The Da Vinci Laboratory Solutions GC-Fractionator is a powerful platform for automated fraction collection directly from gas chromatographic separations. Using post-column solvent infusion, it isolates up to 384 precise fractions while maintaining parallel detection for full analytical traceability.

Developed for complex applications such as two-dimensional preparative GC, the system enables researchers to collect trace-level volatile compounds in sufficient purity for structural analysis by NMR. With multi-GC configurations available, the GC-Fractionator offers faster fractionation, higher resolution, and unmatched automation for advanced compound isolation and characterization.

The PIONA-VUV Analyzer combines GC–VUV spectroscopy with VUV Analyze Software to deliver rapid, automated fuel characterization. Using vacuum ultraviolet light, it provides both quantitative and qualitative data with unmatched selectivity—since nearly all gas-phase molecules absorb in the VUV region. Its advanced Time Interval Deconvolution (TID) algorithm automatically resolves overlapping peaks, enabling fast, reliable analysis of complex fuel samples without manual peak tables. The result is a powerful, easy-to-use solution for precise hydrocarbon and class-based identification in minutes.

DVLS GC-VUV PIONA Technical Details

Da Vinci Laboratory Solutions (DVLS) provides advanced chromatographic systems built on the Agilent LC platform, supporting both custom and standardized methods (ASTM, DIN, EN, IP). Solutions include HPLC for accurate component separation, UHPLC for faster, higher-resolution analyses, and LC-MS for detailed compound identification and quantification. Each configuration is engineered for precision, reliability, and flexibility, meeting the analytical demands of research and quality control laboratories worldwide.

The DVLS Fast Peroxide Analyzer (FPA) provides a safe, fast, and accurate alternative to traditional peroxide testing methods such as ASTM D2340 and E299. Built on an Agilent 1260 Infinity II HPLC platform with a dedicated reaction module, it automates the flow injection analysis of peroxides at ppb levels.

Using the iodometric reaction, peroxides in the sample react with iodide to form iodine, which is then detected by UV-VIS spectroscopy for precise quantification. The FPA determines both hydrogen and organic peroxides in various hydrocarbon and process streams—including butadiene, isoprene, aromatics, alcohols, and aviation fuels—ensuring reliable peroxide monitoring for safety and product quality.

The DVLS Diene Value (DV) Analyzer delivers fast, safe, and fully automated Diene Value measurements—providing a modern alternative to the traditional UOP 326 method. Using a Diels–Alder reaction with UV-VIS detection, it quantifies total diene content in just five minutes with minimal sample preparation and no hazardous reagents.

Proven to correlate with GC–MS/FID and GC–VUV results, the analyzer offers high sensitivity (0.5–100 DV), excellent repeatability (RSD < 4%), and no alcohol interference. Compact, accurate, and reagent-efficient, it ensures safer, faster quality control and process monitoring across diverse petrochemical streams.

The DVLS Mid Distillates Analyzer is a fully automated, HPLC-based alternative to the labor-intensive ASTM D1319 FIA method for determining aromatic hydrocarbon types in jet fuel and diesel. Built on the Agilent 1260 Infinity II LC and controlled through OPENLAB software, it supports ASTM D6379, D6591, IP391, IP436, IP548, and EN12916 methods with exceptional precision and reproducibility. The analyzer is available in two configurations: a standard normal-phase HPLC system and a backflush version for tri-aromatics (D6591) and reduced FAME interference (EN12916). Factory tested and installed on-site, it ensures reliable performance, streamlined automation, and consistent, FIA-equivalent results.

The DVLS Column Switching Module enhances HPLC productivity by allowing seamless switching between six, eight, or ten columns without manual reconnection. Designed to accommodate columns up to 30 cm at atmospheric temperature, the module features a VICI switching valve, solvent collection tray, and touchscreen interface for intuitive operation. This configuration enables efficient method flexibility, rapid column selection, and improved safety—providing a reliable, space-saving solution for multi-method HPLC workflows.

The DVLS Liquefied Gas Injector (LGI) is a safe, precise, and automated GC solution for sampling and analyzing impurities in liquefied gases such as LPG. Installed on an Agilent GC with a dedicated Pressure Station, the LGI uses a direct on-column injection technique that eliminates the risks of manual evaporation or liquid sampling valves. This ensures complete sample transfer and accurate quantification of impurities in mg/kg within 20 minutes. Compliant with ASTM D7756 and EN 16423, the LGI supports a wide range of applications including analysis of oily residues, amines, aromatics, sulfur compounds, oxygenates, and hydrocarbon composition in LPG and related streams.

The DVLS Pressure Station provides safe and representative sampling of gases and liquefied gases for chromatographic analysis. Integrated with the DVLS Liquefied Gas Injector, it maintains the sample in the liquid phase under constant pressure to ensure accurate and repeatable results. The system uses high-pressure nitrogen to control flow and outlet pressure, while a sight glass allows visual confirmation of the liquid phase. Compatible with various cylinder types and quick connectors, it can be configured for gases, liquefied gases, or both, and optionally includes a vaporizer to prevent sample freezing. The Pressure Station delivers a flexible, preparation-free solution for reliable GC or LC sample introduction.

The DVLS Multi Stream Gas Sampler automates the introduction of up to twelve gas samples from various containers—Tedlar bags, bladders, canisters, or cylinders—for fully unattended GC analysis. Compatible with Agilent OpenLab, EZChrom, ChemStation, and MassHunter software or standalone operation, it offers precise flow control, excellent repeatability, and overlapping sample intervals to maximize throughput. Designed for flexibility and reliability, the system seamlessly integrates with DVLS and third-party gas analyzers, eliminating manual intervention for efficient multi-sample analysis.

The DVLS³ Simply Smart Sensor provides a safe and intelligent solution for detecting hydrogen leaks in GC instruments. Installed inside the GC oven, it continuously monitors hydrogen concentration levels and automatically switches to an inert carrier gas when the Lower Explosive Limit (LEL) is reached, ensuring laboratory safety. The external controller displays real-time readings and triggers visual, acoustic, and electronic alerts (email, SMS, Growl, Prowl) when thresholds are exceeded. Compatible with all GC brands, the system can manage up to four sensors per controller to monitor hydrogen, temperature, pressure, or liquid levels, offering a versatile, automated safety solution for hydrogen-based GC operations.
