Using a patent pending manufacturing process, our new inlet gold seals eliminate tiny leaks from machining that can negatively impact your GC performance.

• Improved production process gives smoother surface for better seal
• Inert gold surface applied with a proven proprietary plating process
• New kit includes washer – at no additional cost
• Better packaging to ensure cleanliness
• The new gold seal (5188-5367) is an enhancement of original gold seal (18740-20885)

The gold seal forms a leak-free seal with the bottom of the inlet body and column ferrule to minimize both sample contamination and sample loss. Even small leaks in the split/splitless injection port can reduce system sensitivity, cause poor signal-to-noise ratio, increase column bleed, and even shorten column life. Using a patent-pending manufacturing process, our inlet gold seals eliminate tiny leaks from machining that can negatively impact your GC performance. Our gold seal is made with a metal injection molding process that provides a consistent, smooth surface, without ridges and grooves from a machined process. The seals are then polished and gold plated for smooth surface. For convenience, the gold seals are carefully packaged with the inlet seal washer.

To prevent loss of active analytes due to adsorption or decomposition during sample vaporization, Agilent proprietary Ultra Inert chemical deactivation process is available on top of the gold plating making the best sealing surface the most inert! Inertness is added to the best sealing surface for inlets. For best trace level analysis, use Ultra Inert gold seals along with other Agilent Inert Flow Path components to obtain inertness from injection through detection.
