The column is the heart of the system, packed with a solid material (the stationary phase), typically silica with C18 (18-carbon chains) bonded to it for reversed-phase HPLC, which is standard for peptides
Room temperature storage degrades the peptide rapidly, reducing potency and potentially creating degradation products you do not want to inject
