Carbomix Phases ph range (-) for Carbomix H-NP and (-9) for the other types of Carbomix phase Analytical and preparative columns General Description Carbomix lines of columns have been specifically designed for high resolution separation of water soluble and partially water soluble organic compounds, including carbohydrates, organic acids, peptides, and small bio organic molecules involved in cell metabolism. These novel packing materials are based on low crosslinked (%, 8% and 0%) polystyrene/divinylbenzene (PS/DVB) particles ( and 0 µm) with surface modification of sulfonic acid (-S H) for Carbomix H-NP resins, followed by chelating of various metal ions, calcium ions (Ca + ) for Carbomix Ca-NP, lead ion (Pb + ) for Carbomix Pb-NP, potassium ion (K + ) for Carbomix K-NP, and sodium ion (Na + ) for Carbomix Na-NP resins (Figure ). Characters of Carbomix Resins Uniform Particle size. The particle size distribution of Carbomix phases is very narrow,.0 ± 0. for µm and 0.0 ± 0. for 0 µm respectively, as shown in Figure. This mono-dispersed particle size distribution guarantees to offer high efficiency and high resolution separations. Figure shows that a Carbomix Ca-NP column provides higher efficiencies for separating monosaccharides as a comparison to other brands. Figure.

The wide range ionic forms of Carbomix phases available allows for most suitable column choices for achieving the best separation for different kinds of sugar molecules, sugar alcohols and other water soluble compounds from different sources (Table ). For instance, arabinose, ribitol and arabitol are difficult to be separated on an H-form phase but well resolved on a Ca-form column; the peaks of xylose, galactose, and mannose on Ca-form www.sepax-tech.com -877-SEPAX-US

Figure shows that hexasaccharide (G6) is well separated from the sample matrix on a % Carbomix Ca-NP column accompanied by two more peaks, heptasaccharide (G7) and octasaccharide (G8); however, on an 8% Carbomix Ca-NP column, not only G7 and G8 peaks cannot be observed, but also G6 peak is hard to be distinguished. Stability. Carbomix HPLC columns are well manufactured with proprietary packing technique to guarantee high stability. Carbomix resins are stable in pure water and other aqueous buffers at elevated temperature. As shown in Figure, the retention time of the acids changed only 0.% after continuously washed with 78 column volumes at for 6 days. Figure.

The low crosslinking property of Carbomix resins allows for proper swell in the mobile, especially at high temperature that is a typical operation for fulfilling most separation tasks. Such swelling effect results in optimized surface area, permeability, capacity, selectivity, and response to changes in ionic strength for separation.

Carbomix resins can be packed into wide range of column dimensions with ID from 7 µm to. mm and the length from cm to 0 cm. Custom columns are also available. Column length and diameter affect resolution and analysis time. The principle for choosing a suitable column is to use only as much resin as needed to achieve the desired separation. As shown in Figure 6, by using a 7.8 00 mm Carbomix Ca-NP column, the analysis time for an orange juice sample is only / of that using a 7.8 00 mm..0 www.sepax-tech.com -877-SEPAX-US

Fructose Injection volume: 0 µl Sample: Sucrose, glucose and fructose (mm/each) The partition process on Carbomix phases is moderated by the counterion (H +, Ca +, Pb +, K + and Na + ) bounded to the surface. Usually, at least two or more mechanism, including Separation Mechanisms size-exclusion, ion-exclusion, ion-exchange, ligandexchange, reversed-phase and normal-phase, are involved. For carbohydrate sample, size-exclusion mechanism is the primary one for oligosaccharides, as shown in Figure. However, ligand-exchange is the primary one for separating monosaccharides, e.g., the separation of α- and β-anomers of glucose on a Ca-form phase. To fulfill the separation of a molasses sample, the first primary mechanism involved is ion-exclusion, which allows inorganic sodium to be eluted near the void volume. And then size-exclusion and ligand-exchange take effect one after the other for oligosaccharides and monosaccharides. Ion-exclusion can still play a role for sugar alcohols and carboxylic acids in the matrix. As to Carbomix-H-form phase for the separation of organic acids, both reversed-phase and ion-exclusion are the primary mechanism. Hydrophobicity and pk a together impact the retention time of a component in the sample. It is due to this property, it has turned Carbomix-H phase into an ideal choice for monitoring changing components in the process of fermentation.
