by PerkinElmer
This is PerkinElmer's LC/MS HPLC Conventional Column line. This line of columns is made of (60 Å) silica which results in large surface area, high carbon loads, and high retention compounds. Columns are available in 3 or 5 µm and lengths ranging from 30-250 mm, in 2.1 and 4.6 i.d. The Brownlee Choice family includes the Basix, C18, Organic Acids, and PFP Propyl phases.
Enhanced retention and selectivity for polar organic acids. Retention is stable and reproducible even with 100% aqueous mobile phase specified in the AOAC method.
