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.
Excellent choice for LC/MS. Highly retentive phase for hydrophobic and slightly polar analytes
