Tailin Biotech ASE-24 Fully Automated TOC Sampling System (24-Position)

Overview

The Tailin Biotech ASE-24 Fully Automated TOC Sampling System is an engineered solution for unattended, high-integrity sample handling in regulated water quality laboratories. Designed specifically to interface with Tailin’s HTY-DI and HTY-GM series offline Total Organic Carbon (TOC) analyzers, the ASE-24 implements precise mechanical positioning and intelligent bottle detection to eliminate manual intervention during sampling sequences. Its operation is grounded in deterministic pneumatic actuation and optical presence sensing—ensuring consistent vial engagement, minimizing ambient air intrusion, and reducing system stabilization time prior to injection into the TOC analyzer. This architecture supports compliance-critical workflows in pharmaceutical purified water (PW), water for injection (WFI), clean steam condensate, and environmental monitoring applications where sample integrity, traceability, and repeatability are non-negotiable.

Key Features

• 24-position carousel with indexed, repeatable vial positioning—enabling full batch processing without operator involvement.
• Intelligent vial detection via integrated optical sensors that confirm presence, orientation, and cap integrity before aspiration—preventing dry draws and air entrainment.
• Dual operational modes: Analyzer-Synchronized Mode (triggered by HTY-DI/GM series analyzers via RS-232 or dry-contact I/O) and Time-Based Scheduled Mode (user-configurable interval-driven sampling independent of analyzer status).
• Low-power, fan-cooled electromechanical design rated at 40 W—suitable for continuous deployment in ISO Class 5–8 cleanrooms and QC laboratories.
• No consumables or routine calibration required; maintenance limited to periodic visual inspection and surface cleaning per GMP-aligned lab SOPs.
• Compact footprint (380 × 320 × 340 mm) optimized for benchtop integration adjacent to TOC analyzers—no external manifold or plumbing needed.

Sample Compatibility & Compliance

The ASE-24 accommodates standard 40 mL borosilicate glass vials with PTFE/silicone septa (e.g., ASTM D5907-compliant containers), as well as 20 mL vials using optional adapter inserts. It maintains sample containment integrity throughout transfer—critical for low-level TOC quantification (<50 ppb). The system is deployed in environments governed by USP , EP 2.2.44, JP 2.59, and ASTM D5907 methodologies. While the ASE-24 itself is not a measuring instrument, its deterministic sample presentation supports analytical validity under FDA 21 CFR Part 11 when paired with compliant TOC analyzers (e.g., HTY-DI1500 with audit trail and electronic signature capability). It aligns with ALCOA+ principles—ensuring data attributable, legible, contemporaneous, original, and accurate through synchronized timestamping with host analyzers.

Software & Data Management

The ASE-24 operates without embedded firmware or standalone software. All scheduling, triggering, and status reporting are handled externally by the connected TOC analyzer’s control system (e.g., HTY-DI1500’s built-in acquisition software). When operating in Analyzer-Synchronized Mode, each vial change event is logged with a UTC timestamp and mapped to the corresponding TOC measurement ID—enabling full chain-of-custody reconstruction in LIMS or ELN systems. No local data storage or user-accessible configuration interface exists on the ASE-24 unit, minimizing cybersecurity exposure and simplifying 21 CFR Part 11 validation scope. Audit trails are generated solely within the host analyzer’s validated software environment.

Applications

• Uninterrupted monitoring of PW/WFI distribution loops across multi-point sampling networks.
• Automated batch release testing of purified water in pharmaceutical manufacturing facilities.
• Environmental compliance testing of surface water, groundwater, and wastewater effluents per EPA Method 415.3.
• Long-term stability studies requiring hourly or diurnal TOC profiling over 72+ hours.
• Support for Annex 1 (EU GMP) environmental monitoring programs where manual sampling introduces contamination risk.

FAQ

Does the ASE-24 require calibration or periodic verification?
No. It contains no measuring components; performance verification is conducted via system suitability tests using certified TOC standards run through the full analyzer–sampler workflow.
Can the ASE-24 be used with non-Tailin TOC analyzers?
Not natively. It lacks universal protocol support (e.g., Modbus TCP, Ethernet/IP); integration is limited to Tailin’s HTY-DI and HTY-GM series via proprietary hardware handshake.
Is the ASE-24 suitable for use in Grade A cleanroom environments?
Yes—provided it is installed outside the critical airflow path and operated with appropriate gowning and aseptic technique during vial loading. Its IP20-rated enclosure meets typical cleanroom electrical safety requirements.
What happens if a vial is missing or improperly seated?
The optical detection system halts the sequence, illuminates a status LED, and signals an error code to the host analyzer—preventing invalid runs and preserving data integrity.
Does the ASE-24 support barcode scanning or LIMS integration?
No. Sample identification must be managed externally via analyzer software or manual entry; the ASE-24 provides only physical positioning and timing control.
