pump may be heated if solvent is very viscous,温度在gpc分析中的作用,流速的精度,精确的流速对方法的可靠(可重现)性,样品间、实验室间及每天的重现性是非常重要的 对gpc的要求要比对一般的hplc的要求高 非常好的流速精度对gpc极为重要 流速精度可用作诊断工具来监测方法或仪器的性能 流速精度对要求低 18、...
The samples dissolved in the liquid mobile phase (an organic solvent or aqueous solution) and carried through the stationary phase consisting of porous gel particles. The smaller molecules can diffuse into these pores more readily than the larger molecules, and thus spend more time in the pores,...

This ensures that solvent and mobile phase have comparable compositions of mobile phase components. Thus the redistribution of mobile phase components on the stationary phase is less pronounced, resulting in lower peak areas for system peaks. Figure 3 shows an example of an aqueous separation. The ...
Alpha GPC is a valuable supplement for athletes or anyone who wants to perform better, build lean muscle mass, feel peak energy during a workout and recover quickly afterward. A pilot study indicated that a 600 mg dose of Alpha GPC taken 90 minutes before bench pressing increased ...
Solvent and concentration dependence of hydrodynamic volumes and GPC elution volumesHydrodynamic VolumeElution VolumeGPCGyration RadiusThe sizes of dissolved polymers can be estimated a priori at infinite dilution and under theta conditions from existing theories. The effects of concentration can be ...
While the plate count measurement on column arrival should be performed using the conditions on the column certificate, plate count tracking should be done in the eluent applied for the actual GPC/SEC analysis, to prevent frequent solvent exchange. ...

Degasser The degasser has an efficient low-volume design, which means that mobile phases can be rapidly exchanged for quick solvent changeover and reduced downtime. This helps reduce mobile phase exchange time to less than one hour compared with at least 2-3 hours in the TDAmax. Autosampler Th...
