Provides Higher Sensitivity and Reduced Operation Costs

A new turbomolecular pump with improved exhaust efficiency has been adopted. This significantly improves performance when not only helium but also hydrogen or nitrogen is used as the carrier gas. In addition, the differential exhaust system evacuates the ion source and quadrupole separately, thereby achieving the optimal MS state under all carrier gas conditions.

High Performance Ion Source
High sensitivity, stable analysis is achieved by incorporating patented technology for the ion source. In addition, the system is equipped with a Quick-CI function that enables checking molecular ions in CI mode without stopping the MS. This demonstrates its capabilities in both quantitative and qualitative analyses. * Limited to the NCI model.

High-Performance Gas Chromatograph
Long-term stability is achieved for retention times thanks to AFC (advanced flow control) with built-in compensating technology for room temperature fluctuations. In addition, the constant linear velocity control mode keeps the linear velocity of the carrier gas constant even if the column oven temperature changes, so the best GC separation is always achieved.

High-Speed Scan Control Technology Advanced Scanning Speed Protocol (ASSP™）
The rod bias voltage is automatically optimized during hight-speed data acquisition, which minimizes sensitivity deterioration during high-speed scans of 10,000 u/sec or faster. The sensitivity obtained is at least five times better than with conventional systems. This is effective for scan data sensitivity improvements and favorable mass spectrum acquisition, particularly in high-speed analysis with Fast-GC/MS, simultaneous Scan/SIM, FASST analysis, and applications using GC × GC-MS. (Patent: US6610979)

Chromatogram Intensities at Different Scan Speeds

Dramatic Improvement in the Efficiency of Multicomponent Simultaneous Analysis

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.

Multi-analyte Data Review
With LabSolutions Insight software, quantitative results for a complete series of data files can be displayed side-by-side for comparison and QC review. All of the chromatograms for a selected target compound can be displayed simultaneously, making it easy to review the detected peaks and confirm the quantitative results. Color-coded QA/QC flags quickly identify any outliers that require further examination.

Color-coded QA/QC Flags
In LabSolutions Insight, quantitative results can be compared to established criteria, and any outliers are color-coded for easy identification and further review. Five color-coded criteria levels can be defined, making it easy to determine which data points are outliers, and which specific QC criteria were not met. Any changes made to calibration curves or manual peak integration are immediately reflected in the color-coded flags.

Example of Using Flags for Quantitative Review
The following example illustrates how an orange flag was set to identify moldy odor compound concentrations that exceeded a defined cautionary limit of 1.0 ppt (part-per-trillion), and a red flag was used as a warning to identify those which had exceeded 10 ppt. In the figure below, quantitative results are tabulated at the top of the screen, while the bottom of the screen simultaneously displays peak identification and integration. Both views include the color-coded flags.

System Configurations Using Multiple Client Computers
Data acquired from multiple analyses can be reviewed or confirmed using client computers connected via a LAN or other network. If multiple systems are used, data obtained from each system can be reviewed from any client computer. Even in the case of multiple analysts using the same system, the ability to separate analytical work from measurement work improves work efficiency.

Databases with Retention Indices to Support Analysis
There are databases for environmental analysis, food analysis, and biological sample analysis. Retention indices can be used effectively for the identification of components and the adjustment of retention times.

Automatic Adjustment of Compound Retention Time (AART)
The AART (Automatic Adjustment of Retention Time) function can estimate the retention times of target components from retention indices and the retention times of an alkane standard mix*.

* Requires alkane mix which is sold separately.

Compound Composer Database Software for Simultaneous Analysis (Environmental Analysis)
Simultaneous GC/MS analysis supporting identification and quantification of 942 environmental pollutants can be performed. The retention times and calibration curve information of environmentally hazardous chemical substances are registered, so approximate concentrations can be obtained, even when it is difficult to obtain standards.

Comprehensive Qualitative Functions
With GCMSsolution, multiple retention index groups can be selected, and searches can be narrowed using a variety of conditions. Accurate qualitative analysis can be performed even for isomers with similar mass spectra. (These functions can be used with the pesticide library and the toxicological database.)
