General description
On-Column injection is generally performed to avoid vaporization of samples. This method involves injecting the cold sample directly on the column. Using retention gaps allows autosamplers to use on-column sample injection method.[1] In this system, a 32-gauge needle is inserted in a cool narrow bore injection valve and then into capillary column.[2]
The fixed needle design of this Hamilton syringe minimizes dead volume. Stainless steel needle, 12.5 cm (for Agilent/HP injectors) or 7.5 cm (for Carlo Erba injectors) × 0.24 mm O.D. (32 ga.), 90° tip. Use with 0.32 mm I.D. or larger columns.
Application
It may be used in a study done to understand the variations of capillary on-column fixed needle injection system in gas chromatography.[2]

Mitochondrial oxidative phosphorylation (OXPHOS) and substrate utilization critically regulate the function of hypothalamic proopiomelanocortin (POMC)-expressing neurons. Here, we demonstrate that inactivation of apoptosis-inducing factor (AIF) in POMC neurons mildly impairs mitochondrial respiration and decreases firing of POMC neurons in lean
