ and to protect vacuum pumps from damage by aqueous solutions. They are also designed for filtration of aggressive chemicals and solvents such as those used in GC and HPLC.

Environmentally Preferable

Capillary columns, SE-30 and SE-54

Katalogové číslo: (HEWL112-5432)
Dodavatel: Agilent
Popis: 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.
Měrná jednotka: 1 * 1 KS

Ion exclusion HPLC columns, PRP-X300

Dodavatel: HAMILTON BONADUZ
Popis: A fast, versatile HPLC column packing material. These columns rapidly and easily separate closely related alcohols and organic acids without column heating. The sulfonated poly(styrene-divinylbenzene) support separates samples by a mixed mode mechanism. A wide range of samples can be analysed with these columns because the selectivity of the column can be altered by changing the pH of the buffer or adding an organic modifier (methanol, acetonitrile) to the buffer. The stability to organic solvents makes it possible to analyse samples that have been too highly retained on conventional ion exclusion supports.

Shut-off valves, Upchurch Scientific®

Dodavatel: UPCHURCH SCIENTIFIC
Popis: 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.

Solid phase extraction cartridges, Bond Elut™ PRS

Dodavatel: VARIAN
Popis: Bond Elut™ PRS is a strong cation exchange sorbent that is also relatively high in polarity. With no appreciable degree of hydrophobicity, in non-polar solvents, PRS is capable of polar and hydrogen bonding interactions. Due to the very low pKa of PRS, a high ionic strength eluent must be used, and so the use of PRS is recommended for weaker cationic species such as pyridinium compounds.

Capillary columns, HP-PLOT Q

Dodavatel: Agilent
Popis: General purpose columns for solvents, sulfur compounds, oxygenated compounds, C1 to C3 isomers, methane, air/CO, and alkanes upto C12. Ideal for ethane, ethylene and ethyne separation.

Empty columns, XK series

Dodavatel: Cytiva
Popis: XK empty columns are designed for liquid chromatography at low to medium pressure. The user friendly design ensures trouble-free operation with fittings for direct connection to high performance liquid chromatography systems. They are compatible with aqueous solutions and most organic solvents used in liquid chromatography of macromolecules. They are not resistant to acetone, ktones, chlorinated hydrocarbons, aliphatic esters and phenol. Should be avoided: >10% NaOH, >10% HCl, >5% acetic acid and strong mineral acids.

QuEChERS extraction products

Dodavatel: Thermo Fisher Scientific
Popis: The QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) technique is increasingly becoming the technique of choice for the extraction of pesticide residues in fruit, vegetables and other foods. The QuEChERS method offers the advantage of high recoveries, accurate results and high sample throughput, combined with the associated cost savings with low solvent and labour requirements. Yet the procedure is robust and rugged.

QuEChERS extraction kits

Dodavatel: Agilent
Popis: Step 1: Extraction
Choose the extraction salt packet based on your method of analysis, AOAC or EN. The buffered extraction salts are amenable for more liable pesticides. Adding solvent and then salts to a comminuted fruit or vegetable sample (10 g or 15 g) enables you to extract the pesticides of interest into the organic layer. However, adding a food sample with a high percentage of water directly to the salts may create an exothermic reaction that can affect your analyte recoveries.
