Heavy Fuel Oil Requires Heavy Lifting

August 19, 2022

Heavy fuel oil, also known as bunker fuel or residual fuel oil, is a complex mixture used primarily in the shipping industry. Over the years, the regulations on heavy fuel oil have become more stringent to control sulfur emissions that were damaging to the environment. As a result, this type of fuel is frequently limited to 0.5% sulfur by mass, and it is therefore critical to know the composition of your oil. Such a complex sample requires the sort of heavy lifting that can only be provided by a high-tech, high-resolution GCxGC mass spectrometer.

Expand your Toolbox with the HRT+

July 29, 2022

Gas chromatography-mass spectrometry (GC-MS) has long been an invaluable tool in a chemist's belt. With its ability to tease apart the compounds in a sample, identifying even trace analytes, it is able to perform specific tests and pinpoint what, exactly, is in the material being analyzed. But what can you do when GC-MS isn't enough?

Smarter Savings: Fast GC-MS

July 8, 2022

Around the world and across the board, prices are rising. As we battle with the realities of post-COVID supply chain issues and international wars, companies struggle to keep their own costs low. One unscrupulous way to do this is to use lower-quality ingredients. The average customer may not be able to notice the difference between a genuine or artificial citrus essential oil, for example, but being able to determine the constituents of the oil is vital for determining its quality and safety, as most citrus essential oil uses involve direct contact with humans.

Congratulations Coastal Chemist! Dr. Petr Vozka

June 17, 2022

In October, 2021, at ASMS, LECO announced its search for a new collaborator in GC-MS. As part of a pilot program, we were looking for someone whose lab was working on important or novel chemistry and could really benefit from the addition of a free Pegasus® BT GC-MS. At ASMS 2022, we announced our winner.

We Don't Know What We Don't Know (But GCxGC Can Find It)

May 27, 2022

LECO recently concluded a webinar series on agricultural applications of our instruments with a presentation by Dr Frank Dorman of Dartmouth College, Department of Chemistry, formerly of Penn State University, Department of Biochemistry and Molecular Biology. While at Penn State, Frank worked on an environmental forensic investigation of wastewater applied to agricultural fields.

Designed for Speed: Fast GC

May 6, 2022

Even the best-trained experts can only move as fast as their equipment will allow, and as helium prices increase and supplies drop, the fast spectral acquisition speeds of GC-TOFMS instruments stand ready to reap the benefits of fast GC separations afforded by utilizing hydrogen carrier gas.

While the advantages of helium as a carrier gas for mass spectrometers have long been known, it is a limited natural resource. On the other hand, hydrogen gas generators can be installed in any lab for a constant supply and, conveniently, increased chromatographic speeds.

Pesky Pesto Peculiarities and GCxGC Analysis

February 11, 2022

Pesto can trace its roots back to ancient times, though it really only started taking off in North America in the 1980s and 90s. Though the primary base is consistent, with pine nuts, basil, and olive oil, individual recipes vary. As canned and bottled pesto became more accessible, individual manufacturers developed their own unique flavor profiles. While these recipes are usually trade secrets, the power of GCxGC TOFMS can tease apart some of the differences.
