Titan Instruments Kylin S18 Atomic Fluorescence Spectrometer

Overview

The Titan Instruments Kylin S18 Atomic Fluorescence Spectrometer is a high-performance, multi-channel analytical instrument engineered for trace-level quantification of hydride-forming and cold-vapor elements in environmental, food, clinical, pharmaceutical, geological, and industrial matrices. Based on the principle of atomic fluorescence spectroscopy (AFS), the Kylin S18 excites ground-state atoms—generated via chemical vapor generation (CVG) or cold vapor atomic fluorescence (CV-AFS)—using element-specific hollow cathode lamps (HCLs), and measures the intensity of characteristic fluorescent emission at defined wavelengths. Its orthogonal dual-beam optical architecture minimizes stray light interference, while the integrated temperature-controlled quartz-trap atomizer ensures optimal atomization efficiency across a broad thermal range (100–350 °C). Designed for regulatory compliance and laboratory productivity, the Kylin S18 delivers sub-part-per-trillion detection sensitivity, exceptional long-term stability (RSD < 0.6%), and linear response over three decades—meeting method requirements for routine analysis under ISO/IEC 17025-accredited laboratories.

Key Features

• Four-channel simultaneous detection capability for As, Se, Pb, Bi, Sb, Te, Sn, Hg, Cd, Ge, Zn, and Au—enabling rapid multi-element screening without re-injection.
• Dual sequential injection pump system with integrated fluidic control, delivering high-precision sample/reagent metering and reproducible hydride generation kinetics.
• Orthogonal double-optical-path design with matched photomultiplier tube (PMT) channels, ensuring identical optical path lengths and enabling real-time reference beam drift correction for enhanced accuracy.
• Intelligent plug-and-play hollow cathode lamps with auto-identification and built-in lamp-hour tracking; lamp current and ignition status monitored in real time.
• Advanced EFC (Electronic Flow Control) gas management system with continuous pressure and mass flow monitoring, automatic fault alerts, and programmable flow profiles per analytical sequence.
• Carbon-fiber-reinforced PTFE sampling probes—replacing fragile quartz needles—to improve mechanical durability and reduce maintenance downtime.
• Comprehensive self-diagnostic suite covering optical alignment, vapor generation unit, atomizer integrity, gas flow stability, liquid level sensors, and lamp functionality—providing actionable fault codes and guided troubleshooting.
• Graphical user interface with real-time visualization of instrument status, temperature gradients, flow rates, and lamp parameters—optimized for operational transparency and operator confidence.

Sample Compatibility & Compliance

The Kylin S18 supports aqueous samples prepared by acid digestion, microwave-assisted digestion, or direct dilution—compatible with solid, liquid, and semi-solid matrices including drinking water, wastewater, soil extracts, biological tissues (blood, urine, hair, nails), food products (dairy, meat, wine, feed), tobacco, petroleum fractions (crude oil, lubricants), metallurgical slags, ores, alloys, and pharmaceutical excipients. It conforms to multiple international and national standard methods, including but not limited to: GB 5009.11–2014 and GB 5009.17–2014 (China Food Safety Standards), HJ 694–2014 (Water Quality), HJ 680–2013 (Soil and Sediments), HJ 542–2010 (Ambient Air), HJ 702–2014 (Solid Waste), and ASTM D6720–22 (Petroleum Products). The system architecture supports GLP/GMP workflows through full audit trail logging, role-based access control, electronic signature enforcement, and method versioning—all aligned with FDA 21 CFR Part 11 data integrity requirements.

Software & Data Management

The Kylin S18 operates under a dual-language (English/Chinese), modular software platform compliant with modern laboratory informatics standards. Core modules include method editor with customizable calibration curves (linear, quadratic, weighted), automated QC check routines (spike recovery, duplicate analysis, blank monitoring), and report generator supporting PDF, Excel, and LIMS-export formats. All data operations—including parameter changes, calibration updates, sample injections, and maintenance logs—are timestamped, user-attributed, and immutable once archived. Audit trail records preserve full context: who performed what action, when, and why—enabling seamless internal audits and regulatory inspections. Data backups are encrypted and support network storage integration via configurable SMB/NFS protocols.

Applications

• Environmental Monitoring: Quantification of As, Hg, Sb, and Se in surface water, groundwater, wastewater effluents, and contaminated soils per EPA and Chinese HJ methods.
• Food & Agriculture Safety: Routine screening of total and inorganic arsenic in rice, mercury in fish tissue, cadmium in grains, and lead in infant formula—aligned with Codex Alimentarius and GB 5009 series.
• Clinical & Toxicological Testing: Trace metal profiling in human biofluids and tissues for occupational exposure assessment, nutritional studies (e.g., selenium status), and heavy metal poisoning diagnostics.
• Pharmaceutical Quality Control: Elemental impurity testing of active pharmaceutical ingredients (APIs) and excipients per ICH Q3D guidelines, particularly for Class 1 (As, Cd, Hg, Pb) and Class 2A (Co, Ni, V) elements.
• Geological & Metallurgical Analysis: Determination of ultra-trace gold in rock digests, bismuth and tellurium in sulfide concentrates, and germanium in semiconductor-grade silicon feedstock.
• Petrochemical QA/QC: Mercury speciation screening in crude oil and refined fuels using cold-vapor AFS, supporting refinery process control and pipeline corrosion mitigation strategies.

FAQ

What hydride-forming elements can the Kylin S18 quantify simultaneously?
The instrument supports concurrent measurement of up to four elements from the following group: As, Se, Pb, Bi, Sb, Te, Sn, Cd, Ge, and Zn.
Does the Kylin S18 comply with FDA 21 CFR Part 11 requirements?
Yes—the software includes electronic signatures, audit trail logging, role-based permissions, and data immutability features validated for regulated environments.
Is external cooling required for the PMT detector?
No—the photomultiplier tube operates at ambient temperature within its specified 160–320 nm spectral window and does not require thermoelectric or liquid nitrogen cooling.
Can the Kylin S18 be integrated into a laboratory information management system (LIMS)?
Yes—it supports standardized data export (CSV, XML) and optional OPC UA or HL7 interfaces for bidirectional LIMS connectivity.
What maintenance intervals are recommended for the dual sequential injection pump?
Pump tubing and valves should be inspected every 500 runs; full calibration verification is advised quarterly or after any major hardware service event.
