(35% Trifluoropropyl)-methylpolysiloxane 300/320°C temperature limit Midpolarity (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...

low-polarity phase; Crossbond 5% diphenyl/95% dimethyl polysiloxane Active basic compounds that otherwise require derivatization, or an alternative analytical technique, can be analyzed on an Rtx-5 Amine column. The tubing surface is chemically altered to reduce tailing of basic compounds,...

GC capillary columns are typically wound on 7 inch cages that fit into standard-sized GCs like the 6890. The 6850 GC has a smaller oven which requires the use of columns wound on a smaller cage diameter. Nitroterephthalic acid modified polyethylene glycol High polarity Temperature range from 40 to...

Restek Rt-Alumina BOND columns are highly selective for C1–C5 hydrocarbons and separate all saturated and unsaturated hydrocarbon isomers above ambient temperatures. The reactivity of the aluminum oxide stationary phase is minimized, by deactivation with inorganic salts like KCl or...

GC capillary columns are typically wound on 7 inch cages that fit into standard-sized GCs like the 6890. The 6850 GC has a smaller oven which requires the use of columns wound on a smaller cage diameter. DB-5 (2713R99, T86, T94 and V89) (5%-Phenyl)-methylpolysiloxane Non-polar Excellent general...

In packed columns, the carrier gas percolates through the porous bed. In a packed column, separation is achieved by moving the solutes apart. Packed columns are made up of two main materials; stainless steel and Pyrex glass. Metal packed columns are more suitable for long and high carrier gas flow...

GC capillary columns are typically wound on 7 inch cages that fit into standard-sized GCs like the 6890. The 6850 GC has a smaller oven which requires the use of columns wound on a smaller cage diameter. Porous divinylbenzene homopolymer A PLOT column with polarity between Porapak-Q and Porapak-N...
