SCION 436-GC Specification Sheet

Significance of the topic

Gas chromatography remains a cornerstone analytical technique for separation, identification and quantification of volatile and semi-volatile compounds across fields from environmental monitoring to pharmaceutical development. Detailed understanding of instrument capabilities is essential for method selection, optimization and compliance with regulatory standards.

Objectives and Overview

This specification sheet summarizes the technical performance, design features and operational parameters of the SCION 436-GC gas chromatograph, highlighting its suitability for research, QA/QC and industrial applications.

Used Instrumentation

• GC model: SCION 436-GC with column oven and full color TFT touch display
• Injectors: electronic flow control (EFC) supported modules for split/splitless, programmable temperature vaporizing (PTV), cold on-column (COC), flash and packed wide-bore injectors
• Detectors: up to two detectors including FID, TCD, ECD, NPD, PFPD, PDHID or mass spectrometry
• Automation: 8410 autoinjector and 8400 autosampler for liquid injection, headspace, SPME and temperature-controlled sampling

Methodology and Technical Features

• Oven temperature range from –160 °C (with N₂ cooling) to 450 °C; maximum ramp rates up to 170 °C/min
• Retention time repeatability <0.008 % and area repeatability <1 % RSD under programmed conditions
• Electronic flow control for precise pressure and flow regulation (0.1 % full scale accuracy)
• Communication via Ethernet TCP/IP, digital I/O, analog outputs and synchronization signals
• Data acquisition and control managed by CompassCDS chromatography data system
• Multilingual local interface, method storage up to 50 methods, extensive logging capabilities
• Certifications: UL, CSA, IEC 61010, EMC compliance and ATEX

Results and Discussion

Performance metrics demonstrate high sensitivity (e.g. FID detectivity 1.4 pg C/s, ECD 7 fg/s), broad dynamic ranges (up to 10^7 for FID) and robust temperature control with minimal ambient influence. Dual-injector and dual-detector flexibility allow simultaneous analyses and backflush options increase throughput and sample integrity.

Benefits and Practical Applications

• Versatile injector and detector combinations support diverse sample types from environmental pollutants to complex biological matrices
• High temperature and flow control precision ensure reproducibility for regulatory QA/QC
• Automated sampling and multilingual interface streamline laboratory workflows
• Compact footprint and wide environmental tolerance facilitate installation across research and industrial labs

Future Trends and Potential Applications

Advances may include integration of real-time data analytics, miniaturized and portable GC platforms, enhanced mass spectrometry coupling and smarter automation to meet growing demands in on-site monitoring, high-throughput screening and remote operation.

Conclusion

The SCION 436-GC offers a combination of precise temperature control, sensitive detection, flexible automation and robust design, positioning it as a reliable workhorse for a broad range of gas chromatographic applications.
