Both supports are designed to resolve full length from n–1, n+1, and other failure sequences not possible with other columns. Retention times and selectivity can be controlled by choice of salt, pH, and solvent. Therefore, the separation can be tailored to the requirements of many different oligonucleotide analysis challenges. Achieve n, n-1 resolution for oligonucleotides.Resolve oligonuleotide linkage and stereoisomers.Assay phosphorothioate purity.Attain selectivity control with eluent pH, salt, and solvent.Resolve RNA with aberrant (2’–5’) links from normal SSRNA.The DNAPac PA200 is packed with a pellicular anion-exchange resin composed of an 8 μm diameter nonporous polymeric substrate to which quaternary amine-functionalized Thermo Scientific™ Dionex™ MicroBeads™ are bound. The rapid mass transport characteristics of this resin result in high-resolution oligonucleotide separations. The DNAPac PA200 RS is smaller, with 4 μm diameter resin for bio-UHPLC separations. These rapid separation (RS) columns are designed for use with the Thermo Scientific™ Dionex™ UltiMate™ 3000 BioRS system, with an operational backpressure limit of 10,000 psi. Columns packed with smaller particles improve resolution and offer better performance.The DNAPac PA200 and PA 200 RS can be operated under denaturing conditions, such as high temperature (up to 85 °C), high-pH eluents (up to pH 12.5), or by the inclusion of chaotropic agents (such as Urea).These columns offer the highest-quality phase stability over a broad pH range, deliver exceptional resolution, and support high-throughput separations. DNAPac PA200 and PA 200 RS columns support resolution of normal-length oligonucleotides (8- to 30- mer), extended-length oligonucleotides (30- to 70-mer), linear double-stranded DNA, and supercoiled versus nicked/linear DNA.Analytical separations on the DNAPac PA200, 8μm, 4 mm diameter column can be scaled directly to larger diameter columns so preparative methods can be conveniently developed using small samples. Scaling the flow rate and sample size up for the 9 × 250 mm and 22 × 250 mm column yields essentially identical chromatography.Column SpecificationsDNAPac PA 200DNAPac PA 200 RSColumn Chemistry55% crosslinked nonporous polymer with Quaternary amine functionalized latex MicroBeadsParticle Size8 μm4 μmIon Exchange Capacity~ 14 μeq/mL~ 20 μeq/mLpH Range4 to 10 (12.5 with salt, see manual)Pressure Maximum4,000 psi10,000 psiTemperature rangeRecommended operating temperature: Controlled ambient Temperature limit: 85 °CFlow RatesRecommend 0.1 to 1.5 mL/minOrganic Solvent Limit100% acetonitrile or methanol for cleaningTypical EluentsHigh purity water (18 megohm-cm), sodium chloride, sodium perchlorate, buffers, sodium acetate and sodium hydroxide.Detergent CompatibilityCompatible with nonioinic, cationic or zwitterionic detergents.Resolution of oligonucleotides using DNAPac PA200 column (8μm).

Dionex AminoPac PA1 氨基酸分析柱用途和特点AminoPac PA1柱用于氨基酸的快速分离。特别适用于分析酸性和酸不稳定性氨基酸，以及用阳离子交换分离不完全的氨基酸对。Dionex AminoPac PA1 氨基酸分析柱订货信息：分析柱AminoPac PA1 Analytical Column (4 x 250 mm)037022保护柱AminoPac PA1 Guard Column (4 x 50 mm)037023For Specialized Amino Acid Applications with Postcolumn DerivatizationThe AminoPac PA1 column is a high-speed, pellicular, strong, anion-exchange column. The PA1 delivers high-efficiency separations as a result of its nonporous-core particle. Its strong anion-exchange characteristics are imparted by agglomerating surface MicroBead™ particles that are functionalized with the quaternary ammonium functional group, resulting in a higher capacity than typically offered by nonporous resins.Resolves phosphorylated and other amino acids by anion-exchange chromatographySeparates acid-labile amino acids under basic pH conditionsSeparates strongly acidic amino acidsRequires OPA or ninhydrin postcolumn derivatizationThe anion-exchange selectivity of the AminoPac PA1 can be used to resolve peaks that cannot be resolved using a cation-exchange column. For example, O-phosphorylated amino acids are resolved and eluted near the end of a hydrolysate chromatogram. Arogenic acid, a precursor to tyrosine and phenylalanine, decomposes under the acidic conditions required for cation-exchange separation or PITC derivatization, but it is stable in alkaline eluents used with AminoPac PA1 column.The PA1 is particularly well suited for acidic and acid-labile amino acids and for amino acid pairs not completely resolved by cation-exchange chromatography.

CarboPac? PA10 column line has been expanded to include a new 0.4 × 250 mm capillary column. As with all CarboPac PA10 columns, the new capillary format is the ideal choice for mono- and disaccharides in foods, drugs and plants.The CarboPac PA10 is an ideal choice for separations of mono- and disaccharides found in mammalian glycoproteins. Fucose is well resolved from the system void and from protein hydrolysate interferents. The CarboPac PA10 allows oxygen to elute after mannose, eliminating interference with monosaccharides. It is ideal for the analysis of mono- and disaccharides in foods, drugs, and plants, and separates sialic acids with the addition of sodium acetate to the eluent.For the quantification of acidic, neutral, and aminomonosaccharidesSimple, isocratic separationsSuperior selectivity for common monosaccharides compared to the CarboPac PA1No derivatization requiredGradient compatibleThe CarboPac PA10 is an anion-exchange column designed specifically for high-resolution separations of mono- and disaccharides.

PA100 is a high-resolution anion-exchange column that provides single-base resolution. It is stable under denaturing conditions, rugged, reliable, and can be readily scaled up. The DNAPac PA100 is a 13 μm pellicular, nonporous polymeric resin with bound quaternary amine-functionalized MicroBeads?. The rapid mass-transport characteristics of this resin result in very high-resolution oligonucleotide separations.Capable of n, n-1 resolution for oligonucleotidesResolves oligonucleotides with secondary structuresCompatible with solvent, high pH, and high temperaturesAnalyzes phosphorothioate-based clinical samplesProvides easy scale-upThe MicroBead resin used in DNAPac columns provides high-resolution separations to ensure maximum peak purity, and makes linear scale-up of your separation easy. For more complex separations, the polymeric properties of the DNAPac PA100 allows great flexibility to select ideal conditions, including high pH, high temperature, or chaotropic agents.Synthetic oligonucleotides can be screened for production yield and failure sequences using the DNAPac PA100. Unit-base resolution of synthetic oligonucleotides to 60 bases and beyond has been demonstrated. The DNAPac PA100 can even be operated under denaturing conditions. Either high temperature (up to 90 °C) or high-pH eluents (up to pH 12.5) can be used to eliminate hydrogen bonding, allowing resolution of problem sequences such as self-complementary sequences or poly-G stretches.Separates RNA / Double-Stranded DNAThe DNAPac PA100 is ideally suited for the purification and analysis of synthetic RNA. Failure sequences are easily separated from the full-length product. Double-stranded DNA, such as plasmids, or restriction fragments are also separated.Analytical separations on the 4 mm diameter column can be scaled directly to larger diameter columns so preparative methods can be conveniently developed using small samples. The loading capacity of the DNAPac PA100 (4 × 250 mm) column is from 1 to 100 μg.
