Simultaneous Three-Column Analysis with a Single Sample Injection and No Column Replacement Provides More Efficient Investigation of Separation Conditions
Analyzing moisture, and how much of it, is critical to the performance of petroleum products, as well as infrastructure and product integrity. For example, moisture in petrochemical feedstock can cause pipelines and valves to freeze, as well as poison some catalysts. One popular method used to analyze for moisture is Karl Fischer Titration (KFT). KFT […]
A gas chromatograph is used for impurity analysis of intermediate or final products in various chemical fields. The table below shows our System GC lineup. Access detailed application information by clicking on.
Periodical monitoring of calorific values is necessary to ensure a stable supply of town gas. Since Shimadzu’s system GC is robust and designed for automated analysis, it is widely used for 24 hour/day online analysis in this field. Dedicated software is able to calculate calorific values and indexes automatically. Using the sample line selctor SLS-2020, […]
Gas containing inorganic gases and hydrocarbons is typically analyzed in any number of industries using a gas chromatograph (GC). Generally speaking, either a flame ionization detector (FID) or a thermal conductivity detector (TCD) is selected depending on the type and concentration of the gases being analyzed. However, a gas analysis system equipped with a barrier discharge […]
High-purity gas is necessary in industries such as chemical, medical, and foods. Precisely controlled GC enables identification and quantitation of a trace amount of impurities in bulk gas. If the gas resources in a factory consist of multiple lines, a sample line selector SLS-2020 can be utilized to switch sample lines automatically, allowing a single […]
It is necessary to analyze outgas in transformer insulation oil in power plant facilities. Shimadzu offers a System GC compliant with ASTM D 3612 Method B (oil stripper sampling) or ASTM D 3612 Method C (headspace sampling). The Nexis GC-2030TOGAS3 system, equipped with a PDHID, enables the analysis of more trace amounts of permanent gas […]
VUV system is compliant with ASTM D8071/D8267/D8368/D8369/D8519. Vacuum ultraviolet (VUV) spectroscopic detectors can provide a new dimension of chemical analysis accuracy for hydrocarbon analysis. VUV light creates unique spectral signatures in the gas phase that result in unambiguous compound identification and quantitative analysis across a wide spectrum of complex applications.
The purpose of detailed hydrocarbon analysis (DHA) is to determine the bulk hydrocarbon group type composition (PONA: Paraffins, Olefins, Naphthenes and Aromatics) of gasoline and other spark-ignition engine fuels that contain oxygenate blends (Methanol, ethanol, MTBE, ETBE, and TAME) according to ASTM D6730. PONA analyte identification is conducted by matching retention indices with normal hydrocarbon […]
A gas chromatograph is used for composition analysis of gasoline and its additives in order to improve fuels’ performance. In addition to excellent performance, Shimadzu’s GC systems improve productivity. For example, the Nexis GC-2030 system combines three standards into one to save analytical instrument and labor costs.
