HPLC Column
Welchrom Seires Hplc Column
ULTISIL SERIES HPLC COLUMN
Ultisil Series HPLC Columns are based on ultra-pure (purity > 99.999% spherical and totally porous silica. unique bonding chemistry and propritary surface modification techniques. producing excellent peak shape, column efficiency and exceptional lot-to-lt reproducibility. Ultisil coloumn is the best choies for method development owng to complete bonding chemistries and stable performance.
XTIMATE SERIES HPLC COLUMN
XTIMATE SERIES HPLC COLUMN
X features of Xtimate column
extra pH range from 1.0 to 12.5, excellent peak shape for strong bases
extra column lifetime: 5 times of similar product such as Gemini
extra performance: column efficiency of 5µm column is as high as 90000/m, 2-3 times of that of Xterra
extra care from welch: enjoy excellent pre-sales and after-sales service from welch
UHPLC COLUMN
Welch also offers Ultisil UHPLC (1.8hm) column. With high column efficiency and good lot-to-lot repro-ducibility. Ultisil UHPLC can generate high quality data, decreasing the probability of repeated sample analyses while reducing the consumption of solvent at the same time. Ultisil UHPLC series offer a vari-ety of bonded phases, specified guard column and pre-coloumn for the users to design and realize faster and more environmentally friendly chrom atography applications with higher resolution.
- Ultra resolution: some resolutions as or batter than that of conventional column which has more packing materials.
- Ultra speed: UHPLC offers more information per unit time and higher speed owing to its smaller partivles.
- Sensitivity: higher N, narrower peak width (W), higher peak hight. the system sensitivity of 1.8μm UHPLC is 70% ans 40%higher than that of conventional column of 5hm and 3.5hm packng, respectively.v
