一般描述
SUPELCOSIL™ LC-NH2 Supelguard™柱芯[5 μm粒径，长度×内径：2 cm×4 mm]，在2 cm长的不锈钢柱体含有SUPELCOSIL填料，并用聚醚醚酮（PEEK）封装的不锈钢熔块（2 μm孔隙度）封闭。Supelguard试剂盒（包括1个柱芯、1个独立式柱套、管道和2个螺母和套圈）可实现在任何分析柱中使用这种柱芯。直连式保护柱套可以将Supelguard柱芯与Supelco分析柱直接相连。我们只提供两只装3.0 mm柱芯，独立式或模块化保护套需要单独购买。内径3.0 mm的小体积柱芯是保护含3 μm颗粒分析柱的绝佳选择。

An analytical method was developed and validated for the determination of maltodextrin in raw milk, using high-performance liquid chromatography with evaporative light scattering detection. Maltodextrin content was evaluated in adulterated raw milk using a Supelcosil LC-NH2 (25cm×4.6mm) column and isocratic
