Provide an economical alternative to glass for some applications with Thermo Scientific? 9mm Plastic Screw Thread Vials. They are manufactured from high-quality, GC-tested polypropylene material. Polypropylene vials are chemically inert and suitable for most chromatography applications. Where levels of inorganic ions have to be kept to an absolute minimum the use of plastics may be preferred to the more conventional glass vials. Choose from Thermo Scientific?, Thermo Scientific? National?, and Thermo Scientific? Chromacol? brands.

使用高靈敏度檢測功能進(jìn)行表面活性劑分析時，首選色譜柱是 Thermo Scientific? Acclaim? Surfactant Plus LC 色譜柱。這種新一代高效率硅膠基色譜柱的特點(diǎn)是流失率超低，可與帶電氣溶膠檢測器（CAD）和質(zhì)譜儀（MS）配合使用。這類色譜柱的選擇性與 Acclaim Surfactant 色譜柱相似，可靈敏分離各種表面活性劑。其先進(jìn)的表面化學(xué)鍵合可同時提供反相機(jī)制和陰離子交換保留機(jī)制，從而顯著提高表面活性劑的分離度。

用 Thermo Scientific? Acclaim? Surfactant LC 色譜柱實(shí)現(xiàn)各類表面活性劑的分離，效果卓越。 這些硅膠基質(zhì)的高效色譜柱為使用 UV-Vis、蒸發(fā)光散射檢測器 (ELSD) 或折射率 (RI) 檢測器的 HPLC 分離提供卓越的分離度和通量。 獨(dú)特的表面化學(xué)鍵合技術(shù)提供了獨(dú)特的極性，相比傳統(tǒng)的 C18 色譜柱，它優(yōu)化了乙氧基表面活性劑中單低聚物的分離度。

For optimizing separations of hydrophobic and halogenated anions, use the Thermo Scientific? OmniPac??PAX-100 Column. This polymer-based anion-exchange column is solvent compatible and stable over the entire pH range of 1-14. Solvents may be used to affect selectivity, solubilize otherwise insoluble samples, and to remove contaminants to prolong column lifetime. The OmniPac PAX-100 column is particularly well suited for the analysis of larger organic acids, including alkylbenzene sulfonates, aromatic acids, barbiturates, polyphosphates, inositol phosphates, thiocyanate, thiosulfate, and iodate.

When you need to separate anionic and neutral species in a single run, use the Thermo Scientific? OmniPac??PAX-500 Column. With anion-exchange and reversed-phase properties, this polymer-based mixed-mode column is solvent compatible and stable over the entire pH range of 1-14. Solvents may be used to affect selectivity as well as to remove contaminants to extend column lifetime. The OmniPac PAX-500 column is ideal for analysis of a wide range of compounds.

Separate cationic and neutral analytes in a single run by using Thermo Scientific? OmniPac??PCX-500 Columns. With cation-exchange and reversed-phase properties, this polymer-based mixed-mode column is solvent compatible and stable over the entire pH range of 1-14. Solvents may be used to affect selectivity as well as to remove contaminants to extend column lifetime.

Separate hydrophobic cations using the solvent-compatible cation-exchange Thermo Scientific? OmniPac??PCX-100 Column. This polymer-based cation-exchange column is solvent compatible and stable over the entire pH range of 1-14. Solvents may be used to affect selectivity, solubilize otherwise insoluble samples, and to remove contaminants to prolong column lifetime. The OmniPac PCX-100 column is particularly well suited for the analysis of hydrophobic cationic analytes including amines, anilines, antidepressants, drugs, and metabolites (such as methotrexate and folic acid).
