This new high-end single-quad GCMS excels in both ease-of-use and robustness. The role of high-performance analytical instruments is expanding in areas as diverse as environmental pollution monitoring, forensics and material science. Whatever your field, the efficient and reliable GCMS-QP2020 NX is tailored to meet the needs of your laboratory.


GCMS-QP2020 NX overview

Smart Performance
  • Provides higher sensitivity and reduces operational costs: A large-capacity differential exhaust turbomolecular pump and a high-performance flow controller ensure that the utmost in sensitivity is obtained under all conditions used for GC. This sensitivity combined with high-speed analysis capabilities helps maximize laboratory efficiency by reducing analysis times. In addition, the system can be safely operated using carrier gases other than helium, such as hydrogen or nitrogen, thereby reducing operating costs.
  • Ion Source Featuring High Sensitivity and Long-Term Stability: The filament and the ion source box have been separated, which reduces the impact of the filament potential on the interior of the ion source. In addition, a shield is provided to block radiant heat generated by the filament, achieving a uniform temperature inside the ion source box. Thus, active spots inside the ion source are not prone to occur, enabling high-sensitivity analysis with long-term stability. (Patent: US7939810)
  • New Flow Controller Achieves Exceptional Reproducibility: A new flow controller (AFC) with a CPU uses various control methods to control carrier gas flow to a constant flow speed, flowrate, or pressure. It can also accurately trace the analytical conditions already being used. The split line filter can be replaced without any tools. Internal contamination can be confirmed visually, ensuring filters are replaced at the proper time.
  • Large-Capacity Differential Exhaust System: Through adoption of a new type of turbomolecular pump with increased exhaust efficiency, the system’s performance is greatly improved when using hydrogen or nitrogen, in addition to helium, as the carrier gas. Moreover, a differential exhaust method is used to create a vacuum separately for the ion source and the quadrupole. As a result, an optimal MS state can be realized regardless of the conditions imposed by the carrier gas used.
Smart Operation
  • Dramatic improvement in the efficiency of multicomponent simultaneous analysis: The efficiency of multi-component simultaneous analysis is dramatically improved thanks to Smart SIM™, which simplifies and automates the method creation, and LabSolutions Insight™ software, which greatly reduces the time needed for analyzing data. In addition, databases specialized for specific fields are provided, so regardless of the field in which quantitative analysis is to be performed, highly reliable data can be obtained as the result of the optimized analytical conditions.
  • More Convenient Multicomponent Analysis Achieved by Smart SIM: The Smart SIM automatic method creation function automatically configures the SIM program to suit the retention times. Even in cases where there are a number of compounds and they are apportioned to multiple methods, the methods can be integrated while maintaining the sensitivity as is. This significantly reduces the number of analysis cycles and the measurement time, improving productivity.
Smart Data Management
  • Easily obtains all the information required for qualitative analysis: With GC/MS, which has significant qualitative capabilities, a wealth of fragment information is obtained, so it is used as a means of identifying unknown compounds. A mass spectral library is generally used as a means of compound identification. However, experience with compound identification is required if the compound is not registered in the mass spectral library, or there are a number of compounds with similar structures. With the GCMS-QP2020 NX, in addition to the mass spectrum, three kinds of value-added compound information are used in combination to support high-accuracy qualitative analysis.
  • Databases Containing High Value-Added Retention Indices: Databases are available with retention indices specific to a variety of application fields, including foods, chemistry, fragrances, forensics, and metabolite component analysis. In addition to mass spectra, searches are performed in combination with retention indices, which are very highly compound specific, so isomers and compounds with similar structures are accurately identified.
  • Smart EI/CI Ion Source Easily Switches Between EI and CI Methods: The Smart EI/CI ion source has been developed in order to acquire CI data without switching the ion source, and without losing the sensitivity of EI, which is most commonly used. Even when it is difficult to perform identification with the EI mode using the mass spectral library, molecular weight information can be obtained from CI data, thus helping in the estimation of unknown compounds.
