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.

"I have used the LECO BT4D for the separation, identification, and quantification of anabolic steroids.
The advantages of the GC×GC system to separate stereoisomers in a complex matrix means time can be saved from doing complex sample preparation and extraction procedures. The ability to separate and quantify low levels of target analytes from high levels of matrix interferences has been key to my work. With LECO’s user-friendly ChromaTOF software, expert application scientists, and fantastic technical service team, LECO is a reliable and trusted research partner."
Dr. Belen Morales, Head of Analytical Services from the Sheffield Assay Office in an interview with LECO
"[...] I have experience with LECO for years. To summarise is very, very simple. The reason why I bought the last machine from LECO, the Oxygen, Nitrogen, Hydrogen analyser was because in the market it’s the best in terms of practicality. The fact that I can do the multi element analysis at the same time for Oxygen, Nitrogen and Hydrogen is a really benefit for me. You do not have this in most other competitors. Also, the aftersales service is something that is perfectly working for LECO. We have service contracts with LECO on all our instruments and are very happy with the aftersales support we get. [...]"

LECO Solutions for MOSH/MOAH
Whatever your sample preparation workflow requirements are, harness the power of LECO GC×GC & TOF technology to solve the complex challenges of MOSH / MOAH Analysis.
When the Kaunis Iron Mine opened in Sweden, it was the newest in one of Sweden's biggest industries. The mine contracted with Degerfors Laboratory (D-LAB) for their iron analysis. Before analysis could be run on the samples, however, the ore had to be dried and moisture levels measured.
D-LAB had a problem: their current moisture determination methods used a manual balance that could only handle one sample at a time, requiring a technician's attention every five minutes. The ISO 3087:2020 method used was also a problem, as a single run could take more than 5 hours to complete. The lab turned to LECO for a solution.
