Features of HILICpak VG-50 Series (2) (Stability of Baseline using Corona Charged Aerosol Detector)

HILICpak VG-50 shows a stable baseline and reduced noise level by corona charged aerosol detection (CAD) due to the polymer packing materials. CAD detects nonvolatile and semi-volatile analytes eluted from the column with high sensitivity; the stability of the baseline is heavily influenced by bleeding of the packing materials.
