The importance of high-performance analytical instruments for monitoring microscopic quantities of compounds related to environmental pollution and human health, and for developing and evaluating new, highly functional materials and chemical products continues to grow. The GCMS-QP2020 has been designed to meet these needs.
AG视讯 Featuring enhanced instrument functionality, analysis software, databases, and a sample introduction system, the GCMS-QP2020 will help maximize the capabilities of your laboratory.

The vacuum exhaust system, which features a new differential exhaust turbomolecular pump, achieves the highest sensitivity under all GCMS conditions. In addition to helium, it can be operated with confidence using hydrogen or nitrogen as the carrier gas, which helps reduce operational costs. In addition, analysis times can be shortened while retaining high speed and high sensitivity, which contributes to the optimization of laboratory productivity.

AG视讯 The GCMS Insight software package dramatically improves the sensitivity and efficiency of multicomponent batch analysis. The Smart SIM method creation program creates methods to improve the sensitivity in multicomponent analysis. Further, LabSolutions Insight dramatically improves the efficiency of the data processing.

AG视讯 In addition to conventionally used mass spectra, qualitative analysis is supported by three types of valuable information: retention indices, molecular weight information from CI, and accurate mass*. Even higher level qualitative analysis can be performed by combining this information with mass spectra.

With a sample injection system that matches the sample form and the concentrations of the components being measured, as well as a 2D chromatography system that makes full use of the high-speed scan capability, you can configure optimal analysis systems to suit a variety of your analytical needs. And since all these analysis systems are supported by Shimadzu you can put your mind at ease when using them.

AG视讯 The instrument is a high-performance gas chromatograph mass spectrometer with advanced flow control system. At least three injection ports and four detector units can be installed on the same instrument at the same time, and the mass of the detector is not included. Equipped with a microcomputer workstation for chromatograph control and chromatographic data processing.
