Gas Chromatography. GC Columns. Replacing the Gold Seal. Replacing the Gold Seal The primary purpose of the golden seal is to seal the inlet to help maintain the chromatographic conditions and also provide for uniformity in the distribution of the vapor in the inlet. It is housed within the injector portion of the instrument. Split/Splitless Inlet Gold Seals from Agilent. Even small leaks in the split/splitless injection port can reduce system sensitivity, cause poor signal to noise ration, increase column bleed, and even shorten column lifetime. Ensure optimal gas chromatography (GC) analysis by using exceptional sealing and inert properties of Thermo Scientific™ GC Injection Port Base Seals. Precision machined from high grade stainless steel, choose from gold-plated or Siltek-treated base seals. Gold-plated inlet seal may be used in the GC injection port for thermal desorption-gas chromatography/mass spectrometry (TD-GC/MS), where residual accumulation was noticed resulting in analyte adsorption and elevating signal background. Hence, replacing the gold-plated seal in regular intervals decreased the interference. 1. Gold is extremely resistant to almost everything. 2. Gold is soft, so seals well. These can oftentimes be re-used. On autombiles, oftentimes drain plugs, banjo seals, etc., are sealed by copper washers for similar reason: inert, and compress to seal well. Here is a video which shows how you can replace the gold seal inside the reducing nut The debris on the gold plate or even scratches on it can cause several problems for chromatogram such as
Thermo Scientific Gold Inlet Base Seals for all Agilent GC Split and Splitless machined for excellent sealing properties on split and splitless injection ports.
Want to know how to change the Gold Seal on your Gas Chromatograph? Let MIDI teach you how with this easy-to-follow instructional video. Any small particles present - such as a small bit of alumina powder - or dust, will change the surface of the cut and it will not match. An attempt to reuse a gold seal in a GC inlet is not a good idea. If you do not have a replacement, to not remove the old seal. Like many components inside a GC injection port, your inlet seal will become dirty over time. As a result, inlet seals need to be replaced periodically, ideally as part of a scheduled routine how do you choose the right inlet liner for your analysis? Each style of inlet liner offers a different range of benefits – to get the best performance, the key is to choose a liner that is well-suited for your injection type, sample, and budget. Below is a basic overview of liner styles.
