In the current paper, 14 different brands of magnetic caps with silicone–polytetrafluoroethylene (PTFE), butyl–PTFE, or butyl rubber septa were tested. The total emission of septa over a 4 h
Carrier Gas The carrier gas plays an important role, and varies in the GC used. Carrier gas must be dry, free of oxygen and chemically inert mobile-phase employed in gas chromatography. Helium is most commonly used because it is safer than, but comprable to

Abstract. The significant presence of septum-related ghost peaks, causing interference in routine gas chromatography–mass spectrometry analyses at sample inject Different septa shown in Figures 2A–2D used in this study were obtained from various sources, including:SGE Analytical Science (Australia, part nuer 041904; suggested appliion maximum temperature of 400 C); yellow PTFE coated
The rubber septa of split-splitless GC inlets limit how samples can be introduced; 32-gauge on-column needles are too flexible to penetrate unmodified septa , and needles thicker than about 1.5
Septa Rubber or silicone discs which are used inside the injector for introduction of sample into the chromatographic system. The syringe needle penetrates this disc at the time of sample injection

On the other hand, butyl rubber–PTFE septa are mechanically hard and more resistant to the absorption of the constituents of a sample, and it is stable up to 130 C (12, 14). Kolb et al. showed that in using silicone–PTFE rubber septa, 69% of acetone and 89% of dichloromethane were lost, while in butyl–PTFE rubber septa, the losses were less than 3%.
When the needle pierces the septum, the rubber is exposed to the sample by either headspace or direct contact, which will affect the quality of the data in various ways. This appliion note discusses the influences of pierced PTFE/silicone septa in GC-MS

28/10/1975 The injector is for gas chromatographic apparatus and other equipment where a sample is to be introduced through a hollow needle which is pushed through a septum. The two or more septa are arranged in relative positions so that the hollow needle first penetrates one septum whereby the tip of the needle enters the interior of the injector chaer.
An Aijiren Septum is Not Just a Septum White Paper The septum is one of the three main components of your sample containment system, consisting of the vial, septum, and cap. The septum is highlighted in red in Figure 1. Autosampler needle Septum Cap Vial
