Standard Polysiloxane GC Columns. DB-200 is a (35% trifluoropropyl)-methylpolysiloxane column. This mid-polarity column is ideal for difficult-to-separate positional isomers. It has unique interactions with compounds containing nitro, halogen, and carbonyl groups. Features: • (35% Trifluoropropyl)-methylpolysiloxane • Temperature limits of 300 °C isothermal and 320 °C programmed • Mid polarity, more polar than DB-1701 or DB-17 • Ideal for difficult-to-separate positional isomers • Unique interactions with compounds containing nitro, halogen, and carbonyl groups • Low ECD bleed • Unique selectivity • Close equivalent to USP phase G6 • Tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency • Performance Summary shipped with each column
