GC PACKED COLUMNS

packed_columnWe make custom-packed GC columns using high-quality materials. Any stationary phase can be chosen from our listings on page 3, in combination with nearly all listed supports. The use of other stationary phases are subject to special quotation. Columns are supplied as 6” diameter coils, unless instrument make, and model is specified, or dimensions are specified.

Stationary Phases

Usually, the solid support will be coated with a liquid stationary phase. Exceptions are molecular sieves and porous polymers such as HayeSep® or Porapak®, which are normally used un-coated. For a complete listing of available stationary phases.

Solid Supports

Porous Polymer Supports

  • HaySep A, B, C, D, DB, DIP, N, P, Q, R, S, T
  • Tenax®
  • Porapak N, P, PS, Q, QS, R, S, T

Molecular Sieves
