column, which in turn can reduce column life. Johnny Mitchell, president of ESC Lab Science, says that the guard chip will bring “a signifi cant improvement in productivity for the lab”. He adds that the effi ciency of the Intuvo’s sample fl ow pathway can both decrease maintenance time and improve the quality of the data. When combined with mass spectrometry (MS), the Intuvo-9000 is ideal for high-throughput contract laboratories, and for labs dealing with challenging sample matrices in fi elds such as food, environmental, chemical, pharma and forensics testing.

(formerly Cambridge Scientifi c Instruments) can carry out conventional and fast gas chromatography with an air- blown oven, but also performs ultra-fast gas chromatography (UFGC) with directly heated columns. T e company states that the 500 Series can reduce cycle times by up to 10 times whilst using a fraction of the energy a conventional GC requires.


When operating in


conventional GC mode, the 500 Series uses its compact air-blown oven and low energy heat recovery heating system. In ultra-fast mode, metal capillary columns are directly resistively heated, allowing increased ramp rates and higher upper temperature limits, as well as decreased cool-down times and reduced energy consumption.


Ellutia developed the 500


Series for the oil and gas sector but foresees the device being used widely in many fi elds thanks to its versatility.


New rapid gas analyser Another recent GC development, Scion Instruments’ Rapid Gas Analyser is an enhancement to the fi rm’s gas chromatograph type 456, which aims to give shorter run-times and improved repeatability for all gas samples. By utilising the latest technologies in instrumentation and column technology, the Rapid Gas Analyser uses single confi guration for practically all gaseous applications: bulk as well as trace; irrespective for purity analysis in permanent gases or light hydrocarbons or bulk determination in various


Scion Instruments’ Rapid Gas Analyser is designed to provide shorter run times
