Finally! A True Peak Capacity Increase for GCxGC of Petroleum Samples

In their comparison of GC and GCxGC, Blumberg et al stated, “the peak capacity of currently practiced GC×GC does not generally exceed the peak capacity attainable from 1D-GC with the same analysis time…”. Seemingly, Blumberg’s main point was that the typical first dimension column in GCxGC is operated suboptimally. We lengthened this column to “naturally” increase peak widths and present here what we believe is the first “true peak capacity increase” for GCxGC.

GCxGC Analysis of Complex Petroleum Hydrocarbons: Sulfur Speciation in Diesel

Comprehensive 2D GC, also known as GCxGC, is a powerful technique with a great deal of potential for improving separations of complex petroleum and petrochemical samples that contain hundreds—or even thousands—of components. While GCxGC is still considered emerging technology and is used primarily in research and development labs, it has undergone significant growth in the past few years.

New Alumina Column Shows Promise for Analyzing Chlorofluorocarbons

Stable Sulfur & Mercury Sampling in Refineries Using Siltek^® and Sulfinert^® Surface Treated Components

Refinery and natural gas samples often contain trace amounts of sulfur- and mercury-containing compounds, which can interfere with reactions, poison catalysts in petrochemical processes, and damage equipment. Because these compounds quickly react with stainless steel surfaces, accurate determination of these compounds is impossible when samples are collected and stored in untreated sample cylinders. Restek's Siltek^® and Sulfinert^® passivation techniques bond an inert layer into the surface of stainless steel, preventing active compounds from reacting with or adsorbing to the steel.
