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.

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.

PA1 is an anion-exchange column for the separation of mono-, disaccharides, and specific oligosaccharides using an isocratic eluent. Sialic acid analysis has also been demonstrated on this column. General-purpose column for isocratic determination of monosaccharides and disaccharidesDetection by pulsed amperometric detection no derivatization neededApproved for use in a variety of official methods for the analysis of foodsThe unique MicroBead? pellicular structure of the CarboPac PA1 resin gives it stability from pH 0–14 at all concentrations of buffer salts. The pellicular resin structure allows excellent mass transfer resulting in fast gradient reequilibration.The CarboPac PA1 column is used with pulsed amperometric detection no derivatization is required. Sensitivity on the PA1 is not as high as with the CarboPac PA20 or PA10 for monosaccharide analysis. Thus the CarboPac PA1 is well suited for the analysis of foods for nutritional labeling. The CarboPac PA1 has been approved for use in a number of official methods.

丙酸倍氯米松混悬液分散机，倍氯米松分散机，丙酸氟替卡松雾化吸入用混悬液分散机，进口丙酸倍氯米松混悬液分散机，上海丙酸倍氯米松混悬液分散机生产厂家 混悬液 分散是至少两种互不相溶或者难以相溶且不发生化学反应的物质的混合过程。工业分散的目标是在连续相中实现“令人满意的”精细分布。 当固体颗粒分散到一种液体中时，形成一种悬浮液。当一种液体分散到另一种液体中时，形成一种乳浊液。在一种乳浊液的两个液相间的界面处，表面张力开始发生作用。新表面的产生需要能量。在没有外部影响的情况下，每个液相体系均企图以较少的能量达到乳浊液状态。因此，总是会有产生较小界面的倾向，这阻碍任何乳浊液的形成。 为了实现互不相溶相的分散，必须强力粉碎并混合其粒子。粉碎意味着必须克服表面张力的阻力来形成新表面。分散过程传递所需的能量，并保证两相均质混合。分散的长期稳定性会受到确切粒度分布及乳化剂和稳定剂使用的影响。 现在分散机的应用不仅仅局限于“分散”，由于其独特的剪切作用，对粉粒体在液体中的粉碎撞击终细化到理想的粒径，从而使固体质充分掺混到液体中并形成相对稳定的悬浮液，这种过程也就是“分散”。当然与乳化剂一样，添加了分散剂后，悬浮液的稳定性就能得到增强。当某种固体物质通过一定时间与液体的接触能够被液体彻底溶解，那么经剪切撞击而形成的小颗料将更快地被液体所溶解，因为其比表面积增大了好多倍了。从设备角度分析影响分散乳化效果的因素：1、分散机的结构。分散机一般分为间歇式分散机和管线式分散机，管线式分散机分散效果更好，物料可以充分分散乳化，效率高。IKN高剪切分散机采用的是管线式的分散乳化方式。2、分散机的剪切速率。分散设备核心参数就是剪切速率，一般情况下，剪切速率越高，分散乳化效果越好，当然也需要根据具体物料工艺来定；IKN分散机通过皮带加速，转速达9000rpm，是普通分散机转速的3倍，高转速可达21,000rpm。3、处理时间。物料在腔体里面停留时间越长，相对应的分散乳化效果越好，处理次数越多，一般来说分散乳化效果越好。IKN分散机结构设计采用的是立式分体结构，运行时间短。 4、分散头的加工精度。传统分散乳化机采用单层分散乳化头，加工粗糙，而IKN纳米分散乳化机采用三分散乳化头，间隙更小，精密程度更高，分散乳化效果也会更好。设备的选型要点：1、明确使用设备所需达到的效果和目的2、详细了解并掌握研究物料的性质（包括物理、化学性质）3、根据物料对设备的搅拌机进行选型4、再次确定设备的操作参数及结构设计5、综合考虑设备的成本 上海依肯自主研发生产的分体式三分散乳化机，具有高转速、低能耗、低噪音、高寿命等优势，市场上正常用的分散乳化机由于定转子精度以及机械密封的原因，转速高只能达到2910转，而如此低转速以及跟不上市场上对物料分散乳化均质效果 的高要求。IKN特别研立式分体式分散乳化机解决了此难题，将转速提高到了9000转，外加变频器，高可21000rpm，成功解决了市场需求...更多详情请致电上海依肯机械设备有限公司 销售工程师 徐工 182-0189-1183，公司有样机可以免费实验。丙酸倍氯米松混悬液分散机，倍氯米松分散机，丙酸氟替卡松雾化吸入用混悬液分散机，进口丙酸倍氯米松混悬液分散机，上海丙酸倍氯米松混悬液分散机生产厂家
