Dimethyl-modified standard silica layers available as glass plates or ALUGRAM® aluminium sheets. Recommended for active plant constituents and steroids.

Supplier: Restek

Molecular sieve 5A PLOT columns are designed for efficient separation of argon/oxygen and other permanent gases, including CH₄, C₂H₆, and CO.

Supplier: Restek

These application-specific columns with proprietary crossbond phases are suitable for organochlorine pesticides and herbicides.

Supplier: Agilent

Agilent Technologies extended light path capillaries ('bubble' cell capillaries) can be used to improve sensitivity 3- to 5-fold over standard capillaries. With extended light path capillaries, the inner diameter is increased only at the detection window, offering the sensitivity of a wide inner diameter capillary and the low current generation of a narrow one.

Supplier: Restek
