News 31st October 2019 Tokyo, Japan— Tosoh Corporation is pleased to announce its consolidated results for the first half o.; 31st October 2019 Tokyo, Japan— Tosoh Corporation has revised the full-year fiscal 2020 consolidated financial results. The EcoSEC High Temperature GPC System has four independent heating elements that maintain a constant temperature within the range of 40 ºC to 220 ºC: pump oven, column oven, autosampler, and RI detector. HLC-8320GPC is a dedicated size exclusion chromatography (SEC) system equipped with the functions necessary for SEC analysis. And the GPC Workstation EcoSEC-WS gives full control of the main unit, enabling molecular mass analysis with excellent operability and high precision.

Instrument Description:
EcoSEC (HLC-8320GPC) is a new generation of dedicated high-performance integrated gel permeation chromatography, with the polymer molecular weight and molecular weight distribution of the functions required for accurate analysis. As nearly 40 years experience in the development of TOSOH GPC company launched in 2008, the seventh generation GPC system, EcoSEC not only inherits the advantages of conventional integration products, but also in terms of hardware and software and uses some of the latest technology, the instrument as a whole performance has been further improved, which can greatly improve the efficiency of GPC analysis, as well as more stable, more accurate analysis results.
With excellent linear calibration curve using TSK-GEL SuperMultiporeHZ series of semi-micro SEC columns, and the amount of organic solvent using standard sample preparation errors to a minimum standard polystyrene packages PStQuick, can greatly increase the separation speed and separation efficiency, save and to reduce the difference between the measurement instrumentation system results impact.

main feature:
1. The overall temperature
Unlike other brands at room temperature GPC system, EcoSEC column not only for temperature control, but the high temperature GPC temperature control design applications on normal temperature GPC instrument within the system's various components, including the infusion pump, column and detection , a whole temperature control. This design makes the solvent prior to entering the infusion pump to reach a constant temperature, to obtain a higher stability of the infusion, to reduce the influence of the solvent volume with the temperature change of the detection signal can be obtained more stable differential (RI ) at baseline, more stable analytical results.
2. The flow-path system
GPC instrument equipped with differential (RI) detector, the detector is in the sample cell (sample cell) the difference between the refractive index of the reference cell (reference cell) in the solution and to characterize the sample. Currently on the market other brands GPC's RI detector, in the analysis of the reference sample solvent tank is fixed does not flow from the strict sense, we can not be called a true reference. The EcoSEC uses a flow-path design, the addition of a reference flow path of the infusion pump, making the whole system from the infusion pump, the column to the detector cell, is divided into separate sample and reference two flow paths, so that differential detector reference a real sense of reference to ensure as much as possible to reduce the impact of changes in the nature of the solvent itself of the detection signal can be obtained more repeatable and more precise separation results.
3. The world's smallest RI detection cell
EcoSEC system using RI detector by TOSOH company developed the design and production, and its detection cell volume of only 2.5uL, and RI detector volume commercial currently on the market mostly in the 8 ~ 10uL. Smaller detector cell volume While detector processing technology put forward higher requirements, but its benefits is that it can improve RI detection sensitivity and accuracy, which can be more reliable and more accurate results.
4. semi micro column
GPC analysis in order to meet the user's efficient, rapid and high-throughput and other performance requirements, TOSOH company developed a new generation of semi-micro column, the size of 4.6mmID * 150mm, particle size is 3um. Because the use of smaller particle size filler, semi-micro column can be a conventional column with the same efficiency (compared to single column), and therefore the use of semi-micro column instead of a conventional column, to give the same separation premise, a single sample analysis time can be cut by half to reduce solvent consumption to 1/6, and the sample injection volume can also be greatly reduced.
5. Simple operation
By using GPC workstation EcoSEC-WS, can be easily preheated instruments, analysis and shutdown operations. Also can be independently controlled by the operator control panel on the host.
Self-cleaning function eliminates the procedure for replacing the solvent, and other time-consuming manual operations.
