Zero Dead Volume Fittings for Gas Chromatography

Valco excels in all critical areas of the design and manufacture of fittings. For analytical systems to reach and maintain optimum performance levels, it is essential to consider interchangeability, counterbore tolerances, ID/OD concentricity, cleaning procedures, and ferrule shape when it comes to fittings. This interchangeability extends throughout the Valco and Cheminert fitting and valve product lines. Indeed, the Valco standard has been so widely copied that Valco and Cheminert fittings are, in general, fully interchangeable with those of other major manufacturers. Many major GC systems manufacturers integrate Valco’s high-quality fittings to improve analytical performance.
