New Zebron™ Inferno™ GC Columns Bring High Temperature Stability to Mid-Polarity Analyses
Phenomenex Inc., (USA) announces the expansion of its successful Zebron Inferno high-temperature GC column line, adding two new mid- polarity columns. The new ZB-XLB-HT and ZB-35HT are the first mid-polarity columns that can withstand temperatures up to 400o
C, enabling analyses
of compounds with high molecular weights and boiling points. The Zebron Inferno non-metal columns are stable at high temperatures due to proprietary coating and binding technologies, providing long lifetime, low bleed and low activity. They are ideal for analyses in environmental, food and beverage, pharmaceutical, toxicology and biofuels applications. Standard fused-silica columns are not engineered to withstand temperatures above 380o
C and their polyimide coating begins to degrade, eventually becoming brittle
and inflexible. The Phenomenex Inferno columns are specially designed for high-temperature analysis, with more rugged stationary phases and coating. The ZB-XLB-HT Inferno column is stable up to 400o
C and provides unique selectivity for confirmational analyses. This MS-certified column offers low activity and good peak shape for acidic
and basic samples. The ZB-XLB-HT proprietary phase is ideal for polychlorinated biphenyls (PCBs), pesticides, herbicides and many EPA methods. The ZB-35HT is a 35%-phenyl-65%- dimethylpolysiloxane intermediate-polarity column that is stable up to 400o
C, enabling high molecular weight analysis. It is particularly well suited for trace analysis with bleed-sensitive
detectors. Applications include semi-volatile compounds, pesticides, drugs of abuse, pharmaceuticals, steroids and many EPA methods. “Our successful Zebron columns were the first non- metal columns to provide stability at very high temperatures,” commented Ngoc Nguyen, brand manager for Phenomenex. “The increased column stability can be beneficial even for routine temperature ramps above 320°C, which can cause some GC columns to become brittle and produce high bleed.”
Reader Reply Card No 128 Biodiesel Quality Improved by Rapid Analytical Control
Foss (Denmark) announces the XDS Biodiesel Analyser, a rapid and easy-to-use solution for improved control of biodiesel production. The XDS instrument is supplied pre-calibrated and ready to test a range of key control parameters throughout the process. It can be used to test deliveries of vegetable oils used as raw material, for monitoring the effectiveness of the biodiesel conversion process and for testing against biodiesel standards such as ASTM and EN14214/ASTM6751. Compared to existing analysis options, the XDS is significantly faster and easier. This promotes improved quality while reducing costs and wastage. For instance, monitoring of diglyceride during the conversion process ensures to optimal dosage of catalyst in line with standards. A measurement with the XDS instrument take about two minutes compared to about an hour with traditional GC analysis. The XDS is also simpler to use, allowing anyone working in the plant to contribute to quality without the risk of human error that can occur with operators unfamiliar with the GC technique. To do a test, a sample is placed in the XDS and the results are then displayed on a computer screen. A user of the XDS system is SunOil biodiesel in The Netherlands. In an interview for Foss In Focus magazine, laboratory manager, Marc Arends, said: “In the past there was some doubt about some of the results because obviously not everyone working in the plant is a trained laboratory technician, but now it is so simple to make a measurement that the human error is removed.”
Reader Reply Card No 129 Easy-to-Use Portable IR Analysers for Biofuels Measurements
Last Autumn, transportation of biodiesel through a US pipeline represented a major milestone in the biofuels marketplace. On-site blend analysis was crucial -- both at the beginning of the pipeline and at the end -- to ensure it met specifications. These tests were done using Wilks Entrprise Inc.’s (USA) InfraCal Biodiesel Blend Analyser and InfraSpec VFA-IR Spectrometer from Wilks Enterprise. While the application of measuring biodiesel blend ratio is relatively new, the technology is not. Wilks Enterprise has been making specific analysis instrumentation for a number of industries since 1995. Over 2000 InfraCal Analysers are in worldwide use in the petroleum industry measuring oil in wastewater. For biofuels, analyses include blend ratio of biodiesel and ethanol in gasoline, FFA and water in biodiesel feedstock, total glycerides during biodiesel production and water in methanol or ethanol.
InfraCal Biodiesel and Ethanol Blend Analysers are preset for one analysis, either biodiesel or ethanol blend, and can be operated by personnel with no scientific background. The InfraSpec VFA-IR Spectrometer, a spectral range infrared analyzer, will measure biofuel blends as well as other parameters. It also can be used by non-technical personnel for a direct numeric readout or by laboratory personnel familiar with infrared spectra for more detailed analyses. All analysers are rugged, compact, and portable. They can be operated from a battery pack or a cigarette lighter adapter cable and analysis takes less than one minute.
As government incentives, regulations and funding for biofuels continue to expand, significant events like pipelines transporting biodiesel will become more common place. The InfraSpec Spectrometer and InfraCal Analyzers are currently used by major oil companies, pipeline transportation companies, and regulatory agencies such as the US Weights and Measures. The quick and easy analysis makes them ideal for a laboratory, fuel loading rack or even a measurement from a pump at a fueling station.
