WebbThe separation was carried out at 25°C, and the injection volume was 5 μL. The proposed method has an advantage of a very simple sample pretreatment, and is much faster than the currently utilized HPLC methods using gradient elution and UV detection. WebbThe injection loop is a critical component of an HPLC and is potentially one of the largest sources of excess HPLC system volume. The sample is injected into...
Webb9 nov. 2015 · By applying trap columns, injections of volumes larger than 5 µL are possible without risking the damage of the separation column or peak broadening due to the enforced peak displacement on the column. WebbWith an graphy in the analysis of residues in terms of specificity injection volume of 5 ml, this value corresponds to and limits of detection. 1.64 fmol (or 0.43 pg), enhancing 40 times the Figure 4 shows chromatograms with HPLC-FD sensitivity in comparison with conventional fluores- and HPLC-LIFD for the same standard solution cence ...
