QuadJet™ SD

LECO's QuadJet™ SD is the ideal solution for samples which arrive in your lab. By combining the sensitivity of Flame Ionization Detection (FID) with the increased chromatographic resolution of comprehensive two-dimensional gas chromatography (GCxGC), the QuadJet SD delivers a better measure of the actual components of your sample than a straight GC analysis. No other system available on the market can deliver the same reduction in noise and error as the QuadJet SD.
