Popis: CP-Wax 57 CB for Glycols and Alcohols is guaranteed for the analysis of glycols, diols and alcohols. It has a unique, high polarity wax phase that produces symmetrical peaks.

Dodavatel: VARIAN

Popis: CP-Sil 5/C₁₈ CB for PCB has a lower polarity than 100% polydimethylsiloxane due to its C₁₈ substitutions. Due to the absence of cyano groups it provides high signal-to-noise ratios for ECD detectors.

Popis: The CP-Si™l line consists of a range of stationary phases which are based on a polysiloxane backbone. Functional groups are added to the polymer to introduce selectivity. Each polymer used for the CP-Sil line is manufactured in-house and is optimised to obtain highest degree of reproducibility.

Popis: The 700 series syringe is the original hand-fitted Hamilton syringe. This series of syringes is ideal for dispensing volumes from 0,5 to 500 µl. The stainless steel plunger is manufactured to fit the glass barrel with a tolerance smaller than 100 millionths of an inch, resulting in unsurpassed syringe life. Each syringe is manufactured to achieve the highest level of accuracy and precision possible.

Popis: Silphenylene-based stationary phase (selectivity equivalent to 5MS columns) to ensure minimum bleeding level at high temperatures. General purpose low polarity phase for a wide range of applications, including (for example): PCBs, essential oils, pesticides, semi-volatiles and many more. HI-5 MS Xil is an MS grade low bleeding cross-bonded column that ensures a long lifetime even under high temperature limits.

Popis: CP-Wax for volatile amines and diamines is optimised for analysis of volatile amines and diamines, particularly C3-C8 amines and diamines. The column delivers symmetrical peaks due to basic reagent deactivation and exhibits good inertness towards basic compounds.

Dodavatel: VARIAN

Popis: The VF-5ht improves the analysis of high boiling compounds by exhibiting low bleed, even at high temperatures. Based on ultra-low bleed FactorFour technology, VF-5ht provides unmatched selectivity, sensitivity, and accuracy for the analysis of high-molecular weight compounds.

Dodavatel: VARIAN

Popis: CP-Sil 5 CB for Formaldehyde is optimized for the analysis of formaldehyde, water and methanol, and can deliver trace analysis of sulfur compounds and partial permanent gases.

Dodavatel: Thermo Fisher Scientific

Popis: These columns are custom-tailored to analyse dioxins and polychlorinated biphenyls (PCBs). Optimised to meet the requirements of high-resolution GC/MS methods, these columns deliver optimum performance with exceptional stability and very low bleed. These low-polarity columns provide wide coverage of the 17 cogeners with the highest toxicological significance (2,3,7,8-chlorine substituted congeners).

Popis: These columns allow chromatographers to employ essentially any organic solvent as mobile phase to develop methods for the most challenging separations. These columns are available in a variety of particle sizes and offer great speed and column resolving power. Columns packed with 3 µm CSPs offer high speed separations and a reduction in analysis time and cost per sample. Columns, packed with 3 µm particles, may be used in conventional HPLC units without significant loss in performance, even with the smaller column dimensions.

Popis: These headspace syringes feature a unique Glue-Free (GF) needle attachment in combination with a High Dynamic (HD) plunger. They are designed specifically for PAL COMBI–xt® headspace autosamplers. Conventional headspace syringe needles are attached to the syringe glass body using glue (cement). Common problems are detached needles or ghost peaks due to low chemical inertness of the cement to solvents or limited resistance to higher temperature. These problems are addressed with the Glue Free High Temperature (HDHT) headspace syringes.

Popis: CP-Al₂O₃/Na₂SO₄ is an aluminum oxide PLOT column that offers high selectivity for separating ppm levels of C₁to C₅ hydrocarbons in a main stream of C₁ to C₅ hydrocarbons. The Na₂SO₄ deactivation salt provides a polar Al₂O₃ surface, so that unsaturated compounds such as ethylene and acetylene are retained longer. These columns analyse more compounds in a single run than packed columns, while still delivering higher resolution and faster analysis times. When compared to liquid stationary phases, CP-Al₂O₃ provides increased selectivity and allows all C₁ to C₅ hydrocarbon isomers to be separated. CP-Al₂O₃ operates without the need for sub-ambient cooling.
