Tailin Biotech ASE-70A Automatic TOC Sampler (70-Position)

Overview

The Tailin Biotech ASE-70A Automatic TOC Sampler is an engineered solution for high-throughput, unattended sample introduction in regulated water quality laboratories performing Total Organic Carbon (TOC) analysis. Designed specifically to interface with Tailin’s HTY-DI and HTY-GM series offline TOC analyzers, the ASE-70A operates on a dual-mode architecture—either synchronized via digital handshake (RS-232 or TTL-level trigger signals) with the host analyzer (Online Mode), or autonomously executing time-triggered sampling sequences (Scheduled Mode). Its core function is to eliminate manual vial handling while preserving analytical integrity: integrated bottle presence detection prevents air aspiration during aspiration cycles, minimizing baseline drift and reducing system equilibration time prior to injection. The device employs a precision stepper-motor-driven carousel and pneumatically actuated syringe pump for consistent draw volume and positional repeatability—critical for compliance with pharmacopeial methods requiring strict sample sequence traceability.

Key Features

• 70-position carousel with real-time position indexing and automatic mechanical reset upon power-up or cycle completion
• Intelligent bottle detection using combined vacuum feedback and optical sensing—eliminates false triggers from empty or misaligned vials
• Two operational paradigms: (1) Analyzer-controlled mode—accepts external start/next commands from HTY-DI1000-PL, HTY-DI1500, HTY-GM2000, or HTY-GM3000; (2) Standalone scheduled mode—configurable interval-based sampling (e.g., every 5, 10, 30, or 60 minutes)
• No dedicated operator training required—intuitive front-panel interface with LED status indicators and tactile button navigation
• Low-power design (40 W nominal) compatible with universal AC input (100–240 VAC, 50/60 Hz), suitable for ISO Class 5–8 cleanroom environments and QC labs operating under 21 CFR Part 11-aligned workflows
• Robust aluminum alloy frame with chemical-resistant surface coating—optimized for aqueous sample matrices including purified water (PW), water for injection (WFI), and clean steam condensate

Sample Compatibility & Compliance

The ASE-70A accommodates standard 40 mL borosilicate glass vials with PTFE-lined screw caps (dimensions: Ø28 mm × 95 mm height), conforming to USP and EP 2.2.44 requirements for TOC sample containment. It does not support non-standard vial geometries or polymer containers subject to extractables interference. All fluid-path components contacting samples are constructed from inert materials—PTFE tubing, ceramic syringe barrels, and stainless-steel actuators—to prevent carbon leaching or catalytic degradation. The system supports audit-trail-capable operation when paired with Tailin’s compliant TOC analyzers running firmware v3.2+, enabling full traceability of vial position, timestamp, and mode selection per injection event—essential for GLP and GMP validation documentation per Annex 11 and ISO/IEC 17025:2017 clause 7.7.

Software & Data Management

While the ASE-70A operates as a hardware peripheral without embedded software, its communication protocol is fully documented in Tailin’s Application Integration Guide (Ref. T-DOC-AI-ASE70A-Rev.D). In Online Mode, it accepts ASCII command sets over RS-232 (default: 9600 baud, N-8-1), enabling seamless integration into LIMS-driven workflows or custom SCADA platforms. Scheduled Mode parameters—including start time, interval, and total cycle count—are configured via onboard DIP switches and retained in non-volatile memory across power cycles. No local data storage or user-accessible logs reside on the device; all acquisition metadata is generated and archived exclusively by the connected TOC analyzer, ensuring alignment with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Applications

• Pharmaceutical water system monitoring: continuous PW/WFI loop surveillance per FDA Guidance for Industry (2022) and EU GMP Annex 1 (2022 revision)
• Biotechnology process water qualification: feedwater, buffer, and final rinse monitoring during equipment cleaning validation
• Medical device manufacturing: TOC verification of ultrapure rinse water used in critical component washing
• Contract testing laboratories: batched analysis of environmental monitoring samples (e.g., HVAC condensate, cleanroom sink effluent) with minimal analyst intervention
• Academic research: long-duration kinetic studies requiring hourly TOC sampling over 72+ hour periods without overnight staffing

FAQ

Is the ASE-70A compatible with non-Tailin TOC analyzers?

No—the mechanical interface, electrical signaling, and command syntax are proprietary to Tailin’s HTY-DI and HTY-GM series. Third-party integration requires formal technical collaboration and hardware adaptation.
Does the sampler include a built-in calibration verification function?

No—it is a sample-handling module only. Calibration verification must be performed at the TOC analyzer level using certified sucrose or potassium hydrogen phthalate standards per USP .
What is the maximum allowable vial height deviation before detection failure occurs?

The optical sensor tolerates ±2 mm vertical variance; vials exceeding this tolerance require manual reseating prior to run initiation.
Can the ASE-70A operate inside a laminar flow hood?

Yes—its IP20-rated enclosure and absence of internal fans permit safe placement within ISO Class 5 hoods, provided ambient temperature remains between 15–30 °C and relative humidity stays below 80% non-condensing.
Is firmware upgrade capability supported?

Firmware updates are exclusively performed by authorized Tailin service engineers using diagnostic USB interfaces; no field-upgradeable firmware is exposed to end users.
