Accurate Analysis of Glycerol and Glycerides in Biodiesel Oil Using EN 14105 (2011) and Robust Metal MXT Columns

The high temperatures required to analyze glycerol and glycerides as contaminants in biodiesel can result in shorter column lifetimes and more instrument downtime. Metal MXT-Biodiesel TG columns are more durable and last longer than their fused silica column counterparts, making them a better choice for labs wanting to minimize downtime. As demonstrated here, MXT-Biodiesel columns meet method EN 14105 (2011) performance requirements and provide excellent chromatographic results for biodiesel testing.

Using Alternative Carrier Gases with Accelerated ASTM D2887 Simulated Distillation Analysis

ASTM Method D2887 now allows for alternate carrier gases, so hydrogen or nitrogen can replace helium carrier gas for simulated distillation. Here, we show that with an MXT-1HT SimDist column and Restek’s EZGC online method translator existing methods using helium can be easily converted to either hydrogen or nitrogen carrier gas. Because retention times are preserved with proper method translation, there are minimal changes to peak identification tables which significantly simplifies method validation.

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.

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.
