Two Efficient Methods for the Conjugation of Smooth-Form Lipopolysaccharides with Probes Bearing Hydrazine or Amino Groups. II. LPS Activation with a

This chapter presents a conjugation method for coupling probes bearing hydrazine or primary amino groups to a lipopolysaccharide (LPS). LPS is modified by the activation of the hydroxyl groups present in its O-antigen moiety with 1-cyano

填充柱超临界流体色谱系统中的溶剂效应

摘要：考察了填充柱超临界流体色谱法(SFC)中的样品溶剂及连续进样等因素对化音物慑留行为变化的影响规律。 以超临界C02或者低体积分散甲醇的CO2为流动相时，氨基柱上组分的保留时间随着样品溶剂的极性增大而增大，而溶剂对CO2柱上组分的保留时间影响不大；在CO2柱上，溶剂对连续进样的后续效应不强，而在氨基柱上，甲醇溶液的后续效应比丙酮、氧仿溶液的后续教应强 当甲醇的体积分数大于1.0%时，溶剂的效应明显减弱，这种变化规律对填充柱SFC的合理进样并获得重现性良好的色谱数据具有实际意义。
