Overview
The AIGIS AGS Valve Manifold Controller is an industrial-grade, open-architecture valve island module engineered for precise fluid routing and sequencing in analytical instrumentation systems. Designed specifically for integration into chromatographic platforms—including HPLC, UHPLC, GC, and preparative systems—the controller operates on electro-pneumatic actuation principles, enabling deterministic switching between multiple fluidic paths with minimal dead volume and pressure drop. Its modular architecture supports both low-pressure (≤10 bar) and high-pressure (up to 600 bar) valve configurations, making it suitable for applications ranging from sample dilution and column switching to multi-dimensional chromatography and automated derivatization workflows. Unlike proprietary valve controllers tied to single-instrument ecosystems, the AGS platform adheres to standardized I/O interfaces (24 VDC logic, opto-isolated digital inputs/outputs, RS-485 Modbus RTU), facilitating seamless integration with third-party PLCs, DAQ systems, and chromatography data systems (CDS).
Key Features
- Modular valve island design supporting single-valve and dual-valve configurations for scalable system integration
- Broad compatibility with AIGIS-certified valve families: low-pressure multi-port selector valves, high-pressure switching valves, planar-flow multi-channel valves, and multi-position multi-port injection valves
- Robust aluminum alloy housing with IP54-rated enclosure for laboratory and controlled industrial environments
- Integrated diagnostic LED indicators for real-time valve position feedback and fault detection (e.g., coil open circuit, pressure loss)
- Configurable dwell time, sequence delay, and interlock logic via onboard DIP switches or external command signals
- No internal firmware dependencies—operates as a deterministic hardware controller without embedded OS or network stack
Sample Compatibility & Compliance
The AGS Valve Manifold Controller imposes no intrinsic chemical compatibility limitations; compatibility is determined solely by the connected valve body materials (e.g., PEEK, stainless steel 316, Hastelloy C-276) and sealing elastomers (e.g., FKM, EPDM, Chemraz). It meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. While not a medical device itself, its use in IVD analyzers complies with ISO 13485-aligned manufacturing controls. For regulated pharmaceutical laboratories, the controller supports audit-ready operation when paired with validated valve modules and documented installation qualification (IQ) protocols—fully compatible with GLP and GMP environments where electronic record integrity is maintained through external CDS logging.
Software & Data Management
The AGS Valve Manifold Controller is a hardware-level actuation interface and does not include embedded software, GUI, or cloud connectivity. All control logic resides externally—in the host instrument’s firmware, a programmable logic controller (PLC), or chromatography data system (CDS). It supports deterministic, low-latency triggering via TTL-level digital signals or Modbus RTU commands over RS-485 (slave ID configurable, baud rates up to 115.2 kbps). Sequence logs, valve cycle counts, and error events must be captured and timestamped by the upstream system. When deployed in FDA-regulated environments (e.g., USP method transfers), the controller satisfies 21 CFR Part 11 requirements only when used within a validated system architecture—where electronic signatures, audit trails, and change control are implemented at the CDS or supervisory SCADA layer.
Applications
- Automated column selection and heart-cutting in comprehensive two-dimensional gas chromatography (GC×GC)
- Multi-solvent gradient programming in preparative HPLC systems with solvent selection manifolds
- Online solid-phase extraction (SPE) coupling with LC-MS/MS for environmental contaminant analysis (e.g., PFAS, pesticides)
- Sequential calibration standard introduction in ICP-MS and AA spectrometers
- Reagent routing in clinical chemistry analyzers requiring precise aspiration/dispense timing
- Method development support for multidimensional liquid chromatography (MDLC) with active flow splitting
FAQ
Is the AGS Valve Manifold Controller compatible with Agilent, Waters, or Thermo Fisher chromatography systems?
Yes—when interfaced via dry-contact relay outputs or Modbus RTU, it integrates with major CDS platforms using custom script modules or OEM-provided hardware abstraction layers.
Does it support analog input for pressure or flow feedback?
No—the controller is output-only; closed-loop feedback requires external transducers and a separate PID controller or PLC.
Can valve timing be synchronized to detector signal triggers?
Yes—TTL-compatible external trigger inputs allow precise synchronization with UV, MS, or conductivity detector event pulses.
What documentation is provided for validation in regulated labs?
A complete Factory Acceptance Test (FAT) report, material traceability certificates, and I/O pinout schematics are supplied; IQ/OQ protocols must be developed per site-specific risk assessment.
Is firmware upgrade capability available?
No—this is a fixed-function hardware controller with no flash memory or update interface; functional updates require hardware revision.
