BioBasic18色谱柱对中小肽具有杰出的分离效果.300?的孔径，分离生物大分子柱效很高.峰容量极高，可作为二维色谱固定相.极好的重复性、极高的柱效、极长的柱寿命.LC/MS应用的理想选择BioBasic18反相色谱柱是专为分子量小于5000Da的中低疏水性小肽而设计。300?的孔径，高纯度硅胶和稳定的键合相使BioBasic填料成为LC/MS、二维色谱和生命科学应用的理想选择。一般来说，蛋白质的保留属于吸附/解吸机理。即蛋白质疏水性部分可逆吸附在色谱柱头的键合相上。当流动相条件变化，一般是增加有机溶剂的浓度，蛋白质解吸附而被洗脱下来。对于体积比较大的蛋白质来说，填料孔径的选择也很重要，因为大部分的键合相位于空内部，所以所选择的孔径必须足够容纳被分析物。从胰蛋白酶消化液分离谱图可以看出，对于分子量较大的蛋白质，选择300?孔径的BioBasic色谱柱的分离效果好于150?的C18色谱柱。BioBasic色谱柱具有杰出的柱效与重复性。极高密度的键合相和最新的表面去活技术，使BioBasic反相固定相表现出优异的稳定性、重复性和尖锐的峰形，从而保证结果的可靠性。通常分析蛋白质、多肽可以选择不锈钢型BioBasic反相色谱柱。但是如果样品需要回收或者测量金属浓度时，不锈钢柱不适用，可以选用PEEK柱。若您需要进一步了解生物样品分离和BioBasic色谱柱，请参考《生物大分子高效液相色谱分析技术指南TG20026》。 BioBasic18（5 m）反相色谱柱订货信息 4.6mm4.0mm3.0mm2.1mm1.0mm30mm72105-03463072105-03403072105-03303072105-03213072105-03103050mm72105-05463072105-05403072105-05303072105-05213072105-051030100mm72105-10463072105-10403072105-10303072105-10213072105-101030150mm72105-15463072105-15403072105-15303072105-15213072105-151030250mm72105-25463072105-25403072105-25303072105-25213072105-251030BioBasic4（5 m）色谱柱订货信息 4.6mm4.0mmID3.0mm2.1mm1.0mm50mm72305-05463072305-05403072305-05303072305-05213072305-051030100mm72305-10463072305-10403072305-10303072305-010213072305-101030150mm72305-15463072305-15403072305-15303072305-15213072305-151030250mm72305-25463072305-25403072305-25303072305-25213072305-251030BioBasic8（5 m）色谱柱订货信息 4.6mm4.0mm3.0mm2.1mm1.0mm50mm72205-05463072205-05403072205-05303072205-05213072205-051030100mm72205-10463072205-10403072205-10303072205-10213072205-101030150mm72205-15463072205-15403072205-15303072205-15213072205-151030250mm72205-25463072205-25403072205-25303072205-25213072205-251030BioBasicAX（5 m）阴离子交换色谱柱 4.6mm4.0mm3.0mm2.1mm1.0mm50mm73105-05463073105-05403073105-05303073105-05213073105-051030100mm73105-10463073105-10403073105-10303073105-10213073105-101030150mm73105-15463073105-15403073105-15303073105-15213073105-151030250mm73105-25463073105-25403073105-25303073105-25213073105-251030BioBasicCN（5 m）色谱柱订货信息 4.6mm4.0mm3.0mm2.1mm1.0mm50mm72905-05463072905-05403072905-05303072905-05213072905-051030100mm72905-10463072905-10403072905-10303072905-10213072905-101030150mm72905-15463072905-15403072905-15303072905-15213072905-151030250mm72905-25463072905-25403072905-25303072905-25213072905-251030BioBasicPheynl（5 m）色谱柱订货信息 4.6mm4.0mm3.0mm2.1mm1.0mm50mm72405-05463072405-05403072405-05303072405-05213072405-051030100mm72405-10463072405-10403072405-10303072405-10213072405-101030150mm72405-15463072405-15403072405-15303072405-15213072405-151030250mm72405-25463072405-25403072405-25303072405-25213072405-251030BioBasicSCX（5 m）离子交换柱订货信息 4.6mm4.0mm3.0mm2.1mm1.0mm50mm73205-05463073205-05403073205-05303073205-05213073205-051030100mm73205-10463073205-10403073205-10303073205-10213073205-101030150mm73205-15463073205-15403073205-15303073205-15213073205-151030250mm73205-25463073205-25403073205-25303073205-25213073205-251030BioBasicSEC色谱柱订货信息名称孔径规格(mm)订货号BioBasicSEC6060?300x7.873305-30784660?150x7.873305-15784660?30x7.8(保护柱)73305-037821120?300x7.873405-307846BioBasicSEC120120?150x7.873405-157846120?30x7.8(保护柱)73405-037821300?300x7.873505-307846BioBasicSEC300300?150x7.873505-157846300?30x7.8(保护柱)73505-0378211000?300x7.873605-307846BioBasicSEC10001000?150x7.873605-1578461000?30x7.8(保护柱)73605-037821
