WebAug 14, 2024 · Compared with allodiploids, allotetraploids also showed higher nonstructural carbohydrate (NSC) contents during development according to HILIC-CAD results. The expression levels of sucrose metabolism-related genes were higher in allotetraploids than in allodiploids at the same time points. WebMay 10, 2024 · One possible strategy for using CAD for purity testing of ibandronate sodium was the use of long-chain, volatile, basic ion-pairing reagents, which can cause dynamic modification of a C8 reversed phase and thus emulate the mixed-mode mechanism.
As a general recommendation for HILIC standard methods, select a 100 or 150mm long column, packed with 3 - 5µm particles and with a 4.6mm id, if using UV detection. If HILIC is coupled to MS or CAD detection, use a smaller column, e.g. 100 x 2.1mm or 50 x 2.1mm, packed with 3-5µm particles.
