In spite of the relatively low efficiency of OVM columns, it was possible to determine amounts as low as 0.15% of the unwanted isomer (usually D isomer) in commercial samples. The separations developed have been applied to the selection of commercial suppliers of protected amino acids (PAA),...
It's a complete, easy-to-use resource containing all of the LC columns, chromatograms and applica- tions you need. LC Columns The Agilent website offers important information and easy ordering on a full selection of Agilent LC columns, including ZORBAX brand. It gives you complete descriptions...
It is noteworthy that a variety of RP columns have been inspected during intact DAR RP-HPLC method development, including commonly used Varian PLRP-S, C4, C8, and C18 columns (data not shown). The selected Proteomix column gave the best performance in the separation of DAR0, DAR1, and ...
UV wavelength selection. To choose the most suitable wavelength, the four drugs dissolved in ethanol were scanned separately by spectrophotometer. Figure 4 shows that 230 nm is the most suitable wavelength attaining high sensitivity of the four drugs. It also did not conflict with the ...
