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 176001911BEH 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

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
