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.
Available exclusively from LECO, our L-PAL3 autosampler offers increased vial capacity, discrimination-free GC injections (ultrafast injections), an automatic tool exchange to switch between injector types (liquid, headspace, or SPME), minimized carryover, and the sensing of vial bottoms to avoid mis-injections.
The Easier Way To Make GC×GC Part Of Your Every-Day Analysis
Simply GC×GC from LECO is a free tool designed to walk you through the steps of creating an optimized GC×GC method for your complex samples. Create a GC×GC method from scratch, or convert an existing 1D method to GC×GC.
GC×GC Flow Modulator
Our innovative FLUX GC×GC flow modulator was designed with one goal in mind—to make GC×GC more routine, accessible, and easier for you.
Thermal modulation delivers the highest performance of any available modulator for GC×GC. Other types of thermal or valve-based modulators do not match up to the ruggedness, reliability, and performance of LECO's GC×GC modulator.
Ionization Source For Gas Chromatography Mass Spectrometry
The innovative Multi-Mode Source™ (MMS™) takes all of the advantages of the three most common ionization modes – Electron Ionization (EI), Positive Chemical Ionization (PCI), and Negative Chemical Ionization (NCI/ECNI) – and combines them into one easy-to-use source. No more hardware switching, no more alignment issues:
with the MMS, changing ionization modes is as easy as a click of a button.
Developed exclusively by LECO, ChromaTOF® is uniquely designed to meet the needs of today’s laboratory professionals by processing and analyzing the large amounts of data that are acquired with our time-of-flight instruments.

Bring the Power of Accurate Mass and Confidence to your Identification Problems
LECO's Identification Grading System (IGS) eases data review by allowing users to quickly see, justify, have confidence in, and report on which chemicals are in a particular sample.
