HMS 100 UniStream Autosampler
Overview
HMS 100 is a UniStream Autosampler with three injection modes: liquid injection, static headspace injection, and solid phase microextraction (SPME) injection. The product is based on a closed-loop control XYZ three-dimensional mobile operation scheme, providing high-precision, high repeatability, high reliability, and high-efficiency intelligent program sampling function for laboratory analysis. Hyphenated with GC or GCMS, it can be applied to the analysis of odors in water, residual solvents in drugs, food flavors, environmental pollutants, and other fields.
Principle
Integrates all modules and tools required for liquid sampling, static headspace sampling, and solid-phase microextraction (SPME) workflows into a unified three-dimensional mobile platform. Preloaded samples (ranging from several to thousands of vials) are positioned on the sample tray. The autosampler executes fully automated sample pretreatment according to preset protocols and injects prepared samples into connected analytical instruments for subsequent analysis.
Features
Multi-Injection Modes: Supports liquid, static headspace, and SPME injection workflows.
Broad Compatibility: Seamlessly interfaces with mainstream chromatography (GC, HPLC) and chromatography-mass spectrometry (GC-MS, LC-MS) instruments.
Dual-Line Functionality: Enables simultaneous operation of two analytical systems with one autosampler.
High Reliability: Robust design ensures stable performance in high-throughput environments.
Real-Time Data Push: Delivers status updates and alerts to user-defined ports (e.g., email, mobile app).
Intuitive Wizard-Driven Operation: Guided setup for method creation and parameter configuration.
Historical Data Logging: Automatically archives experiment protocols, results, and user actions.
Priority & Queue Management: Supports urgent sample insertion and dynamic scheduling.
One-Click Calibration: Rapid verification of needle and tray positions for precision alignment.
Smart Error Diagnostics: Self-checking algorithms identify and report operational anomalies.
