Tester for Hydrocarbon Types in Liquid Petroleum Products by FIA – QualiLP™ 1319 Technical Parameters:

• Patented UV-Protective Enclosure — Operator Safety by Design: The instrument's patented environmentally-friendly secure enclosure structure physically separates the operator from the 365 nm ultraviolet lamp at all times during column observation and boundary measurement. This design eliminates direct UV exposure to eyes and skin — a significant improvement over open-lamp FIA tester designs — and makes compliance with occupational UV safety limits straightforward without requiring additional personal protective equipment or lab controls.
• Dual Simultaneous Column Operation — Double the Throughput: Two precision adsorption columns operate concurrently in a single test run, enabling two samples to be analyzed simultaneously. This dual-column design effectively doubles the analytical throughput of the instrument compared to single-column FIA testers — a significant productivity advantage in production laboratory environments where ASTM D1319 is run as a routine daily test on multiple fuel samples.
• Imported Precision Adsorption Columns — Consistent Separation Quality: The silica gel adsorption columns are sourced from precision manufacturers to ensure consistent packing density, uniform particle size distribution, and reproducible hydrocarbon zone separation from column to column and batch to batch. Consistent column quality is the foundation of reproducible FIA results, and the precision column specification of the QualiLP™ 1319 directly supports the interlaboratory precision requirements of ASTM D1319.
• In-Situ Column Cleaning — No Removal Required: The adsorption columns can be cleaned and regenerated without removing them from the instrument — a practical design feature that saves significant technician time, eliminates the risk of column damage from repeated removal and reinstallation, and reduces downtime between test sequences in high-volume production QC workflows.
• Secured Standard Oscillator — Reproducible Column Packing: An integrated standard oscillator is secured to the column housing and used to assist consistent compaction of the silica gel packing during column preparation and repacking. The controlled oscillation ensures uniform packing density across the column length — a critical factor in achieving reproducible hydrocarbon zone lengths and accurate SOA results that meet ASTM D1319 precision requirements.
• Movable Positioning Points — Precise Boundary Determination: Adjustable positioning points along the column allow the analyst to mark and record the exact locations of the aromatic, olefinic, and saturate zone boundaries under UV illumination with high repeatability. This design feature eliminates the subjective visual estimation of zone boundaries that is a source of operator-to-operator variability in FIA testing, providing a physical reference point for consistent boundary location between analysts and test runs.
• Flexible, Easily Connected Pipeline System: The solvent delivery and vent pipelines are designed for quick, reliable connection and disconnection without specialized tools or complex fittings. The flexible pipeline architecture simplifies setup, routine maintenance, and cleaning procedures — reducing the time and technical skill required for day-to-day instrument operation and minimizing the risk of connection errors that could affect test results.
• Dual Voltage Compatibility — 110 V or 220 V: The QualiLP™ 1319 is available in both 220 V (standard) and 110 V configurations, making it immediately compatible with North American laboratory electrical standards without requiring a step-up transformer. The 110 V version is specified at time of order, ensuring the correct configuration is delivered for the laboratory's power infrastructure.
