Nhà sản xuất: Shimadzu
Nexis GC-2030, Shimadzu's premier gas chromatograph, offers a modern approach to a classic chromatographic technique. Designed with the user in mind, new innovative features, exceptional performance and high-throughput capabilities will elevate your lab to the next level.
Analysts will benefit from the touch panel interface, which features clear graphics that display information instantly whenever needed. The user-friendly interface leaves the operator free to focus on obtaining optimal analytical results.
Main settings controllable via the touch panel on the GC unit:
The automatic start and automatic stop functions reduce running costs. The automatic stop function can save electricity by automatically stopping GC temperature control when analysis is completed. Later, after a specified time has elapsed, it also stops carrier gas and detector gas control. The automatic start function starts gas control after a specified period of time and then starts temperature control.
Comparison Between With and Without Using the Automatic Start/Stop Functions
With the split/splitless sample injection method, the carrier gas saving function can reduce the amount of carrier gas released beyond the system from the split flow lines after transfer of the samples to the column during analysis.
Additionally, by using an optional gas selector, He can be automatically switched to an alternative gas such as N2 when providing gas to the units outside of analysis times. The gas can be saved when used in combination with the carrier gas saver function, or even with the total volume injection method where the carrier gas saver function cannot be used. Control is integrated with LabSolutions, enabling gas switching to be configured seamlessly.
The operational status of the instrument can be confirmed using the self-diagnostic (system check) function. Periodic diagnostics help prevent unexpected downtime.
Check for leakage of gas from the sample vaporization chamber with a single tap. Checks can be performed with the column attached as is, thereby speeding up the procedure.
ClickTek connectors* make tool free column installation a snap. The click sensation felt when finished attaching the column provides a more reliable connection and ensures a better seal under all operating conditions. *Optional
The injection port can be opened or closed without tools by simply sliding the ClickTek lever. Replace the insert, slide the lever and feel the click for a leak-free install every time.
The LabSolutions series is a next-generation workstation software that integrates GC control, LC control, and additional improvements to functionality, while maintaining back-compatibility with the previous GCsolution. It offers sophisticated functionality, easy operation, highly extensible report functions, and other customizable features. In addition to inheriting these and other concepts from GCsolution, LabSolutions shares a common operating environment.
LabSolutions CS manages all analytical data on the network server, so that the data can be loaded to any computer connected to the network. In addition to sending analysis instructions, monitoring, and controlling instruments not directly connected to the computer (client computer), LabSolutions CS can also be used to directly control non-Shimadzu LC or GC units.
LabSolutions Direct is a new LabSolutions series remote access tool used to remotely control or monitor GC systems via a simple user interface on a commercially-available smartphone or tablet. Consequently, analyses can be performed while remotely monitoring the status of instruments from locations away from the laboratory.
The Nexis GC-2030 provides powerful support for configuring custom GC systems tailored to user needs. These systems are adjusted and tested at the factory for the given application before shipment, so they are ready to use for measurements as soon as they are delivered. That means no time is required for developing methods after the system arrives. Two TCD detectors and one FID detector can be installed at the same time. An optional valve box can be added to control up to eight valves from the original four.
Advanced Flow Technology (AFT) function increases analytical productivity with backflush, detector splitting, and other systems. With the Nexis GC-2030, methods can be specified either via the LabSolutions GC software or directly via the touch panel on the GC unit, without having to use any tedious specialized wizard software. It supports a variety of carrier gas control modes (such as constant linear velocity, constant flowrate, and constant pressure control modes), which ensures analytical conditions can be transferred smoothly from previous systems. Multiple AFT lines can be connected to the same GC unit as well.
Once target compounds have been detected, the backflush system reverses the carrier gas flow to discharge non-eluting components in the column through the injection port. This ability shortens analysis times and improves productivity.
Multiple chromatograms can be obtained at the same time by using the detector splitting system to split the flow exiting the analytical column and send the eluted components to multiple detectors. Consequently, much more information can be obtained from each analysis, which improves productivity by saving time and reducing costs.
Heart-cut is a method of performing separation using two columns with different selectivity. In this system, components that could not be separated by the first column are introduced into a second column with different properties, and further separation is performed. Heart-cut system can achieve high resolution performance analysis, which is normally difficult to attain by single column analysis.
Hydrogen can be a safe and highly effective carrier gas. As a highly efficient carrier gas with a flat Van Deemter curve, it maintains its separation efficiency across a wide linear velocity range. This makes it both a good substitute for Helium and also a great choice for speeding up analysis times. We know safety is paramount, which is why the Nexis GC-2030 offers an optional built-in hydrogen sensor*. It not only maintains a safe standby mode for early detection of any potential leaks, but also shuts off hydrogen flow. The main unit also includes an automatic carrier gas leak check function, which is very helpful when using hydrogen as a carrier gas.*Optional

The barrier discharge ionization detector (BID-2030) is a universal detector that offers high-sensitivity analysis by using a low-frequency dielectric barrier discharge plasma for ionization. The BID generates a helium (He) plasma by applying a high voltage to a quartz glass tube. The light energy from the He plasma then ionizes the target components and the ions are collected and output as peaks using a collection electrode. Its universal detection capability and high sensitivity make it the perfect choice for the analysis of inorganic gases and light hydrocarbons at ppm-level concentrations. The Nexis GC-2030 can be equipped with up to two BID-2030 detectors for increased productivity or separation versatility.
