Shimadzu GC system with high sensitivity

Tracera traditional high sensitivity GC system GC detector is difficult to trace substances qualified gas analysis work, Shimadzu Corporation newly developed high sensitivity GC system Tracera, combines specially designed for capillary gas chromatograph GC-2010 Plus well BID detector design (Dielectric Barrier Discharge Plasma) technology, in this regard demonstrates powerful analytical advantage, fully able to meet the demand analysis of trace substances. High sensitivity TCD sensitivity than more than 100-fold higher than 2 times the sensitivity of FID highly versatile single detector fully meet the complex requirements of high stability analysis dielectric barrier discharge plasma generation technology to ensure long-term stability of the instrument to meet new plasma technology trace analysis of demand for new BID detector (Dielectric Barrier Discharge Plasma) is mainly ionized (ionization) by dielectric barrier discharge plasma generated helium, it is a highly sensitive universal detector. At lower temperatures, the quartz glass tube by the high voltage, generating a plasma with a high photon energy helium (17.7eV) a. Column effluent component in helium plasma bombardment ionization energy, collector detect ion signal output peaks. BID detector is Shimadzu Corporation and Dr. Graduate School of Engineering, Osaka University, Japan Atomic and Molecular Technology Center Katsuhisa Kitano cooperative research, it has received three US patents and four patents pending. Application comparison detector suitable compound dielectric barrier discharge plasma detector (BID) all organic and inorganic compounds (He and except Ne) the thermal conductivity detector (TCD) all organic and inorganic compounds (except carrier gas) flame ionization detector (FID) all organic compound (except formaldehyde and formic acid) high sensitivity TCD hundred times more sensitive than, more than twice higher than the BID FID and TCD detector sensitivity comparative analysis of permanent gases comparison of the two detector sensitivity differences. For organic compounds, BID sensitivity of the detector is 200 times more than TCD; for permanent gases, BID TCD detector sensitivity is several times more. High sensitivity of permanent gases and light hydrocarbon compounds further analysis of permanent gases and light hydrocarbon compounds, conventional analysis methods need to configure a plurality of detectors, and when analyzing ppm levels of CO and CO2, methane reformer needs and FID detector with the ability to analyze. In this case, if you use BID detector is completely different, it can replace the two devices to achieve high sensitivity inorganic gases and light hydrocarbon mixtures simultaneous analysis. Contrast detection concentration range Note: The figure shows the recommended concentration detection range may vary depending on the compound structure analysis conditions and equipment vary actual analysis. The newly developed universal detector single detector fully meet the complex analysis requirements BID and FID detector sensitivity comparator FID detector for CH bond compounds with good response, ideal for hydrocarbons analysis, but containing carbonyl, carboxyl, hydroxyl ( poor or unresponsive response -OH), aldehyde (-CHO), halogens (fluorine, chlorine, etc.) compounds. In comparison, BID can greatly improve the sensitivity of the detector of the above compounds, and almost no difference in the sensitivity. Sensitivity comparison figure shows the difference in various solvents response of the FID and the BID. Hexane response value is set to 1, all compounds were higher than the sensitivity of BID FID, and the relative response is more uniform. Analysis of high-boiling compounds BID set temperature up to 350 ℃, fully meet the analysis requirements of the following n-C44 paraffin mixture. High stability of dielectric barrier discharge plasma generation technology to ensure long-term analysis instrument Photo BID detector stability under the plasma generation chamber, the discharge electrode without any contact with the plasma, this durable structure design makes the instrument totally unnecessary maintenance or BID consumable replacement. Long-term stability test analysis to assess the stability of long-term analysis, BID detectors sensitivity stability test, respectively, in the instrument run continuously 96h, 2688h, read the peak intensity value 3240h, 96h response time value is set to 1, the calculation 2688h and 3240h value, as shown at right, the difference is negligible. Trace gas analysis reproducible experimental samples of each component concentration of about 5ppm, using loop injection mode to sample a range of reproducible experiments, peak area reproducibility, at between 0.84% ??-1.80% RSD . Related applying a single system to fully meet various analytical requirements of high sensitivity GC system Tracera is based on GC-2010 Plus platform, the integration of newly developed BID Shimadzu detector (dielectric barrier discharge ionization detector), is universal gas chromatograph. Artificial photosynthesis research in artificial photosynthesis reaction product analysis is a branch of photocatalysis by imitating photosynthesis of plants, the water decomposition will produce hydrogen and storage, in order to obtain energy technologies. Artificial photosynthesis is expected to become recognized as photovoltaic, solar, biomass after the fourth-largest renewable energy. The following figure shows the photocatalytic reduction of carbon dioxide generated in the reaction while CO and H2 analysis. As can be seen from the figure, the amount of CO in the rapid increase with time, end of the reaction, the growth rate slowing down. Tracera systems over a single detector and a single carrier gas, achieve CO and H2 while high sensitivity analysis. Ethylene vinyl impurity analysis is an important organic chemical raw materials for the synthesis of a variety of polymers, ethylene purity raw materials to be measured. The following figure shows the ethylene impurities analysis: H2 (30 ppm), CO (2 ppm), CO2 (15ppm), CH4 (30 ppm) for analysis of trace impurities. Analysis also Tracera by a single detector and a single carrier gas, a permanent gas and light hydrocarbon impurities in high sensitivity. Lithium-ion batteries produce gas analysis when evaluating the performance of the aging status of the lithium-ion battery, the battery often requires analysis of the gas produced during the recession. Tracera is ideal for gas analysis. Generating gas analysis shown below shows the lithium-ion battery: extract gas from the lithium-ion battery and diluted import gas chromatograph for analysis. Tracera by a single detector and a single carrier gas to achieve a lithium-ion battery generates gas analysis.
