With this technique, it is also possible to separate and detect select carbohydrates simultaneously with amino acids in a single run. For applications where carbohydrates are present, but only the amino acids are of interest, the CRC can be installed to remove the carbohydrates on-line.The CRC is an in-line pretreatment cartridge packed with cation-exchange resin. The amino acids are retained and the carbohydrates are washed to waste. After the carbohydrates have been removed from the cartridge, the CRC is switched in-line with the AAA-Direct system and the AminoPac® PA10 column separates the amino acids.The CRC is used in conjunction with the carbohydrate removal accessory (CRA). In addition to the CRC, the CRA consists of a syringe pump and six-port valve. To install the CRA, the AAA-Direct system must be modified. The syringe pump is connected to the autosampler, whereas the GS50 pump and AminoPac PA 10 are redirected to the six-port switching valve.Comparison of Chromatograms with and without the SugarTrap Installed.Ordering InformationCarbohydrate Removal Accessory Kit for ICS-3/5000 DP064418Carbohydrate Removal Accessory Kit for ICS-3/5000 SP070510Carbohydrate Removal Cartridge (CRC) for AAA-Direct0685982nd Channel Kit, LC20/30, Right Slide, Rear Loading052322Acclaim SST Guard Cartridge Holder V-1059456

碳水化合物分析使用HILIC色谱分离的最多也是最广泛的化合物之一就是碳水化合物，例如：单糖、二糖、寡糖，和多糖。ACQUITY UPLC BEH Amide柱是用于分析碳水化合物的优异工具，提供以下优势：1、1.7μm 粒径使得高分辨、高速的分析复杂样品基质中的碳水化合物，同时仍维持甚至提高色谱分离度2、更强的化学稳定性，允许使用高 pH和高温条件以合并还原性糖差向异构体的岔头峰，使定量更准确，缩短分析时间，并提高MS响应。3、BEH 颗粒技术，以及三键键合式的酰胺基(Amide)键合相技术，提供了优异的色谱柱寿命，也增强了分析方法的耐用性4、与常规用于碳水化合物分析的氨基柱( NH 2 )不同，ACQUITY UPLC BEHAmide柱不易生成Schiff碱，从而改善定量准确性。5、与高 pH流动相的兼容性，有助于MS检测而无需衍生化、柱后添加剂、或与金属阳离子络合，从而极大简化了LC/MS分析前的样品预处理工作，并提高分析灵敏度。使用UPLC/MS分析糖固定相 粒径 规格 部件号1/pk 部件号3/pkBEH Amide 1.7 μm 1.0 x 50 mm 186004848 176001914BEH Amide 1.7 μm 1.0 x 100 mm 186004849 176001915BEH Amide 1.7 μm 1.0 x 150 mm 186004850 176001916BEH Amide 1.7 μm 2.1 x 30 mm 186004839 176001906BEH Amide 1.7 μm 2.1 x 50 mm 186004800 176001907BEH Amide 1.7 μm 2.1 x 75 mm 186005657 —BEH Amide 1.7 μm 2.1 x 100 mm 186004801 176001908BEH Amide 1.7 μm 2.1 x 150 mm 186004802 176001909BEH Amide 1.7 μm 3.0 x 30 mm 186004803 176001910BEH Amide 1.7 μm 3.0 x 50 mm 186004804 176001911 BEH Amide 1.7 μm 3.0 x 75 mm 186005658 —BEH Amide 1.7 μm 3.0 x 100 mm 186004805 176001912BEH Amide 1.7 μm 3.0 x 150 mm 186004806 176001913
