  • 锂型氨基酸专用分析柱
    两年前的三聚氰胺事件让家长们仍心有余悸,近日"皮革奶"的消息又让人“谈奶色变”。 皮革水解蛋白是从动物皮毛中水解出来的物质,能增加食品中氨基酸的含量,但皮革水解物含有危害人体健康的重金属六价铬。不能用于食品加工,如果被人体吸收的话,可能导致中毒,关节肿大,关节疏松肿大。专家称长期食用“皮革奶”可能致癌。国家卫生部最新印发了《食品中可能违法添加的非食用物质名单(第二批)》,明令禁止在乳及乳制品中添加皮革水解蛋白。皮革水解蛋白与三聚氰胺不同,是正的蛋白质,弱添加到食品中,则检测起来难度更大。 针对这个事件,岛津的分析专家发布了皮革奶的分析解决方案。岛津-GL也将为用户提供锂型氨基酸专用分析柱:Shim-Pack AMINO-Li(6.0mmID×100mmL) 锂型捕氨柱Shim-Pack ISC-30 Li(4.0mmID×50mmL) 。

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.

    Dionex AminoPac PA10 氨基酸分析柱用途和特点AminoPac PA10柱结合阴离子交换,梯度淋洗以及脉冲电化学检测,可以分离多种氨基酸。分离氨基酸的同时,还可检测氨基糖及碳水化合物。此外,还可分离多种糖类,磷酸化氨基酸,以及含硫氨基酸的普通氧化产物,如磺基丙氨酸。其柱填料为疏水性高聚物薄壳型阴离子交换剂,可在pH0-14范围内使用。填料独特的pH稳定性允许使用的淋洗液,有助于氨基酸在金电极的阳极氧化。Dionex AminoPac PA10 氨基酸分析柱订货信息:分析柱AminoPac PA10 Analytical Column (2 x 250 mm)055406AminoPac PA10 (22 x 250 mm)SP5488AminoPac PA10 (9 x 250 mm)SP5490AminoPac PA10 Analytical Column (4 x 250 mm)SP5678保护柱AminoPac PA10 Guard Column (2 x 50 mm)055407AminoPac PA10 Guard Column (4 x 50 mm)SP5680配件AAA-Direct Installation Kit059539Carbohydrate Removal Cartridge (CRC) for AAA-Direct068598For High-Resolution Separations of Free Amino Acids by AAA-DirectThe AminoPac® PA10 column is packed with a hydrophobic, polymeric, pellicular, anion-exchange resin that is stable over the range of pH 0–14. The unique pH stability allows the use of eluents that are conducive to anodic oxidation of amino acids at gold electrodes. This column is recommended for use with the AAA-Direct™ Amino Acid Analyzer, allowing direct detection of primary and secondary amino acids by IPAD, with no need for pre- or postcolumn derivatization.Derivatization not requiredCarbohydrates and amino acids separated and detected simultaneouslyMid-femtomole to low-picomole detection limitsCompatible with all commonly used hydrolysis proceduresCan be configured for on-line analysisAAA-Direct is a technique that eliminates the need for any form of derivatization, and is therefore compatible with on-line monitoring of cell cultures and fermentation broths. The AminoPac PA10 column is optimized for separations of free amino acids by AAA-Direct. Vitamins, amino sugars, and carbohydrates can be detected simultaneously with amino acids. Additional capabilities include separation of a wide range of sugars, phosphorylated amino acids, and common oxidation products of sulfur-containing amino acids, such as cysteic acid, methionine sulfone, and methionine sulfoxide.
